sympathicotomy may cause a temporary impairment of the caudal-to-rostral hierarchy of thermoregulatory control and changes in microcirculation

Patients with palmar hyperhidrosis have been reported to have a much
more complex dysfunction of autonomic nervous system, involving compensatory high parasympathetic
activity as well as sympathetic overactivity (13, 14), suggesting that sympathicotomy initially induces a
sympathovagal imbalance with a parasympathetic predominance, and that this is restored on a
long-term basis (14). Therefore, thoracic sympathicotomy may cause a temporary impairment of the
caudal-to-rostral hierarchy of thermoregulatory control and changes in microcirculation. The reduction
of finger skin temperature on the non-denervated side may be due to either a decrease in the cross-
inhibitory effect or the abnormal control of the inhibitory fibers by the sudomotor center (6).
Vasoconstrictor neurons have been found to be largely under the inhibitory control of various afferent
input systems from the body surface, whereas sudomotor neurons are predominantly under excitatory
control (15). The basic neuronal network for this reciprocal organization is probably located in the spinal
level (15). Therefore, the reduction in the contralateral skin temperature may be explained by cross-
inhibitory control of various afferent in the spinal cord.
In particular, our study showed that, following bilateral T3 sympathicotomy, the skin temperatures on
the hands increased whereas the skin temperatures on the feet decreased. These findings suggest a
cross-inhibitory control between the upper and lower extremities. However, the pattern of skin
temperature reduction on the feet differed from that on the contralateral hand. The skin temperature on
the feet did not decrease after right T3 sympathicotomy but decreased significantly after bilateral T3
sympathicotomy.

sympathectomy results in a pronounced increase of cerebrospinal fluid production

Electrical stimulation of the sympathetic nerves, which originate in the superior cervical ganglia, induces as much as 30% reduction in the net rate of cerebrospinal fluid (CSF) production, while sympathectomy results in a pronounced increase, about 30% above control, in the CSF formation. There is strong reason to believe that the choroid plexus is under the influence of a considerable sympathetic inhibitory tone under steady-state conditions.

Effect of ganglion blockade on cerebrospinal fluid norepinephrine

Prevention of ganglion blockade-induced hypotension using phenylephrine did not prevent the decrease in CSF NE caused by trimethaphan, and when phenylephrine was discontinued, the resulting hypotension was not associated with increases in CSF NE. The similar decreases in plasma NE and CSF NE during ganglionic blockade, and the abolition of reflexive increases in CSF NE during hypotension in ganglion-blocked subjects, cast doubt on the hypothesis that CSF NE indicates central noradrenergic tone and are consistent instead with at least partial derivation of CSF NE from postganglionic sympathetic nerve endings.

Post sympathectomy syndrome is a poorly understood condition

Post sympathectomy syndrome is a poorly understood condition, which occurs in up to 50% of patients undergoing sympathectomy. This is proposed to be a complex neuropathic and central deafferentation and reafferentation sydnrome. This can occur anywhere from few days to weeks following chemical or surgical sympathectomy. This is characterized by deep, aching pain with superficial burning and hyperesthesia, which may or may not respond to narcotic analgesics. Tricyclic antidepressants may help to reduce the incidence of postsympathoctomy neuralgia. Phenytoin, Carbamazepine or Gabapentin may be useful to reduce spontaneous pain and allodynia. Mexiletine and I.V. lignocaine may help some patients. Occasionally invasive therapies like sympatheic block or more complete sympathectomy can also help.

Stellate ganglion block is one of the most frequently performed procedures in he practice of chronic pain. It can provide good diagnostic, therapeutic and prognostic value.
It can produce complete sympathectomy to the head and neck structures but only a partial sympathetic block of the upper extremity in some patients with variation in anatomy.

Sympathectomy useless, even detrimental

A number of surgical procedures have been developed, which, although well-intentioned, are found unfortunately by further study to prove useless, or even detrimental. It is believed at present that lumbar sympathetic ganglionectomy in the treatment of the post-thrombotic type of ulceration of the lower extremity should be placed in this category.

After peripheral nerve section the amount of GAL produced and present in sensory fibers proximal to the section is dramatically upregulated

Front Neuroendocrinol. 1992 Oct;13(4):319-43.

Galanin in sensory neurons in the spinal cord.

Department of Clinical Physiology, Karolinska Institute, Huddinge University Hospital, Sweden.

The distribution and physiological effects of the neuropeptide galanin (GAL) have been examined in the somatosensory system. GAL is normally present in a few sensory neurons that terminate in the dorsal horn of the spinal cord and it is colocalized with substance P and calcitonin gene-related peptide. After peripheral nerve section, but not dorsal root section, the amount of GAL produced and present in sensory fibers proximal to the section is dramatically upregulated. In parallel functional studies, we could demonstrate that exogenous GAL has a complex effect on the spinal cord reflex excitability, facilitatory at low doses and inhibitory at high doses. Furthermore, GAL inhibits the effect of excitatory neuropeptides physiologically released at the peripheral and central terminals of small diameter afferents that subserve a nociceptive function. After axotomy, the inhibitory effect of GAL is increased. We conclude that GAL may have an important role in the control of nervous impulses that underlie pain states that can occur after peripheral nerve injury.

Increased expression of galanin in the rat superior cervical ganglion after pre- and postganglionic nerve lesions

http://www.ncbi.nlm.nih.gov/pubmed/7515354

Galanin is a neuropeptide encoded by the GAL gene,^[1] that is widely expressed in the brain, spinal cord, and gut of humans as well as other mammals. Galanin signaling occurs through three G protein-coupled receptors.^[2]
The functional role of galanin remains largely unknown; however, galanin is predominately involved in the modulation and inhibition of action potentials in neurons. Galanin has been implicated in many biologically diverse functions, including: nociception, waking and sleep regulation, cognition, feeding, regulation of mood, regulation of blood pressure, it also has roles in development as well as acting as a trophic factor.^[3] Galanin is linked to a number of diseases including Alzheimer’s disease, epilepsy as well as depression, eating disorders and cancer.^[4][5] Galanin appears to have neuroprotective activity as its biosynthesis is increased 2-10 fold upon axotomy in the peripheral nervous system as well as when seizure activity occurs in the brain. It may also promote neurogenesis.^[2]

