The vasodilating effect of spinal dorsal column stimulation is mediated by sympathetic nerves - Springer

The vasodilating effect of spinal dorsal column stimulation is mediated by sympathetic nerves - Springer: "Immediately after sympathectomy, the contralateral right arm became increasingly cold and cyanotic and the patient complained of chronic painful coldness and severe cold-intolerance in the right arm. Attempts to pharmacologically vasodilate the arm with felodipine did not affect the local vasoconstriction and pain. Dorsal column stimulation (associated with symmetrical paraesthesia in both arms) induced an immediate and marked (ten-fold) increase in skin blood flow in the right arm (and in the leg), whereas skin blood flow in the left arm remained unaffected. The lack of vasomotor response in the left arm was not due to maximal vasodilatation at rest, since skin blood flow in the left arm showed a normal capacity for axon reflex vasodilatation following antidromic activation of sensory afferents. The results suggest that the marked vasodilatation induced by dorsal column stimulation is mediated by sympathetic vasomotor fibres, via modulation of central neuronal circuits involved in the regulation of skin sympathetic discharge."

catecholamine released from sympathetic nerves, acquires the capacity to activate pain pathways after tissue or nerve injury

What Is Reflex Sympathetic Dystrophy Syndrome or RSD?: "According to the National Institute of Neurological Disorders and Stroke (NINDS), RSD is "a chronic pain condition that is believed to be the result of dysfunction in the central or peripheral nervous systems." According to MedicineNet, RSD involves "irritation and abnormal excitation of nervous tissue, leading to abnormal impulses along nerves that affect blood vessels and skin."

Animal studies indicate that norepinephrine, a catecholamine released from sympathetic nerves, acquires the capacity to activate pain pathways after tissue or nerve injury, resulting in RSD. Another theory suggests that RSD, which follows an injury, is caused by triggering an immune response and symptoms associated with inflammation"

Transection below T8-T10 is not accompanied by reflex sweating

Reflex sweating in patients with spina... [Arch Phys Med Rehabil. 1977] - PubMed - NCBI: "Sweat glands derive their innervation from the sympathetic nervous system. The spinal sympathetic structures that are located in the intermediolateral areas extend from T1-L2 segments and are under the control of hypothalamic centers. Cord transection abolishes the supraspinal control of sudorimotor function. Since sympathetic innervation does not follow a clear segmental distribution, normal sweating may be preserved at a higher or lower level than skin sensation. Nonthermoregulatory reflex sweating is an indication of unchecked spinal cord facilitation and is precipitated by afferent stimuli from bladder, rectum, and various other sources. It is usually a manifestation of mass reflex or autonomic crisis and occurs particularly in cervical or high thoracic lesions. Transection below T8-T10 is not accompanied by reflex sweating. The phenomenon of thermal relfex sweating is controversial. Although some aspects of nonthermoregulatory reflex sweating are still unclear, proper immediate and continuing preventive management will reduce the incidence of this and other autonomic manifestations.

Hemodynamic changes in vertebral and carotid arteries were observed after sympathicotomy for hyperhidrosis



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.

Limited heart rate variability, autonomic nervous system imbalance implicated in the aetiology of CFS


The Conversation: "The stress-response neural systems of chronic fatigue syndrome (CFS) patients remain on high alert even when they sleep, signalling that it’s not safe to relax, researchers have found.

Researchers also discovered that reduced heart rate variability, or changes in heart beat timing, are the best predictors of cognitive disturbances, such as concentration difficulties commonly reported by CFS sufferers. This adds to the growing body of evidence linking autonomic nervous system imbalance to this disorder.

The findings could lead to new ways to improve cognitive difficulties in people with CFS, which remains a poorly understood condition."


ETS result in limited (reduced) heart rate variability and alters the ANS (sympathetic and parasympathetic balance). This article might provide some insight into the cases where ETS resulted in a variety of unwelcome and detrimental side-effects, including fatigue, altered cognitive function ('brain fog'), etc.

