We studied the balance of activity of sympathetic, parasympathetic, and serotoninergic divisions of the autonomic nervous system in the regulation of the heart function in rabbits. High activities of the sympathetic and parasympathetic system are associated with antagonistic interactions between them. Moderation of activity of these systems could be accompanied by activation of the serotoninergic system. Physiological sympathectomy and parasympathectomy lead to hyperfunction of the serotoninergic system and pathology.

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.

lowering of heart rate and blood pressure, decreased responsiveness of the cardiocirculatory system to emotional stimuli after sympathectomy
"lowering of heart rate and blood pressure, decreased responsiveness of the cardiocirculatory system to emotional stimuli: it is an effect that is especially noticeable in patients operated on for erythrophobia and less evident in those operated for hyperhidrosis. It is almost always a welcome phenomenon, which contributes considerably to the feeling of tranquility and serenity that generally supersedes anxiety. Excessive reduction in blood pressure or heart rate may lead to a state of weakness and fatigue that may require removal of the clips in approx. 2%. This rare state of asthenia contrasts with the increased energy and vigor that most patients experience when they feel freed from overwhelming anxiety."
"The neurovegetative nervous system is, however, very dynamic and tends to adapt continuously during lifetime to all environmental or organic changes and conditions. Therefore, it reacts very individually when a reflex circuit has been blocked. The resulting side effects cannot be predicted in detail, and though they in most patients are relatively mild or even absent, there is a small group of patients developing heavy side effects. Therefore, surgery should only be considered in carefully selected cases in whom non-invasive treatment has failed and in whom the detrimental consequences of erythrophobia regarding the psychosocial situation and the quality of life is such to justify more adverse side effects. It should also always be kept in mind that therapy can be ineffective and that, in the long term, 10-15% of patients do not consider themselves satisfied with the result of surgery. In any case, the author prefers the use of a potentially reversible surgical technique (ESB), instead of destructive techniques (cutting, coagulation, removal of ganglia)."

Abstract
Bone modeling and remodeling are highly regulated processes in the mammalian skeleton. The exact mechanism by which bone can be modeled at a local site with little or no effect at adjacent anatomic sites is unknown. Disruption of the control of modeling within the temporal bone may lead to various bone disease such as otosclerosis, osteogenesis imperfecta, Paget's disease of bone, fibrous dysplasia, or the erosion of bone associated with chronic otitis media. One possible mechanism for such delicate control may be related to the ubiquitous and rich sympathetic innervation of all periosteal surfaces. Previous studies have indicated that regional sympathectomy leads to qualitative alterations in localized bone modeling and remodeling. In this study, unilateral cervical sympathectomy resulted in significant increases in osteoclast surface and osteoclast number within the ipsilateral bulla of experimental animals. The mechanisms by which sympathectomy leads to increased local bone loss is unknown. Potential mechanisms include disinhibition of resorption, secondary to the elimination of periosteal sympathetics, as well as indirect vascular effects."

Chest wall paresthesia affects a significant but previously overlooked proportion of patients following sympathectomy
Paresthetic discomfort distinguishable from wound pain was described by 17 patients (50.0%). The most common descriptions were of ‘bloating’ (41.2%), ‘pins and needles’(35.3%), or ‘numbness’ (23.5%) in the chest wall. The paresthesia resolved in less than two months in 12 patients (70.6%), but was still felt for over 12 months in three patients (17.6%). Post-operative paresthesia and pain did not impact on patient satisfaction with the surgery, whereas compensatoryhyperhidrosis in 24 patients (70.6%) did (P=0.001). The rates and characteristics of the paresthesia following needlescopic VATS are similar to those observed after conventional VATS. Conclusions: Chest wall paresthesia affects a significant but previously overlooked proportion of patients following needlescopic VATS.

very little is known concerning its direct vascular or indirect metabolic effects that will explain its success in some cases and its failure in others
Annals of Internal Medicine | THE HEMODYNAMIC EFFECTS OF SYMPATHECTOMY IN ESSENTIAL HYPERTENSION*: "Surgical sympathectomy has been employed so extensively for the treatment of essential hypertension that one might assume its hemodynamic effects to be completely understood. Quite to the contrary, however, very little is known concerning its direct vascular or indirect metabolic effects that will explain its success in some cases and its failure in others. Until these matters are fully understood the rationale for surgical treatment, and indeed for medical management, of essential hypertension must remain on an empirical basis. For this reason these problems have been and will continue to be the subject of long-term investigation in this laboratory."