Compensatory changes in contralateral sympathetic neurons of the superior cervical ganglion and in their terminals in the pineal gland following unilateral ganglionectomy

The sympathetic noradrenergic neurons of the rat superior cervical ganglia (SCGs) provide the major source of innervation to the pineal gland. The present study sought to determine if this sympathetic innervation can undergo collateral sprouting following partial denervation of the pineal by unilateral removal of the SCG (ganglionectomy), and whether such growth of axon terminals is associated with biochemical changes in the contralateral SCG. In the pineal gland following partial denervation, residual noradrenergic terminals underwent compensatory changes indicative of collateral sprouting, as evidenced by: a rapid reduction in tyrosine hydroxylase (TH) activity and in [3H]norepinephrine (NE) uptake, to about 50% of control by 2 days, which was followed by a gradual but sustained increase to levels of approximately 80% of control by 10 days and a reduction in the intensity and density but not in the distribution of fibers containing NE-induced fluorescence by 2 days, which was followed by a sustained increase. In the contralateral SCG, choline acetyltransferase (CAT) activity, a marker of cholinergic preganglionic terminals, was transiently increased to about 115% of control by 4 days and returned to control levels by 14 days after unilateral ganglionectomy; later, TH activity in noradrenergic cell bodies was gradually increased to about 140% of control by 10 days where it remained for up to 52 days. Unilteral ganglionectomy combined with decentralization of the contralateral SCG by preganglionic nerve cut prevented the compensatory changes in noradrenergic nerve terminals within the pineal.

Hypertrophy and neuron loss: structural changes in sheep SCG induced by unilateral sympathectomy

Interaction effects between time and ganglionectomy-induced changes were significant for SCG volume and mean perikaryal volume. These findings show that unilateral superior cervical ganglionectomy has profound effects on the contralateral ganglion. For future investigations, it would be interesting to examine the interaction between SCGs and their innervation targets after ganglionectomy. Is the ganglionectomy-induced imbalance between the sizes of innervation territories the milieu in which morphoquantitative changes, particularly changes in perikaryal volume and neuron number, occur? Mechanistically, how would those changes arise? Are there any grounds for believing in a ganglionectomy-triggered SCG cross-innervation and neuroplasticity?

Retrograde Changes in the Nervous System Following Unilateral Sympathectomy

In consequence of right-sided smpathectomy at the level of C5 it was found that in the sheep the cervical sympathetic trunk contains nerve fibres which proceed from cells situated in the first four segments of the thoracic part of the spinal cord and in the stellate ganglion. These fibres are about 85 per cent of all fibres of the sympathetic trunk. The remaining 15 per cent proceed from nerve cells situated nasally of the anterior cervical ganglion.

Telaranta's patient commits suicide after elective surgery for sweaty hands

One of Dr. Telaranta’s patients who had made a complaint began to experience strong reactions of anxiety which did not go away even after corrective surgery. Later the patient committed suicide.

Surgery involving the clamping of sympathetic nerve trunks to prevent excessive perspiration and blushing appears to be of questionable value.
Complications have been reported, ranging from phantom perspiration to blood clots in the brain.
The Finnish Office for Health Care Technology Assessment (FinOHTA), which is part of the National Research and Development Centre for Welfare and Health (STAKES) recently conducted a survey on the various effects of hyperhidrosis surgery at the request of the Finnish Medical Association.
Finnish surgeon Timo Telaranta has performed about 2,000 such operations at private clinics in Helsinki and Oulu in the past ten years.

The National Authority for Medicolegal Affairs has issued three warnings to Telaranta and the Provincial Government of Southern Finland has issued one.



Many doctors have serious reservations about the idea of treating complaints such as excessive perspiration, blushing, and performance anxiety by severing people’s nerves.

The amount of compensatory sweating depends on the patient, the damage that the white rami communicans incurs, and the amount of cell body reorganization in the spinal cord after surgery.

Other potential complications include inadequate resection of the ganglia, gustatory sweating, pneumothorax, cardiac dysfunction, post-operative pain, and finally Horner’s syndrome secondary to resection of the stellate ganglion.

ETS considered psychiatric surgery - says Dr Nagy

"ETS can alter many bodily functions, including sweating , heart rate , heart stroke volume , blood pressure , thyroid , baroreflex , lung volume , pupil dilation, skin temperature, goose bumps and other aspects of the autonomic nervous system . It can diminish the body's physical reaction to exercise and/or strong emotion, and thus is considered psychiatric surgery. In rare cases sexual function or digestion may be modified as well. "

Individual cardiovascular response to different levels of sympathetic blockade varies widely, depending on the degree of sympathetic tone before the block

The cardiovascular responses to epidural anaesthesia are almost entirely due to the fact that the local anaesthetic injected into the epidural space not only blocks somatic, sensory and motor fibres, but also produces preganglionic sympathetic denervation.

Postganglionic sympathetic nerves play an important role in controlling cardiac function and vascular tone. The most important of the cardiovascular effects are related to blockade of vasoconstrictor fibres (below T4) with resulting dilatation of resistance and capacitance vessels and/or cardiac sympathetic fibres with loss of chronotropic and inotropic drive to the myocardium (T1-5) (Figure 1).

The cardiac sympathetic outflow emerges from C5 to T5 levels, with the main supply to the ventricles from T1 to T43. A significant part of the chronotropic and inotropic control of the heart is mediated through the upper four thoracic spinal segments.
Denervation of preganglionic cardiac accelerator fibres leaving the cord at T1-T5 results in minimal vasodilatory consequences. Changes however in heart rate, left ventricular function and myocardial oxygen demand may occur due to high thoracic epidural blockade and are discussed below.

The major determinant of heart rate is the balance between sympathetic and parasympathetic systems with the latter predominating. A high thoracic epidural anaesthesia (TEA) covering the cardiac segments (T1-T4) produces small but significant reductions in heart rate4-8. During cardiac sympathetic denervation, parasympathetic cardiovascular responses, including those involved in baroreflexes, may dominate.


It was suggested that the sympathetic control of heart rate modified the dominating parasympathetic tone, rather than functioning as an active cardiac accelerator. In this study there was no compensation for changes in preload;
therefore cardiopulmonary baroreceptors affected by changes in central volume secondary to peripheral vasodilatation or vasoconstriction might have altered arterial baroreceptor heart rate reflex as well.