No compensatory sweating after botulinum toxin treatment of palmar hyperhidrosis

RESULTS:
Following treatment, palmar evaporation decreased markedly and then returned slowly towards pretreatment values, but was still significantly reduced 6 months after treatment. No significant increase of sweating was found after treatment in any nontreated skin area.
CONCLUSIONS:
Successful treatment of palmar hyperhidrosis with botulinum toxin does not evoke compensatory hyperhidrosis in nontreated skin territories."

Nerve injury can result in chronic pain - sympathectomy is a surgical nerve injury


Blocking sympathetic function, whether by surgical sympathectomy, systemic phentol- amine, or systemic guanethidine, relieves partial nerve injury-induced neuropathic pain in laboratory animal models as well as humans (8, 35, 146, 239, 278). Indeed, sympathectomy does not just relieve pathological pain in the body region ipsilateral to the CRPS-initiating event; rather, it also relieves pain arising from anatomically impossible mirror-image sites, that is, the identical body region contralateral to the initiating event (278). Thus sympathetectomy must somehow quiet the contralateral spread of spinal cord hyperexcitability underlying mirror- image pain.
Alterations in sympathetic fibers rapidly follow pe- ripheral nerve injury. This occurs as sprouting of sympa- thetic fibers, creating aberrant communication pathways from the new sympathetic terminals to sensory neurons (35). Sympathetic sprouting has been documented in the region of peripheral terminal fields of sensory neurons (262), at the site of nerve trauma (57), and within the dorsal root ganglia (DRG) containing cell bodies of sen- sory neurons (248, 343). Each of these sites develops spontaneous activity and sensitivity for catecholamines and sympathetic activation (8, 53).
The clearest evidence that immune activation partic- ipates in sympathetic sprouting comes from studies of the DRG. DRG cells receive signals that peripheral nerve injury has occurred via retrograde axonal transport from the trauma site. These retrogradely transported signals trigger sympathetic nerve sprouting into DRG (205, 308). As a result of nerve damage-induced retrogradely trans- ported signals, glial cells within the DRG (called satellite cells) proliferate (248) and become activated (343); mac- rophages are recruited to the DRG as well (63, 176). In turn, the activated satellite glial cells (and, presumably, the macrophages) release proinflammatory cytokines and a variety of growth factors into the extracellular fluid of the DRG (206, 246–248, 258, 277, 308, 358). These sub- stances stimulate and direct the growth of sympathetic fibers, which form basket-like terminals around the satel- lite cells that, in turn, surround neuronal cell bodies (247, 248, 343). For discussion of satellite cell functions, see section IIIA.

bilateral sympathectomy may cause bowel, bladder, or sexual dysfunction


If regional sympathetic blockade provides relief, surgical sympathectomy can be considered. Initial pain relief may be significant, but symptoms tend to recur over the next 2 to 5 years.[53] This is believed to occur owing to incomplete surgical removal of all sympathetic innervation to the extremity. Collateral reinnervation can occur, but bilateral sympathectomy may cause bowel, bladder, or sexual dysfunction.[14]

It is possible to disrupt the sympathetic chain ganglion by treatments other than surgery. Ablation with radiofrequency devices and caustic chemicals (such as alcohol) have been described, but the region of necrosis may expand beyond the ganglion and long-term results are unknown.[59,][69] As such, surgical sympathectomy is considered strictly as a last resort.

Stellate ganglion block may relieve hot flashes by interrupting the sympathetic nervous system

Stellate ganglion block may relieve hot flash... [Med Hypotheses. 2007] - PubMed - NCBI: "the wide range of conditions that have been reported to respond favorably to stellate ganglion block suggest that its effectiveness may not be solely the result of increased blood flow nor restricted just to its sphere of innervation. We have found that stellate ganglion block is effective in the treatment of hot flashes in postmenopausal women, as well as those with estrogen depletion resulting from breast cancer treatment. Based on evidence that hot flashes may be centrally mediated and that the stellate ganglion has links with the central nervous system nuclei that modulate body temperature, we hypothesize that the stellate ganglion block provides relief of hot flashes by interrupting the central nervous system connections with the sympathetic nervous system, allowing the body's temperature-regulating mechanisms to reset. If this mechanism can be confirmed, this would provide women with intractable hot flashes with an effective, potentially long-lasting means of relieving their symptoms, and potentially widen the range of indications for stellate ganglion block to include other centrally mediated syndromes."

patients with palmar hyperhidrosis have no overactivity of the sympathetic nerve


HR and BP at rest and cardiovascular response to exercise were similar in patients with palmar hyperhidrosis before ETS and in the normal control population. Therefore, we consider that patients with palmar hyperhidrosis have no overactivity of the sympathetic nerve. However, because bilateral ETS causes the suppression of cardiovascular response to exercise, patients that has been treated with ETS need to be observed during high-level exercise.