The physiology of the sympathetic innervation of the limbs according to the ganglia and their location in correspondence with the ribs is highly variable
The Surgical Treatment of Hyperhidrosis - The Annals of Thoracic Surgery: "The physiology of the sympathetic innervation of the limbs according to the ganglia and their location in correspondence with the ribs is highly variable. Surgery performed by rib count is not anatomical, and rib count is often erroneous: according to Chou and colleagues [3], the estimated rib level was wrong in 5 of 114 patients. "

although producing no alterations in the thermal balance, does produce abnormalities in quantitative distribution of thermoregulatory sweating
JNS - Journal of Neurosurgery -: "The data demonstrate that the surgical removal of both the T-2 and the T-3 ganglia, although producing no alterations in the thermal balance, does produce abnormalities in quantitative distribution of thermoregulatory sweating in man."
the severity of post-sympathectomy (post-SE) dysfunction is unpredictable
"The aim of this study was to identify retrospectively, lumbar sympathectomy (SE) using thermography (TG) and to evaluate clinically, the severity of post-sympathectomy (post-SE) dysfunction after anterior and lateral lumbar interbody fusion procedures (ALIF, XLIF).
METHODS:
Twenty eight patients with suspected SE were referred for TG to both legs. They completed our questionnaire on severity of difficulties after SE. We evaluated the ability of physical examinations to reveal the SE in contrast to TG and compared the symptoms (warmer leg and inhibited leg sweating) of SE with questionnaire responses as subjective measure and TG as objective measure.
RESULTS:
SE was diagnosed in 0.5% after ALIF at L5/S1, in 15% after ALIF at Th12-L5 and in 4% after XLIF at T12-L5. SE severely reduced the quality of life in two cases. The ability to distinguish differences in leg temperature by palpation after SE was found in 32%. All physical examinations together were insufficient for reliably disclosing SE. Subjective symptoms of SE were often false positive and proven SE by TG was often a clinically false negative.
CONCLUSION:
This is the first study to examine post-SE dysfunction objectivelya using TG after ALIF and XLIF, and the first to evaluate clinically, the severity of the post-SE syndrome. Before surgery we cannot foresee potentially poor SE results. For this reason, injury to the sympathetic chain during surgery must be avoided. The advantage of TG for identifying SE is its non-invasiveness and reliability.

most of the existing literature is geared towards assessing only the effectiveness of the surgical sympathectomy
"Given the fact that most of the existing literature is geared towards a) assessing only the effectiveness of the surgical sympathectomy procedures, and b) publishing only studies with positive results, adverse effects and complications are not systematically reported but rather as a secondary outcome. It seems, therefore, highly likely that the complications as reported here, are truly underestimated.
The study indicates that surgical sympathectomy, irrespective of operative approach and indication, may be associated with many and potentially serious complications."

the autonomic nervous system varies in a unique, autonomous manner, and it is therefore difficult to assess changes in patients in a uniform manner
There are several reasons that stellate ganglion block affects the cardiovascular system. Stellate ganglion block will initially affect both the sympathetic and parasympathetic nervous systems based on the degree of block. The intensity of right stellate ganglion blockage of the sympathetic and parasympathetic nervous system will result in heart rate changes and altered activity of the sympathetic and parasympathetic nervous system. Efferent sympathetic innervation from the right stellate ganglion is primarily distributed over the sinus node of the heart, and the influence of the autonomic nervous system and left stellate ganglion block should be assessed. Further, results will be affected by the health status of participants.
Although efferent sympathetic nerves from the stellate ganglion are primarily distributed over the heart, efferent sympathetic fibers from the 2nd to 5th thoracic ganglia affect the heart as well. Accordingly, the autonomic nervous system of the heart is not completely dependent on the stellate ganglia. The influence of the autonomic nervous system cannot be excluded as well. It is worth noting that the mepivacaine in the present study was a lower dosage than those used in other studies. Finally, the autonomic nervous system varies in a unique, autonomous manner, and it is therefore difficult to assess changes in patients in a uniform manner or just through the application of one or two indicators. Future studies should examine diverse methods for the assessment of autonomic nervous system function.

Sympathectomy (ETS) a psychosurgery?
Financial Review - News Store: "It's not unusual to hear people who have undergone sympathectomies describe themselves as feeling emotionally "colder" than before. Among psychologists and neurologists alike there is concern, but no evidence, that the procedure limits alertness and arousal as well as fear, and might affect memory, empathy and mental performance. Professor Ronald Rapee, the director of the Centre of Emotional Health at Sydney's Macquarie University, says he's counselled several people who complain of feeling "robot-like" in the long-term wake of the operation. "They're happy they no longer blush, but they miss the highs and lows they used to feel.""

Dr. Telaranta treating fear, stuttering, stage fright, blushing with sympathectomy. Is ETS a psychosurgery?
Dr. Telaranta | Blog by Dr. Telaranta: "As a treatment, sympathetic blocking could be effective. Fortunately one can test whether it’ll have an effect, to a pretty high level of certainty, by first administering a temporary block t. Sympathetic block is usually effective in reducing all types of fear, why not also in reducing the fear of stuttering.
Sympathetic block typically has the highest likelihood of effective results on both schizophrenia and tremor when fear or anxiety plays a significant part in the onset of symptoms. It is also very effective in treating social phobia, stage fright and blushing. A stage fright-like fear of public presentations is likely common amongst those who stutter."

sympathectomy is based on such anecdotal observation and small case studies which have failed to stand up to scientific scrutiny
Clinical trials do exist and their inability to demonstrate effectiveness suggests an obvious conclusion: the argument for sympathectomy, by chemical or surgical means, is based on such anecdotal observation and small case studies which have failed to stand up to scientific scrutiny. To date there are no reproducible, blinded, randomized studies utilizing control populations which have demonstrated a benefit to sympathetic blockade in CRPS.