High TEA added to general anaesthesia significantly decreased the cardiac acceleration in response to decreasing blood pressure, suggesting that baroreflex-mediated heart rate response to a decrease in arterial blood pressure depends on the integrity of the sympathetic nervous system. However general anaesthesia, in addition to high levels of epidural anaesthesia, may have modified the balance between sympathetic and parasympathetic tone as well.
By applying power spectral analysis, i.e., frequency analysis of electrocardiographic R-R interval, the individual components of the autonomic nervous system can be discerned and can be used as a sensitive indicator of sympathovagal interaction.


Individual cardiovascular response to different levels of sympathetic blockade varies widely, depending on the degree of sympathetic tone before the block.

diabetic autonomic neuropathy has already sympathectomized the patient

Although not specific, the symptoms suffered by diabetics from sweating disturbances are fairly typical [5]. Initially there is heat intolerance accompanied by hyperhidrosis of the upper half of the body, particularly affecting the face, neck, axillae and hands. It is of interest that these patients rarely perspire excessively below the umbilicus. This diabetic syndrome has been attributed to a lesion of the sympathetic nerve fibres which control sweat secretion [11] and follow the course of the peripheral nerves [12]. This affects the efferent branch of the reflex arch and is identical to that occurring distal to a surgical sympathectomy [13].

There was no difference found between the histological changes in the nerves of the spontaneous anhidrotic patients
(Fig. 1) and those of the two previously sympathectomized patients.

A number of papers have been published which stressed [22-24] the high failure rate of sympathectomy operations in diabetics. We believe that the failure of the operation is due to the fact that diabetic autonomic neuropathy has already sympathectomized the patient. The results of the present study are compatible with this idea.

Sympathectomy decreased CD4+ T-cells in lymph nodes

Alterations in lymphocyte activity does not always correlate with changes in the proportions of T- or B-lymphocyte subsets. Sympathetic denervation leads to loss of an important regulatory mechanism in immune system physiology. This is apparently site specific in that both lymph node and spleen T-cell proliferative responses are reduced.

Deceit and fraud in medical research

Deceit and fraud in medical research is a serious problem for the credibility of published literature. Although estimating its prevalence is difficult, reported incidences are alarming. The spectrum of the problem ranges from what may seem as rather innocuous gift authorship to wholesale fabrication of data. Potential factors which may have promoted fraud and deceit include financial gain, personal fame, the competitive scientific environment and scientific hubris. Fraud and deceit are difficult to detect and are generally brought to the fore by whistleblowers.

sympathectomy will block the chronotropic response

Around 50% of patients have bradycardia in the following minutes of a bilateral surgery with mean and diastolic blood pressure significant reduction. Since the sympathectomy will block the chronotropic response, a significant increase of the ejection volume is observed when the patient moves in the erect position from dorsal decubitus [6]. Two cardiovascular complications were reported in the literature. First, an asystolic cardiac arrest in an 18-year-old woman during the second side (left) of bilateral sympathectomy for severe hyperhidrosis, requiring resuscitation maneuvers, with no chronic sequelae [7]. The second case was reported in a 23-year-old woman in whom a bilateral T₂ sympathectomy was performed for facial hyperhidrosis. Two years later, following electrophysiologic studies confirming unopposed vagotonic stimulation, she underwent permanent pacemaker insertion for symptomatic bradycardia [8].

HAZARDS ASSOCIATED WITH CERVICO-THORACIC SYMPATHECTOMY

The need for a realistic appraisal of the potentialities for harm in Cervico-Thoracic sympathectomy is apparent on anatomic grounds alone (Orkin et al. ] 950). Fatalities occur from time to time, but only a few reports of such fatalities find their way into the literature (Adriani et al. 1952). Reported complications associated with Ccrvico-Thoracic sympathectomy, which is, in effect a permanent Stellate
Ganglion block (Moore 1954), include pneumothorax, Horner's syndrome, phrenic and recurrent laryngeal nerve damage, infection from oesophageal puncture, cardiac arrhythmias (Tochinai 1974), and very infrequently cardiac arrest (Moore 1954).
The following is a case report of a healthy 18-year-old woman who had bilateral Cervico-Thoracic sympathectomy done in two stages for severe hyperhidrosis in the palms of her hands.
Two episodes of asystolic arrest occurred during the 2nd stage left Cervico-Thoracic sympathectomy.
The
cause of hyperhidrosis apparently originates
from some poorly understood stimulation of the
sympathetic nervous system (Cloward 1969),
and in sensitive patients this may possibly lead
to excessive vagal stimulation to counteract it,
as illustrated by the bradycardia and asystolic
reaction to the sudden removal of the
sympathetic control, and by the high doses of
sympathomimetic drugs necessary to
recommence cardiac activity. Anatomically the
heart is innervated by the cardiac plexus which
consists of the cardiac nerves derived from the
cervical and upper thoracic ganglia of the
sympathetic trunk and branches of the vagus.
The pacemaker of the heart, the sino-atrial
node, is innervated by both the parasympathetic
and sympathetic nerves (King and Coakley
1958). The ventricular muscle of the heart is
supplied solely by the sympathetic nerves, and
the larger branches of the coronary arteries are
also predominantly innervated by sympathetics
(Woollard 1926). These factors may also have a
bearing on the hazard of a bilateral cervico-
thoracic sympathectomy, which leaves the heart
solely under vagal control. Usually, following
denervation, the heart will initiate its own
impulse, without recourse to external agencies,
but there may be a place for transvenous
electrode cardiac pacing, if spontaneous initiation
of impulse is delayed, or bradycardia is severe.

'Improved sympathectomy' - is it an oxymoron?

"also it seems like the more bad and negative affects were from 10 to 12 years ago when they had just started performing the surgery.. they must have inproved it alot by now.?"

I'd like to echo what some others have said just so you are completely clear on this issue. This procedure has been performed since the 1920's. Yes, the 1920's. In the 1980's they started to do it using "keyhole" surgery which means they don't have to make a big incision. But, the surgery is no different than what they've been doing for the last 70+ years. It's a nerve injury. You can't "improve" they way you inflict a nerve injury. You can't injure the nerve in some "special" way such that the injury suddenly has a different effect on the body.