Post-sympathectomy pain

Postsympathectomy limb pain, postsympathectomy parotid pain, and Raeder's paratrigeminal syndrome are pain states associated with the loss of sympathetic fibres and in particular with postganglionic sympathetic lesions. There is a characteristic interval of about 10 days between surgical sympathectomy and onset of pain. It is proposed that this pain in man is correlated with the delayed rise in sensory neuropeptides seen in rodents after sympathectomy. These chemical changes probably reflect the sprouting of sensory fibres and may result from the greater availability of nerve growth factor after sympathectomy. The balance between the sensory and sympathetic innervations of a peripheral organ may be determined by competition for a limited supply of nerve growth factor.

Another case of disabled thermoregulation and heatstroke following sympathectomy


We describe an extreme case of compensatory truncal hyper- hidrosis and anhidrosis over the head and neck region which led to a heatstroke. 

Six months after the initial operation, he had an episode of heatstroke while perform- ing outdoor duties which required running for around 5 km. The temperature on the day was between 30–32°C, and the relative humidity was between 75 and 85%. At that time, he complained of light-headedness, ‘feeling’ that heat could not dissipate from his head and neck region and muscle cramp in his legs. He was transferred to a hospital and was found to have a body tem- perature of 40°C and shock. His presentation was similar to a previous report by Sihoe et al. [1] on a patient with post- sympathectomy heatstroke. He was subsequently successfully treated with fluid and electrolyte resuscitation and supportive care.

69% of patients continued to have relief after ETS, patient satisfaction rate was 56%


There were no operative mortalities, minor complications occurred in 22%. Initial success rate was 88%. Median follow up was 93 (24-168) months, response rate to the questionnaire was 85%. Sixty-nine per cent of patients continued to have relief of initial symptoms, whereas patient satisfaction rate was 56%. CS was present in 42 patients (68%). Long-term satisfaction rates per initial indication group were 42% for facial blushing and 65% for hyperhidrosis (n.s.), and CS was present in 79% vs 61%, respectively.
CONCLUSION:
ETS appears a safe treatment for upper limb hyperhydrosis with acceptable long-term results. For excessive blushing, however, long-term satifaction rates of ETS are severely hampered by a high incidence of disturbing compensatory sweating. ETS should only be indicated in patients with unbearable symptoms refractory to non-surgical treatment. The patient information must include the long-term substantial risk for sever CS and regret of the procedure.

"sympathectomy highlighted the disparity between what is known in practice and what appears in the literature"


The March 2004 edition was quite outstanding, with an excellent editorial reminding the reader that only good results are published. The review on thoracoscopic sympathectomy highlighted the disparity between what is known in practice and what appears in the literature. 
‘Know Your Results’, the topic of the ASGBI Annual Scientific Meeting, is of outstanding importance; what is more, the surgeon has to go on knowing his/her results to ensure standards of practice do not slip.
The Journal appreciates comments and criticism and the correspondence column remains a crucial part of the BJS in its interaction between editors and reader. It is also part of the scientific process.
A more robust and incisive criticism of articles known to be flawed would prevent the retractions that have recently been published in the Lancet.