The functional name for the this surgery is "sympathetic denervation". It's not some super-advanced, modern cure based on recent discoveries in neurophysiology. It's a primitive, destructive procedure. It's a method used on animals for research. It's brute force method...destroy the pathways to the sweat glands over a large region. Unfortunately, it destroys pathways to and from many other organs including the heart and lungs and causes a large number of neuropathological dysfunction. That hasn't changed in the last ten years. It will not and cannot change in the next 1000 years because it will still be a nerve injury 1000 years from now. I'm not making this up. It's a simple fact. Don't let some doctor take advantage of your ignorance

There is no evidence whatsoever that the sympathetic ganglia have any regulatory function on sweating

There is no "signal that tells the body to sweat excessively". The nervous system doesn't work like that. Worse, it implies that there is some separate signal that tells the body to sweat "normally" which, again, is implied to be unaffected by the surgery. It's nonsense and an affront to all that is known about neuroanatomy and neurophysiology.

Of all the lies and distortions, this is the one that pisses me off the most. Not only is it demonstrably false, it is criminally misleading in terms of what it leads the patient to expect. There no evidence whatsoever that the sympathetic ganglia have any regulatory function. Regulation if sympathetic activity occurs in the brain, not the sympathetic ganglia.

Why the hell don't they call it what it is?: sympathetic denervation surgery (which is a fancy name for a particular type of nerve injury). It eliminates excessive sweating by eliminating the ability to sweat at all (anhidrosis) over a large area. It achieves this end in the most brutal way possible: by permanently destroying the neural pathways. Any statement or implication that sympathectomy reduces sweating to normal levels or improves the regulation of sweating in any way is a boldfaced lie.

So numerous are the possible variations that the outcome of a sympathectomy is unpredictable

The sympathetic pathways to the heart are extremely variable in their topography, and the diversity of arrangements encountered accounts for the morphological contradictions in the literature. So numerous are the possible variations that the outcome of a sympathectomy is unpredictable. Where denervation is incomplete, collateral sprouting and regeneration of nerves could even lead to hyperstimulation via the sympathetic pathways.

sympathectomy created imbalance of autonomic activity and functional changes of the intrathoracic organs

Surgical thoracic sympathectomy such as ESD (endoscopic thoracic sympathectic denervation) or heart transplantation can result in an imbalance between the sympathetic and parasympathetic activities and result in functional changes
in the intrathoracic organs.
Therefore, the procedures affecting sympathetic nerve functions, such as epidural anesthesia, ESD, and heart transplantation, may cause an imbalance between sympathetic and parasympathetic activities (1, 6, 16, 17). Recently, it has been reported that ESD results in functional changes of the intrathoracic organs.


In conclusion, our study demonstrated that ESD adversely affected lung function early after surgery and the BHR was affected by an imbalance of autonomic activity created by bilateral ESD in patients with primary focal hyperhidrosis.

Low HRV is a risk factor for pathophysiology and psychopathology

The intimate connection between the brain and the heart was enunciated by Claude Bernard over 150 years ago. In our neurovisceral integration model we have tried to build on this pioneering work. In the present paper we further elaborate our model. Specifically we review recent neuroanatomical studies that implicate inhibitory GABAergic pathways from the prefrontal cortex to the amygdala and additional inhibitory pathways between the amygdala and the sympathetic and parasympathetic medullary output neurons that modulate heart rate and thus heart rate variability. We propose that the default response to uncertainty is the threat response and may be related to the well known negativity bias. We next review the evidence on the role of vagally mediated heart rate variability (HRV) in the regulation of physiological, affective, and cognitive processes. Low HRV is a risk factor for pathophysiology and psychopathology. Finally we review recent work on the genetics of HRV and suggest that low HRV may be an endophenotype for a broad range of dysfunctions.

Fundamentals of psychoneuroimmunology

The long-held concept that the nervous, endocrine and immune systems are separate entities has given way to a new understanding of human biology. Psychoneuroimmunology addresses the realisation that the neural, immune, and endocrine systems are inextricably linked and that the effects of each affect all-the systems work together as a complicated set of triggers and balances, an intertwining of the physiological and emotional states. Beginning with the fundamentals of immune and neuroendocrine function, Fundamentals of Psychoneuroimmunology explores the complexities of behavioural assessment, the basic types of immunity, the importance of immune cell redistribution in the response to challenges such as infection and stress, and the multifaceted roles of nerves, hormones and cytokines.

"Doctors knock controversial sweating treatment; Surgical procedure leaves many people dripping wet on other parts of the body."

(March 2005) The Canadian news magazine "Macleans" reaches nearly 3 million readers every week. In early March, this publication ran a story about the risks of severe compensatory sweating after endoscopic thoracic sympathectomy (ETS) surgery for the treatment of hyperhidrosis. The story's headline read, "Doctors knock controversial sweating treatment; Surgical procedure leaves many people dripping wet on other parts of the body." (Editor's note: As of July 2007, this article was no longer available free online. You may, however, purchase the March 2005 edition of Macleans by visiting
this link.)
According to the article, the most common problem following ETS is increased and profuse sweating on other parts of the body, most often the back, legs, groin, and abdomen. This compensatory sweating, reports Macleans, can be mild to severe and occurs in 80 to 90 percent of patients. In one study of people who had surgery for excessive underarm sweating, 90 percent of the patients reported compensatory sweating and half of them were forced to change their clothes during the day because of it.

In related news, major news outlets (including "The New York Times") have reported this week on a massive insurance scam in the US in which thousands of patients from 40 states had been transported to California to undergo unnecessary surgical and diagnostic procedures. Insurers and employers have lost US $350 million in claims paid to date due to the illegal operations.

As part of the scheme, patients traveled to outpatient surgery clinics in California to receive three or more procedures in a single week. Among the procedures unnecessarily performed on these patients, according to The New York Times, was "...a highly unusual procedure to treat 'sweaty palms.'" The paper quoted an expert who said this particular surgery "posed potential risks to the patient because it involved collapsing the patient's lungs and deactiviating a nerve near the spine."

In return for undergoing unnecessary colonoscopies, endoscopies, and surgeries for "sweaty palms", participating patients were paid anywhere from $200 to $2,000 each and may have received discounts on cosmetic surgery.

ganglion block for unbalanced sympathetic nervous system disorders

Stellate ganglion blocks (SGB) are widely used for pain relief in outpatient clinics due to its many therapeutic indications and easy maneuvering. It is used locally over stellate ganglion territory disorders in the craniocervical (head and neck) or upper limbs and systemically for angina pectoris, psychosomatic disorders, hormonal disorders, or unbalanced sympathetic nervous system disorders [1].

Sympathectomy decreased NE and DA concentrations of muscles to approximately 10% of control values

We studied the effect of unilateral sympathectomy on rat quadriceps and gastrocnemius muscle concentrations of endogenous dihydroxyphenylalanine (DOPA), dopamine (DA), and norepinephrine (NE) and assessed the relationships between these catecholamines in several rat tissues. Catecholamines were measured by reverse-phase high-performance liquid chromatography with electrochemical detection. Sympathectomy decreased NE and DA concentrations of muscles to approximately 10% of control values, whereas the DOPA concentration tended to increase. Relatively high concentrations of DOPA were found in the gastrointestinal tract, kidney, and spleen. No correlations were obtained between the tissue concentration of DOPA and NE. A DA-to-NE ratio approximately 1% was observed in liver, muscle, pancreas, spleen, and heart, whereas we found exponentially increasing DA values with increasing NE concentration in tissues obtained from stomach, small and large intestine, kidney, and lung. In conclusion, endogenous DOPA in muscle tissue is not located in sympathetic nerve terminals but probably in muscle cells. DA concentrations in the gastrointestinal tract and in the kidneys were greater than could be ascribed to its role as a precursor in the biosynthesis of NE.

painful vasospastic condition in the right arm following surgical sympathectomy on the left side

Spinal dorsal column stimulation has been used in the treatment of a patient with a painful vasospastic condition in the right arm following surgical sympathectomy on the left side. After sympathectomy the left arm became constantly dry and warm and consistently lacked skin vasomotor (laser Doppler flowmetry) responses to arousing stimuli, indicating a complete loss of sympathetic vasomotor innervation.

stellate ganglion block in the treatment of panic/anxiety symptoms

Both patients experienced immediate, significant and durable relief as measured by the PCL (score minimum 17, maximum 85). In both instances, the pre-treatment score suggested a PTSD diagnosis whereas the post-treatment scores did not. One patient requested repeat treatment after 3 months, and the post-treatment score remained below the PTSD cutoff after 7 additional months of follow-up. Both patients discontinued all antidepressant and antipsychotic medications while maintaining their improved PCL score.

CONCLUSION:

Selective blockade of the right stellate ganglion at C6 level is a safe and minimally invasive procedure that may provide durable relief from PTSD symptoms, allowing the safe discontinuation of psychiatric medications.

Stellate ganglion block "reboots" the insular cortex

The following is a summary from our publications in Lancet Oncology and Medical Hypothesis

The picture demonstrates the connections from the stellate ganglion to other neural structures.  This was demonstrated using retro rabies virus techniques and functional MRI.  Both are objective data demonstrating the effect on the insula by the stellate ganglion.  Stellate ganglion block effectively "reboots" the insular cortex, allowing for a reduction in hot flashes

The stellate ganglion refers to the ganglion formed by the fusion of the inferior cervical and the first thoracic ganglion as they meet anterior to the vertebral body of C7. It is present in 80% of subjects. It usually lies on or above the neck of the first rib. http://dardipainclinic.com/stellate_ganglion_block.php

To date, sufficient importance has not been placed on the long term effects that could cause dorsal sympathectomy

A scientific society has been created for surgery of the sympathetic nervous system, the International Society of Sympathetic Surgery (ISSS); and in the most recent thoracic surgery and related specialities congresses it fills up a considerable percentage of the programme.
On the other hand, this surgery, especially for hyperhidrosis and facial reddening, is the one that on a percentage basis generates more demands and complaints from the patients, even with medico-legal connotations.7 Despite that the majority of the patients show a very high degree of satisfaction, the presence of a patient operated for hyperhidrosis with important compensatory sweating that repeatedly manifest their dissatisfaction to the surgeon is a very annoying situation with an intractable solution. There are even forums on the Internet that constantly manifest their discomfort with this type of surgery in a violent and insulting tone, for example, the World Against Sympathectomy Website.

In summary, we are faced with a new disorder that is being attended massively in our hospitals and needs a moment of contemplation. What are we doing? Are we doing it properly? What are the future implications in these patients of dorsal sympathetic denervation? For the first 2 questions, we could find the answer in the new clinical guidelines and scientific society norms and with the publication of linger series, randomised systematic studies, reviews and meta-analyses. However, it is perhaps the latter of these that implies greater consideration. To date, sufficient importance has not been placed on the long term effects that could cause dorsal sympathectomy, and the effects on lung function, heart function, skin colouring and psychological state are being studies, among others;10 the most important being the first 2. secondary consequences of the operation.

The consequences of sympathetic denervation after a dorsal sympathectomy on lung function have been studied on several occasions11 and reductions in forced vital capacity, forced expiratory flow in the first second and maximum mesoexpiratory flow have been found, but with no clinical significance. It therefore seems that, despite sympathetic innervation being scarce, it directly influences motor tone, especially of the fine respiratory tracts, which cause a light obstructive pattern after the operation and favours bronchial hyperreactivity.12 It is of great interest to know the results of the research being carried out to recognise the long term effects.
Something similar occurs with heart function, the sympathectomy in the short term causes bradycardia due to a lack of sympathetic stimulation to the heart. Several cases of myocardial infarction13 and
chronotropic heart failure requiring the insertion of a pacemaker14 have been reported. In the long term, dorsal sympathetic interruption causes an effect similar to beta blockers on the heart, and produced a decrease in average heart rate, but with no significant changes in the electrocardiogram (normal Q-T).15 It may be good to know through long term prospective studies which effects it truly has on heart function and what it could mean for the daily lives of the operated patients. For the time being, those individuals who practice aerobic sports (for example, long distance runners and cyclists)
should be informed that with sympathectomy their heart rate may be reduced in situations of maximum effort and lower their performance.16

ETS story

I had ETS surgery (cutting of T2) about 10 years ago for facial HH. The surgery worked very well and I had virtually no immediate complications from the surgery (infection, nerve damage, etc). I now experience severe CS on my trunk (worse on my back) that is pretty debilitating. At this point I'm considering reversal surgery (and am very open to any insight).