Abstract
BACKGROUND: Compensatory sweating (CS) is the main cause of a patient's dissatisfaction after sympathetic surgery for palmar hyperhidrosis.Preservation of the sympathetic nerve trunk and limitations on the range of dissection are necessary to reduce CS.
METHODS: We compared 64 patients (31 male, 33 female) (group 1) who underwent a T2 sympathicotomy between July 1998 and February 1999 and 83 patients (58 male, 25 female) (group 2) who underwent a T3 ramicotomy between August 2000 and December 2002.
RESULTS: In group 1, 60 patients (93.8%) exhibited a decreased sweating on both hands, but 4 patients (6.2%) exhibited a persistent sweating on both hands. For group 2, 58 patients (69.9%) experienced a decreased sweating on both hands, 15 patients (18.1%) experienced a persistent sweating on both hands, and 10 patients (12.0%) experienced a persistent sweating on one hand. The grade of CS in group 2 was significantly lower than in group 1 (p < 0.001) and, notably, the rate of embarrassing and disabling CS in group 2 (15.5% [9 out of 58]) was significantly lower than in group 1 (43.3% [26 out of 60], p value < 0.001). The rate of satisfaction was 78.1% (50 out of 64) for group 1 and 68.6% (57 out of 83) for group 2 with no significant statistical difference indicated (p = 0.202).
CONCLUSIONS: The incidence of sweating postoperatively was relatively high in the T3 ramicotomy group, although the T3 surgery did result in a lower incidence of CS when compared with a T2 sympathicotomy.

Abstract
PURPOSE: Endoscopic thoracic sympathetic surgery is effective for treating palmar hyperhidrosis, although compensatory sweating (CS) is a significant and annoying side effect. The purpose of this study was to compare the results of limited resection at two different locations.
METHODS: From May 2004 to June 2009, T3 sympathicotomy (group I) was performed in 46 patients and T3,4 ramicotomy (group II) was performed in 43 patients during the same period. T3 sympathicotomy (group I) and T3,4 ramicotomy (group II) were performed during the same period. Using questionnaires, completed by the patients, the satisfaction rates and grades of CS were analyzed.
RESULTS: No significant differences in age distribution or sex ratios were observed between the two groups. The satisfaction rate was 91.3 % in group I and 79.1 % in group II. The operation time was 19.8 (±6.6) min (sic!) in group I, and 51.6 (±18.8) min in group II, showing a statistically significant difference (p < 0.002). The incidence of persistent hand sweating in group II (16.3 %) was higher than that observed in group I (2.2 %). The incidence of compensatory sweating on the lower extremities was higher in group II (37.2 %) than in group I (10.9 %).
CONCLUSIONS: Although ramicotomy is considered to be an effective method for treating hyperhidrosis and has a theoretical advantage of allowing greater anatomical resection, it requires longer operation time and induces more severe compensatory sweating in the lower limbs resulting in reduced satisfaction rates.

The effect of bilateral sympathectomy was significantly greater than that of unilateral sympathectomy


The effect of bilateral sympathectomy was significantly greater than that of unilateral sympathectomy. Unilateral and bilateral sympathectomy produced similar reductions in the concentrations of NPY-ir and NA in the ventricular tissue. In contrast dissimilar changes were produced in the atrium. Although bilateral sympathectomy almost totally depleted the NA from the right atrium (by 98%), the NPY-ir levels were only reduced by 50%. These results indicate that approximately half the content of NPY in the right atrium is not present in sympathetic noradrenergic neurones.

sympathectomy induced morphological alterations in the masseter muscles


Sympathectomized animals showed varying degrees of metabolic and morphological alterations, especially 18 months after sympathectomy. The first five groups showed a higher frequency of type I fibres, whilst the oldest group showed a higher frequency of type IIb fibres. In the oldest group, a significant variation in fibre diameter was observed. Many fibres showed small diameter, atrophy, hypertrophy, splitting, and necrosis. Areas with fibrosis were observed. Thus cervical sympathectomy induced morphological alterations in the masseter muscles. These alterations were, in part, similar to both denervation and myopathy. These findings indicate that sympathetic innervation contributes to the maintenance of the morphological and metabolic features of masseter muscle fibres.

Bilateral cervical sympathectomies should be avoided because of the destruction of cardioaccelerator tone

SURGICAL SYMPATHECTOMY ON THE SENSITIVITY TO EPINEPHRINE OF THE BLOOD VESSELS OF MUSCULAR SEGMENTS OF THE LIMBS

Pursuing this study of the effect of epinephrine on muscle blood flow, Duff and Swan (10) reported that during intravenous epinephrine infusions the initial marked dilatation was succeeded by a second phase of moderate dilatation in normal but not in sympathectomized limbs. Because of its absence in chronically sympathectomized limbs this secondary vasodilatation was at that time thought to be an indirect vasomotor effect mediated by the sympathetic nerves. Re-examination of their data in the light of some subsequent critical experiments now reveals that the difference which they found between normal and sympathectomized limbs may be ascribed largely to vascular hypersensitivity in the later.
In the present paper these additional data are reported, and are incorporated with those of Duff and Swan(10); the whole material being interpreted to provide evidence that hypersensitivity of the vessels of skeletal muscle in the upper and lower limbs may result from pre- and postganglionic sympathectomy in man.