I had the surgery done in San Francisco, CA by a now-retired thoracic surgeon (I live in the Portland, OR area). He did mention CS as a possible side effect but didn't present it as a huge risk. To be fair, I was so desperate that I probably wouldn't have listened anyway. That's why it is incumbent on doctors to save us from ourselves. Any surgeon that performs invasive, irreversible surgery to treat conditions where patients are despondent and vulnerable should overemphaasize the risks and minimize the possible benefits (under-promise and over-deliver).

The surgery was uneventful and recovery was quick and I had no immediate complications. In terms of efficacy, the surgery was tremendously successful. My facial HH was immediately and completely resolved, as was my hand-sweating (which wasn't a huge problem, but they are 100% dry now). I still experience gustatory sweating occasionally with very rich or spicy foods but it's not a problem at all. I also still experience blushing but I believe it may be better than it was.

That's the good part. Like many others, I now have severe CS on my trunk (worse on my back). I don't have any of the other dry scalp or pain syndromes that others have though, so maybe I'm one of the lucky ones.

Interestingly, having no moisture on your hands does cause some problems. It's hard to count out money (seriously) or pick things up and it's almost impossible to deal cards (and I used to be a BJ dealer in Las Vegas in college!). It's also hard to play basketball as you really need a little moisture on your hands to properly grip and put spin on the ball.

I've tried hyoscyamine and Robinul and find that Robinul seems to work better but really only reduces the CS about 20-30% most of the time. Often, it doesn't matter what I take.

acute response to surgical denervation and abrupt release of sympathetic tone

Intraoperative predictability of successful outcome depends on monitoring of the acute response to surgical denervation and abrupt release of sympathetic tone.

Information on the long-term physiological sequelae is emerging rapidly. Preoperatively, in addition to abnormal sudomotor control, sympathetic cardiovascular regulation may be affected mildly in severe cases of hyperhidrosis. A blunted reflex bradycardia response to parasympathomimetic maneuvers such as Valsalva maneuver or cold water face immersion, as well as an increased heart rate response
to orthostatic stress, suggests a hyperfunctioning sympathetic discharge that is reversed after ETS.25,69 Because sympathetic cardiac accelerator fibers exit the spinal cord from segments T1 to T4, ETS is believed to simulate a mild physiological !-adrenergic blockade.70 This is because the heart rate at rest and during maximal exercise is lower 6 weeks postoperatively

Surgical Sympathectomy should be first line treatment according to 'Center for the Cure of Sweaty Palms™' surgeon

Given the clear superiority of BTS (bilateral thoracoscopic sympathectomy) for severe palmoplantar hyperhidrosis, deliberately using medical treatments that are known with near certainty to be eneffective and at times considerably noxious simply as a requisite to surgery may not be in the best interest of such patients, nor is such an approach ultimately cost-effective. There is no evidence that surgical intervention should be considered a "last resort" for this form of hyperhidrosis. BTS can safely and confidently be recommended as first-line treatment for the typical, severe form of palmoplantar hyperhidrosis.

Newer techniques include the use of clips instead of complete transsection of the nerve but reversal is not always possible as nerve destruction can be quick and compensatory disease may not be immediate.

This injures all the neurons at this level of the spinal cord, some of which may die, and may predispose the patient to spinal cord reorganization and severe compensatory hyperhidrosis

Sympathectomy vs sympathotomy. Sympathectomy, with use of ganglionectomy and by definition, must sever the primary axon from the neuron in the intermediolateral cell column of the spinal cord (red) before primary or collateral synapse in the T2 ganglion. This injures all the neurons at this level of the spinal cord, some of which may die, and may predispose the patient to spinal cord reorganization and severe compensatory hyperhidrosis. Sympathotomy interrupts only axons after potential T2 ganglion synapses, a less injurious effect on the neuron, and is the least destructive procedure possible with successful treatment
of palmar hyperhidrosis.

reduction in hypothalamic dopamine after sympathecomy, which leads to an increase in serum prolactin level

At this point, it is particularly interesting to recall the earlier reports of middle ear bone remodeling in the gerbil after chemical sympathectomy by guanethidine sulfate (86) or hydroxydopamine (85). Although these neurotoxins do eliminate sympathetic activity, there are, in parallel, major central consequences. In particular, both treatments reduce hypothalamic dopamine, which leads to an increase in serum prolactin levels.

Arch Gen Psychiatry, Nov 1978; 35: 1291 - 1301.

Body temperature is highly correlated with plasma prolactin in thermally stressed men
(78), suggesting that normal heat defense is associated with decreased central dopamine, and
intraventricular haloperidol produces a coordinated heat-defense response (79). These reports refute a
unique or essential role for central dopamine antagonism in neuroleptic malignant syndrome hyperthermia and provide additional evidence that state-dependent factors are important mediators of dopamine antagonist effects.
There is substantial evidence to support the hypothesis that dysregulated sympathetic nervous system hyperactivity is responsible for most, if not all, features of neuroleptic malignant syndrome. A predisposition to more extreme sympathetic nervous system activation and/or dysfunction in response to emotional or psychological stress may constitute a trait vulnerability for neuroleptic malignant syndrome, which, when coupled with state variables such as acute psychic distress or dopamine receptor antagonism, produces the clinical syndrome of neuroleptic malignant syndrome. This hypothesis provides a more comprehensive explanation for existing clinical data than do the current alternatives.

Intentional misrepresentation of the elective surgical sympathectomy is common practice

"Sweating is one form of regulating the body's temperature. If the operation prevents sweating in one area, it is possible that patients will notice a greater amount of sweating elsewhere in their body in order to compensate. This is called "compensatory sweating" and can occur on the face, abdomen, back, buttocks, thighs, or feet. While this is a mild nuisance for most patients, occasionally (5-10% of the time) it can be severe and interfere with the patient's lifestyle. If it occurs, it usually improves within 6 months."
http://thoracic.surgery.virginia.edu/general-thoracic/general-thoracic-conditions-treatment/hyperhidrosis/


Mia: None of the 'facts' listed in the above text can be supported by scientific evidence. The information illustrates the myths spread on the internet by those who have a financial interest in offering ETS, - an interest that overrides the medical and ethical obligations of the medical profession. 
The so called "compensatory sweating" is NOT compensatory, and the only study looking into  this concluded that patients did sweat more after ETS. 
If this side-effect  of the elective surgery (intentional neurological injury/lesion) would be "compensatory" in order to maintain thermoregulation, it would be observed after botox or ionthoporesis treatment as well. Hyperhidrosis (reflex hyperhidrosis)  is an usual finding in people after spinal cord injuries (especially above T6) and in diabetics due to damage to the SNS. It is a pathological response to injury.