Nerve regeneration commonly occurs following both surgical of chemical sympathectomy


Sympathectomy is a destructive procedure that interrupts the sympathetic nervous system. Chemical sympathectomies use alcohol or phenol injections to destroy sympathetic nervous tissue (the so‐called "sympathetic chain" of nerve ganglia). Surgical ablation can be performed by open removal or electrocoagulation (destruction of tissue with high‐frequency electrical current) of the sympathetic chain, or minimally invasive procedures using thermal or laser interruption. 

Nerve regeneration commonly occurs following both surgical of chemical ablation, but may take longer with surgical ablation.

This systematic review found only one small study (20 participants) of good methodological quality, which reported no significant difference between surgical and chemical sympathectomy for relieving neuropathic pain. Potentially serious complications of sympathectomy are well documented in the literature, and one (neuralgia) occurred in this study. 

The practice of sympathectomy for treating neuropathic pain is based on very weak evidence. Furthermore, complications of the procedure may be significant.

Authors' conclusions: The practice of surgical and chemical sympathectomy for neuropathic pain and CRPS is based on very little high quality evidence. Sympathectomy should be used cautiously in clinical practice, in carefully selected patients, and probably only after failure of other treatment options.

Animal studies indicate that norepinephrine, a catecholamine released from sympathetic nerves, acquires the capacity to activate pain pathways after tissue or nerve injury, resulting in RSD.

Management of reflex sweating in spinal cord injured patients

Reflex sweating can be a problem for cervical spinal cord injured patients. Patient comfort and skin breakdown have been the major concerns. Five patients were studied prospectively, using a patch containing 1.5mg of scopolamine. Patches were changed every third day. Each patient was carefully monitored before and after application of the patch for signs and symptoms of anticholinergic side effects such as dizziness, blurred vision and dry mouth. Patients were also monitored for changes in patch signs before and after use, including residual urine volumes, blood pressure, heart rate, and mental status. Our study indicates that topical scopolamine successfully controlled reflex sweating in 5 patients without anticholinergic side effects.

"Caesar judging Caesar" - utterly dysfunctional medical boards

In the end, the state's medical board, two-thirds of which are doctors, allowed the doctor to retain his registration to practise with one condition: he stop working in intensive care.
Ms Barber, who revealed a series of concerns to 7.30 in April about malpractice in Queensland hospitals, says it is a case of "Caesar judging Caesar".
She says the review of such cases should be handled by a panel of people who are "legally minded", with the assistance of medical administrators.
"It's completely and utterly dysfunctional and if you were to look in the last 10 years, those [doctors] that actually had been struck off or completely gotten rid of as a result of their incompetence would be - you could count them on one hand. Maybe five or six," she said.
The allegations have been referred to Queensland's Crime and Misconduct Commission (CMC).
The CMC has appointed a former Supreme Court judge to examine what it calls a series of allegations and has referred material to the homicide squad.
Former MP Rob Messenger, who was instrumental in revealing the deeds of Dr Jayant Patel, says the case needs to go to a commission of inquiry "right now".
"It needs to go from an assessment stage to a full-blown investigation stage, but that investigation won't be effective unless witnesses are given protection," he said.
"And it's only a commission of inquiry that will be able to give potential witnesses the protection and confidence for them to come forward and tell the truth, tell their story."
The medical board declined 7:30's request for interview, but released a statement saying its role is to protect the public but that it must also be fair, lawful and provide natural justice to practitioners.

surgical and chemical sympathectomy can both modulate bone cell function

It is known that surgical and chemical sympathectomy can both modulate bone cell function.  However, the sympathetic
nervous system (SNS) can give rise to both anabolic and catabolic effects [28-31] and its role in regulating bone remodeling is, therefore, controversial. For example, some researches reported that if bone is deprived of its sympathetic innervation, bone
deposition and mineralization is reduced and bone resorption increases [31], while in some other reports a sympathectomy impairs bone resorption [28].

Pain in the form of intercostal neuralgia with dysesthesia at the site of trocar insertion is rarely documented but more frequent than generally recognized

Pain in the form of intercostal neuralgia with dysesthesia at the site of trocar insertion is rarely documented but more frequent than generally recognized. Many centres perform short-stay surgery that may lead to underestimation of pain results. In most series pain resolves within months, but Walles and colleagues could detect a persistence for years (Walles et al., 2008).

left thoracic sympathectomy to prevent electrical storms in CPVT patients

Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT), a life threatening arrhythmia induced by sympathetic stimulation in susceptible individuals is often refractory to antiarrhythmic agents. First line of treatment, beta-blockers can be ineffective in up to 50% with implantable cardioverter-defibrillator (ICD) placement for refractory cases. Paradoxically ICD can be arryhthmogenic from shock-associated sympathetic stimulation, initiating more shocks and "electrical storms". This has led to the use of more effective beta blockade offered by left sympathectomy, now performed by minimally invasive video assisted thoracoscopic surgery (VATS).
To our knowledge this is first such reported case.

Sympathectomy for the treatment of polymorphic ventricular tachycardia

Bilateral thoracoscopic cervical sympathectomy for the treatment of recurrent polymorphic ventricular tachycardia.

Turley AJ, Thambyrajah J, Harcombe AA.
Despite potassium and magnesium supplements, beta blockade, implantation of a single then dual chamber implantable cardioverter defibrillator (ICD), amiodarone, nicorandil, and mexiletine, the patient continued to experience arrhythmia storms, receiving more than 700 ICD discharges over seven months. She was ultimately treated successfully with bilateral thoracoscopic cervicothoracic sympathectomies. This is the first reported bilateral thoracoscopic treatment of a patient with LQTS and symptomatic life threatening ventricular tachyarrhythmias refractory to current pharmacological and pacing techniques.

The Dangers of ETS Surgery for Excessive Sweating

If you have an excessive sweating problem, you may have heard of endoscopic sympathectomy (ETS) surgery. If you are considering this option - Don't!
This surgery can have severe complications and, in spite of the promises, could leave you in a worse situation than you currently face. Some people have experienced more sweating after the operation than before.
That's right - more sweating. Doesn't sound like a good solution to the problem of excessive sweating, does it? Okay, you have problems with excessive sweating, which can be embarrassing and uncomfortable. You want a solution. That's fair enough. However, ETS Surgery is NOT the solution.

dynamic cerebral autoregulation is altered by ganglion blockade

We measured arterial pressure and cerebral blood flow (CBF) velocity in 12 healthy subjects (aged 29+/-6 years) before and after ganglion blockade with trimethaphan. CBF velocity was measured in the middle cerebral artery using transcranial Doppler. The magnitude of spontaneous changes in mean blood pressure and CBF velocity were quantified by spectral analysis. The transfer function gain, phase, and coherence between these variables were estimated to quantify dynamic cerebral autoregulation. After ganglion blockade, systolic and pulse pressure decreased significantly by 13% and 26%, respectively. CBF velocity decreased by 6% (P <0.05). In the very low frequency range (0.02 to 0.07 Hz), mean blood pressure variability decreased significantly (by 82%), while CBF velocity variability persisted. Thus, transfer function gain increased by 81%. In addition, the phase lead of CBF velocity to arterial pressure diminished. These changes in transfer function gain and phase persisted despite restoration of arterial pressure by infusion of phenylephrine and normalization of mean blood pressure variability by oscillatory lower body negative pressure.
Conclusions-: These data suggest that dynamic cerebral autoregulation is altered by ganglion blockade. We speculate that autonomic neural control of the cerebral circulation is tonically active and likely plays a significant role in the regulation of beat-to-beat CBF in humans.