 No evidence can support - and there is clear contrary evidence -   that if this compensatory sweating would occur, it would diminish in 6 months. It is all part of the intentional misrepresentation of elective surgeries to make them appear more appealing and safer than they are.

Extreme caution is called for when considering surgical sympathectomy

Surgical sympathectomy is carried out on the basis of poor quality evidence, studies without
control groups, and personal experience. Though it would appear logical (and has been
suggested) that surgical sympathectomy is indicated primarily for patients with confirmed
'sympathetic-dependent pain, other authors take the view that the treatment results are
not correlated to this. Eighteen percent of patients undergoing sympathectomy for
neuropathic pain experience compensatory hyperhidrosis and 25% experience neuropathic
complications.
Extreme caution is called for when considering surgical sympathectomy for pain control in
CRPS-I. The procedure should be conducted in the context of a trial in order to ascertain
the efficacy and potential risks.

lumbar sympathectomy results in loss of ejaculation

Sympathectomy for the long term management of such patients has been carried out (Abel et al., 1974) and success reported. Loss of ejaculation does follow sympathectomy but his is a minor problem in patients who have an already destroyed sacral cord. (p. 410)

During fever pyrogen is released from leucocytes and his agent causes the disturbed thermoregulation (Atkinson, 1960). For his response to occur, an intact efferent sympathetic system is requred because fever can be markedly reduced by bilateral sympathectomy in he cat (Pinkston, 1935). (p.193)

Informed consent - sympathectomy

Physicians are required to gain informed consent prior to administering a treatment. Informed consent is gained by providing patients with a full accounting of the risks of the treatment as documented in peer-reviewed, published medical/scientific literature.

Your scenario of surgeons being flummoxed by unhappy patients complaining after surgery doesn't hold water. The rules of professional medical ethics require that the treating physician be well versed in the published literature on the treatments he delivers.

There is a mountain of published research (spanning nearly a century) documenting the adverse effects of sympathectomy. There are numerous studies, for example, showing very high rates of severe side effects and studies showing that satisfaction diminishes substantially over the long term.
It is a doctors job to know this stuff and it is their ethical duty to disclose that information to patients.
So, I see the blame thing as pretty cut and dry. Surgeons perfoming sympathectomies routinely withhold information vital to informed consent. Anyone who does objective comparison between what is documented in medical/scientific literature and what is typically disclosed to prospective ETS patients has no choice but reach this conclusion.

And, to make matters worse, many surgeons use testimonials from a hand-selected group of their happiest patients to advocate the surgery. That practice is considered unethical by all medical professional organizations.

These data suggest that induction of a prolonged state of mechanical hyperalgesia causes time-dependent alterations in the sympathetic control of peripheral nociceptive mechanisms such that sympathectomy can lead to enhanced hyperalgesic response. These findings may be relevant to post-sympathectomy pain, a clinical entity for which there has been no available animal models.

Serious complications reported after sympathectomy

Surgery involving the clamping of sympathetic nerve trunks to prevent excessive perspiration and blushing appears to be of questionable value.

Complications have been reported, ranging from phantom perspiration to blood clots in the brain.

The Finnish Office for Health Care Technology Assessment (FinOHTA), which is part of the National Research and Development Centre for Welfare and Health (STAKES) recently conducted a survey on the various effects of hyperhidrosis surgery at the request of the Finnish Medical Association.

Finnish surgeon Timo Telaranta has performed about 2,000 such operations at private clinics in Helsinki and Oulu in the past ten years.
The National Authority for Medicolegal Affairs has issued three warnings to Telaranta and the Provincial Government of Southern Finland has issued one.
There are currently no complaints pending against Telaranta, and the authority has not considered restricting his rights to practice medicine.

The Finnish Patient Insurance Centre has processed 20 complaints concerning Telarantas Privatex clinic. The complaints resulted in 14 decisions to pay compensation. All except two of the surgeries were conducted by Telaranta himself.
Telaranta says that he treats patients suffering from difficult social anxiety with endoscopic surgery in which an incision is made into the upper part of the chest cavity, and the sympathetic nerve trunk is severed or clamped.
Most patients are satisfied with the treatment. However, FinOHTA found that there were many negative side-effects, some of which were very serious.
With most patients, heavy perspiration of the palms has moved to other parts of the body, below the breasts. As many as 15% of those who have undergone the surgery said that the surge in body perspiration forces them to change underwear several times a day.
Other side-effects have included drying of the skin on the face and hands, as well as perspiration triggered by eating spicy food. There are also reports of phantom perspiration - the feeling of perspiration when none takes place - as well as a weakened tolerance for cold.

More serious effects include collapsing of a lung, breathing difficulties, and blood clots in the brain. Some patients got a hanging eyelid, while others reported a sudden raspiness of their voice.
One of Dr. Telarantas patients who had made a complaint began to experience strong reactions of anxiety which did not go away even after corrective surgery. Later the patient committed suicide.

Dr. Telaranta himself says that the side-effects are regrettable. However, he says that he has developed a procedure which does not cause any such side effects.
He also says that it is important to examine patients carefully, and to perform surgery only on those who are suited for the procedure.
Many doctors have serious reservations about the idea of treating complaints such as excessive perspiration, blushing, and performance anxiety by severing peoples nerves.

decreased conditioning-related activity in insula and amygdala in patients with autonomic denervation

The degree to which perceptual awareness of threat stimuli and bodily states of arousal modulates neural activity associated with fear conditioning is unknown. We used functional magnetic neuroimaging (fMRI) to study healthy subjects and patients with peripheral autonomic denervation to examine how the expression of conditioning-related activity is modulated by stimulus awareness and autonomic arousal. In controls, enhanced amygdala activity was evident during conditioning to both "seen" (unmasked) and "unseen" (backward masked) stimuli, whereas insula activity was modulated by perceptual awareness of a threat stimulus. Absent peripheral autonomic arousal, in patients with autonomic denervation, was associated with decreased conditioning-related activity in insula and amygdala. The findings indicate that the expression of conditioning-related neural activity is modulated by both awareness and representations of bodily states of autonomic arousal.