Horner syndrome, pneumothorax, hemothorax, asymmetry of results, intercostal neuralgia, causalgia, hypoesthesia, incomplete results, paresthesia in the anterolateral abdominal wall, dyspareunia

The complications and side effects are very significant, such as irreversible compensatory sweating (20% to 50%), low satisfaction with results, Claude-Bernard-Horner syndrome, pneumothorax, hemothorax, asymmetry of results, intercostal neuralgia, causalgia, incomplete results, and anesthetic complications11-13.

Retroperitoneoscopic lumbar sympathectomy (video-assisted): this technique is effective in the treatment of isolated or persistent plantar hyperhidrosis (compensatory after thoracic sympathectomy). The treatment consists of removing the nerves of the sympathetic chain located in the abdomen, in the anterolateral portion of the lumbar vertebrae. It requires hospitalization and is carried out under general anesthesia. It may lead to complications such as lesions of structures adjacent to the sympathetic chain, light abdominal distension, neuralgia, and causalgia as well as hypoesthesia in the thighs and groin, limitation of leg movement,
paresthesia in the anterolateral abdominal wall, change in libido, dyspareunia, pulmonary thromboembolism, hemorrhages, arrhythmias, and cardiac decompensation, amongst others. It definitively eliminates plantar hyperhidrosis14,15.

effect of bilateral cervical sympathetic ganglionectomy on the architecture of pial arteries

The influence of the cranial sympathetic nerves on the architecture of pial arteries in normo- and hypertension was examined. For this purpose the effect of bilateral superior cervical ganglionectomy was evaluated in normotensive rats (WKY) and stroke-prone spontaneously hypertensive rats (SHRSP). The operations were performed at the age of 1 wk, which is just prior to the onset of ganglionic transmission. The length of the inner media contour was measured and the media cross-sectional area was determined planimetrically, with computerized digitalization of projected photographic images of transversely sectioned pial arteries. Four wk after sympathectomy there was a 20% reduction in media cross-sectional area and a consequent reduction in the ratio between media area and calculated luminal radius in the major pial arteries at the base of the brain in WKY but not in SHRSP. Conversely, in small pial arteries linear regression analysis showed that in WKY subjected to ganglionectomy the relationship between media cross-sectional area and luminal radius was significantly larger in arteries with a radius less than 21 microns compared to untreated WKY. No such effect was seen in the corresponding SHRSP vessels. In addition, the cross-sectional area of the internal elastic membrane (IEM) in the basilar arteries of WKY was measured by means of a computerized image-analysing system. Mean cross-sectional area of the IEM was approximately 45% larger following SE than in control animals. The present findings propose a 'trophic' role for the sympathetic perivascular nerves in large pial arteries of the rat. The increased media-radius ratio in the small pial arteries of the WKY following sympathectomy might reflect a compensatory hypertrophy due to reduced protection from the larger arteries against the pressure load. The inability to detect any morphometrically measurable effect of the sympathectomy in the cerebral arteries of SHRSP is probably explained by a marked growth-stimulating effect of the high pressure load in these animals.

sympathectomy affects the heart, sweating, and circulation

heart rate was significantly reduced at rest (14%), at sub-maximal exercise (12.3%), and at peak exercise (5.7%), together with a significant increase in oxygen pulse (11.8, 12.7, and 7.8%, respectively). The rate pressure product (RPP) was also significantly reduced following the surgical procedure at all three study stages, while all other physiological variables measured remained unchanged. It is suggested that thoracic-sympathetic denervation affects the heart, sweating, and circulation of the respective denervated region

"ETS has proved moderately successful in treating hyperhidrosis, although the operation does carry a high risk of complications. "

Other complications of ETS include:
  • sweating on the face and neck after eating food (gustatory sweating),
  • inflammation of the nose (rhinitis), and
  • air becoming trapped between the layers of the lung (pneumothorax) which can cause chest pain and breathing difficulties (although this usually resolves itself without the need for treatment).
Rarer complications of ETS include:
  • Horner's syndrome, a condition that causes drooping of the eyelids, and
  • damage to the phrenic nerve (a nerve that is used to help in breathing).
Phrenic nerve damage can lead to shortness of breath, though it may be possible to repair the nerve during surgery.

Permanent side effects included compensatory sweating in 67.4%, gustatory sweating in 50.7% and Horner's trias in 2.5%. However, patient satisfaction declined over time, although only 1.5% recurred. This left only 66.7% satisfied, and a 26.7% partially satisfied. Compensatory and gustatory sweating were the most frequently stated reasons for dissatisfaction. Individuals operated for axillary hyperhidrosis without palmar involvement were significantly less satisfied (33.3% and 46.2%, respectively).

Iatrogenic harlequin syndrome resulting from sympathectomy

Postgrad Med J 2003;79:278 doi:10.1136/pmj.79.931.278
A 29 year old man with severe facial hyperhidrosis underwent an uncomplicated right thoracoscopic sympathectomy. Before operating on his left side, a starch-iodine preparation was applied to his face in order to demarcate residual sudomotor function. The preparation becomes blue on exposure to moisture, thereby representing residual sweat gland activity.
Figure 1 demonstrates that sympathetic innervation to the face is strictly unilateral, and nerve fibres do not appear to cross the midline. This is essentially an iatrogenic variation of the harlequin syndrome,2 which usually results from interruption of post-ganglionic sympathetic fibres secondary to malignant invasion.
His facial hyperhidrosis was completely treated once the contralateral sympathectomy was performed.

T3 sympathectomy leads to subclinical pupillary dysfunction with a tendency for miosis

We found statistically significant differences (P < 0.001) between the preoperative P/I ratio [0.40 mm (standard deviation, SD 0.07 mm)] and the postoperative basal ratio [0.33 (SD 0.05)] at 24 h. The P/I ratio at 24 h increased from 0.33 to 0.36 (SD 0.09), a nonsignificant increase (P = 0.45), after instillation of medicated eye drops. No differences were observed between the preoperative [0.40 (SD 0.07)] and 1-month basal values [0.38 (SD 0.07)], and instillation of apraclonidine no longer induced a hypersensitivity response.

CONCLUSIONS:

T3 sympathectomy leads to subclinical pupillary dysfunction with a tendency for miosis, even though this impairment is not generally evident on standard physical examination or reported by patients. This subclinical dysfunction may be caused by injury to an undefined group of presympathetic nerve cell axons in caudocranial direction that communicate with the cervical sympathetic ganglia and whose function is mydriatic pupillary innervation.

medical students need to realise how vulnerable they are to being seduced by the special privileges of their profession

More than 7% of all German physicians became members of the Nazi SS during World War II, compared with less than 1% of the general population. In so doing, these doctors willingly participated in genocide, something that should have been antithetical to the values of their chosen profession. The participation of physicians in torture and murder both before and after World War II is a disturbing legacy seldom discussed in medical school, and underrecognised in contemporary medicine. Is there something inherent in being a physician that promotes a transition from healer to murderer? With this historical background in mind, the author, a medical student, defines and reflects upon moral vulnerabilities still endemic to contemporary medical culture.
http://jme.bmj.com/content/early/2012/05/02/medethics-2011-100372.abstract

Alessandra Colaianni, of Johns Hopkins Medical School, asks the unsettling question: "Is there something inherent in being a physician that promotes a transition from healer to murderer?" Some recent situations in the United States suggest that this is possible: allegations of euthanasia in the wake of Hurricane Katrina, torture of Guantanamo detainees, and the participation of doctors in capital punishment. Colaianni suggests that there are illuminating parallels between medical training and the work of doctors in Auschwitz.
Socialisation and hierarchy: doctors are pressured to conform to group norms, often with techniques like "Sleep deprivation, heightened stress levels and fear of failure". Ambition: just as Nazi doctors participated in the T4 euthanasia program to advance their careers, today's doctors are pressured to succeed even at the risk of losing their integrity. Doctors have a "licence to sin" which can easily be perverted: some "actions are allowed when they are performed by physicians, but are the stuff of horror films and criminal cases when non-licensed personnel attempt them."
Detachment was also a characteristic of Nazi doctors. They could select prisoners by day and dine with their colleagues by night: "the medical profession requires unflappability in the face of things that others would consider disgusting, horrific, or otherwise overwhelming".
Colaianni concludes that medical students need to realise how vulnerable they are to being seduced by the special privileges of their profession. "It is for this reason that a solid grounding in principles of ethics, individualism and human rights is so crucial for physicians and others in positions of power or trust."