Effect of sympathectomy on mechanical properties of common carotid and femoral arteries

Compared with the intact animals, sympathectomized rats showed a marked increase in arterial distensibility over the entire systolic-diastolic pressure range. When quantified by the area under the distensibility-pressure curve, the increase was 59% and 62% for the common carotid and femoral arteries, respectively (P<.01 for both). In the femoral but not in the common carotid artery, sympathectomy was accompanied also by an increase in arterial diameter (+18%, P<.05 versus intact). Therefore, in the anesthetized normotensive rat, sympathetic activity exerts a tonic restraint on large-artery distensibility. This restraint is pronounced in elastic vessels and even more pronounced in muscle-type vessels.

endoscopic sympathicotomy in carotid and vertebral arteries in the surgical treatment of primary hyperhidrosis

Analyze, in patients with primary hyperhidrosis (PH) who was undergone to videothoracoscopic sympathicotomy, the degree of vascular denervation after surgical transection of the thoracic sympathetic chain by measuring ultrasonografic parameters in carotid and vertebral arteries.

METHODS:

Twenty-four patients with PH underwent forty-eight endoscopic thoracic sympathicotomy and were evaluated by duplex eco-Doppler measuring systolic peak velocity (SPV), diastolic peak velocity (DPV), pulsatility index (PI) and resistivity index (RI) in bilateral common, internal and external carotids, besides bilateral vertebral arteries. The exams were performed before operations and a month later. Wilcoxon test was used to analyse the differences between the variables before and after the sympatholisis.

RESULTS:

T3 sympathicotomy segment was the most frequent transection done (95.83%), as only ablation (25%) or in association with T4 (62.50%) or with T2 (8.33%). It was observed increase in RI and PI of the common carotid artery (p < 0.05). The DPV of internal carotid artery decreased in both sides (p < 0.05). The SPV and the DPV of the right and left vertebral arteries also increased (p < 0.05). Asymmetric findings were observed so that, arteries of the right side were the most frequently affected.

CONCLUSIONS:

Hemodynamic changes in vertebral and carotid arteries were observed after sympathicotomy for PH. SPV was the most often altered parameter, mostly in the right side arteries, meaning significant asymmetric changes in carotid and vertebral vessels. Therefore, the research findings deserve further investigations to observe if they have clinical inferences.

most experts do not recommend ETS for the treatment of hyperhidrosis

sweating from these areas could be under cortical control, separate from the hypothalamic centers involved in thermoregulation

Compensatory hyperhidrosis is excessive sweating of the abdomen, chest, back, thighs, and face,[6,72] usually in response to increased temperature.[46] This is the most common complication following ETS, reported to occur at an average rate of about 60%, with a range of 3% to 98%.[46] Higher rates have been reported from countries with warmer climates, such as in Asia and the Middle East.[46,82] The sweating can be severe for 10% to 40% of patients.[10] Although it has been written that compensatory sweating diminishes with time, several series have documented continued symptoms with longer-term follow-up.[46] In one series of 270 patients followed for a mean of 15 years postsympathectomy, 67% still complained of compensatory sweating, and overall satisfaction fell from an initial level of 96% to 67%.[55] It is possible that patients begin to notice compensatory sweating some time after ETS, as they are initially more aware of the marked reduction of their primary hyperhidrosis.[46] The mechanism for compensatory sweating is unclear; the most likely explanation is that sweating in the trunk increases to compensate for the lack of sweating from the denervated areas in order to maintain thermoregulation.[82] The occurrence of decreased sweating in other areas not innervated by the ganglia treated by ETS suggests that the response to ETS is more complex. The soles are the most common area with decreased sweating post-ETS, and, along with the axillae and palms, sweating from these areas could be under cortical control, separate from the hypothalamic centers involved in thermoregulation.[72] It has also been proposed that ganglion destruction affects axons of neurons in the interomediolateral spinal cord, which could lead to cell death or re-organization, changing the control of the sympathetic system by the spinal cord and higher, leading to increased sympathetic tone in the other body areas not treated by ETS.[10]  http://www.sweathelp.org/English/HCP_Treatment_ETS_Surgery_Complications.asp?printfriendly=true

the decrease in CBF induced by chronic sympathectomy cannot be attributed to the development of hypersensitivity

Thus the decrease in CBF induced by chronic sympathectomy cannot be attributed to the development of hypersensitivity to catecholamines. This decrease remained stable whatever the value of resting flow and was maintained under anesthesia. It is concluded that, as in the peripheral circulation, chronic sympathectomy affects the equilibrium of the vascular smooth muscle fibers, but that circulating amines play no compensatory role in the cerebral circulation because of the blood-brain barrier.

Sympathectomy - a surgically induced neuropathy

"Vascular and neural diseases are closely related and intertwined. Blood vessels depend on normal nerve function, and nerves depend on adequate blood flow. The first pathological change in the microvasculature is vasoconstriction. As the disease progresses, neuronal dysfunction correlates closely with the development of vascular abnormalities, such as capillary basement membrane thickening and endothelial hyperplasia, which contribute to diminished oxygen tension and hypoxia."

Sympathectomy results in vascular abnormalities, loss of vasoconstriction, capillary basement thickening and endothelial hyperplasia...

oedema associated with the interruption of preganglionic sympathetic tract

Swelling and oedema is often observed in patients with Raynaud's disease or causalgia after acute interruption of post-ganglionic sympathetic fibres such as a wide-spread sympathectomy. Complete sympathetic 

block dilates vein and capillary and increases peripheral pooling, which raises hydrostatic the shins and feet (fig 2), constipation and 

abdominal distention, and dysuria were observed. Oedema was not noted in the 

hands or face. 

 There were no signs or abnormal laboratory data suggesting heart failure, renal failure, liver dysfunction, thyroid dysfunction or local inflammation. Venography of the left leg did not show obstruction in the deep veins. 

 We showed that the preganglionic sympathetic tract in the spinal cord was often 

disturbed in patients with multiple sclerosis with myelopathy.' Most patients with com- 

plete transection of the spinal cord due to injury showed swelling of the lower limbs or 

oedema, but they gradually subsided within several months even without restoration of 

somatic function. Probably some compensatory mechanism improves the hydrostatic 

condition in the chronic stage and explains why oedema is not noted in patients with 

chronic autonomic failure syndrome.