Surgical sympathectomy is rarely performed and its use remains controversial
Although improved in some, persistent or recurrent symptoms were present in all patients after six months postoperatively. Increased sensitivity of digital vessels to circulating catecholamines, nerve fiber regeneration or incomplete sympathectomy have been postulated to lead to recurrence. Five patients developed Horner's syndrome postoperatively. A portion of the stellate ganglion was intentionally resected in 3 of the 5 patients.

change in sympathetic nervous system activity after thoracic sympathectomy
The photoplethysmographic (PPG) signal, which measures cardiac-induced changes in tissue blood volume by light transmission measurements, shows spontaneous fluctuations. In this study, PPG was simultaneously measured in the right and left index fingers of 16 patients undergoing thoracic sympathectomy, and, from each PPG pulse, the amplitude of the pulse (AM) and its maximum (BL) were determined. The parameter AM/BL is proportional to the cardiac-induced blood volume increase, which depends on the arterial wall compliance. AM/BL increased after the thoracic sympathectomy treatment (for male patients, from 2.60±1.49% to 4.81±1.21%), as sympathetic denervation decreases arterial tonus in skin. The very low-frequency (VLF) fluctuations of BL or AM showed high correlation (0.90±0.11 and 0.92±0.07, respectively) between the right and left hands before the thoracic sympathectomy, and a significant decrease in the right-left correlation coefficient (to 0.54±0.22 and 0.76±0.20, respectively) after the operation. The standard deviation of the BL or AM VLF fluctuations also reduced after the treatment, indicating sympathetic mediation of the VLF PPG fluctuations. The study also shows that the analysis of the PPG signal and the VLF fluctuations of the PPG parameters enable the assessment of the change in sympathetic nervous system activity after thoracic sympathectomy.

Graph 1 shows the survival rate in both sympathectomised and non sympathectomised rats after the administration of YA cells. The graph shows an overall shorter survival rate of sympathectomised rats. In both groups there is a steep decrease in survival after 15 days, causing the median survival rate (18 days) of both groups to overlap. On the other hand the net survival rate is increased in non sympathectomised rates by 6 days

significant change after sympathectomy: reduced sympathetic and increased vagal tone
The HRV analysis showed a significant change of indices reflecting sympatho-vagal balance indicating significantly reduced sympathetic (LF) and increased vagal (HF, rMSSD) tone. These changes still persisted after 2 years. Global HRV increased over time with significant elevation of SDANN after 2 years. QT dispersion was significantly reduced 1 month after surgery and the dispersion was further diminished 2 years later.

Removal of the clips from the sympathetic trunk does not provide resolution of compensatory sweating
Removal of the clips from the sympathetic trunk does not provide resolution of compensatory sweating in 1 year of observation. T6-9 block does not provide remedy for compensatory hyperhidrosis. Regional abdomino-lumbar iontophoresis seems to be very promising, but further research and followup are mandatory.

Is sympathectomy safe and effective?
Well, it depends on who you ask.
We already know what the surgeons who offer the surgery have to say about it, as most of us was conned into having the surgery. We also know what these surgeons have to say about non-surgical options (ineffective, tedious, time-consuming, expensive, not permanent, resulting in disabling side-effects, very painful, useless - on one website patients are told that application of BOTOX requires general anaesthesia, just to scare them off that one... : http://archive.is/lSWd0 ). The question is answered very differently when you ask a medical professional who offers these non-surgical treatment options. Their advice and their version of FACTS always depends on the treatment and technique they have on offer.
A very simple exercise: print out the texts from few of these websites and offer it to someone to read. Then let them guess what they think which treatment the medical professional is siding with, that is: which treatment is being offered and advertised by them.
Here is a sample. You will most certainly detect that this medical professional is NOT offering ETS, as he selected different FACTS about the procedure and it's results.
and because you can never be safe enough, here is the archived version:

Natural bodily functioning does not include “purely autonomic” or “purely somatic” responses, just as it does not include ‘purely sympathetic” or “purely parasympathetic” responses
Langley initially expected to find afferent cell bodies in autonomic ganglia, with projections to other ganglia. He believed that activation of these “autonomic afferents” should lead to purely autonomic responses. However Langley’s own careful work demonstrated that there were no such neurons.
The fundamentally important point is that integrative processes responsible for the organization of visceral function occur principally within the central nervous system (brain and/or spinal cord). Both somatic and visceral afferents result in complex, brain mediated, responses that include somatic and visceral function. Autonomic motor activity can be generated by both somatic and visceral inputs to the CNS, and visceral inputs to the CNS initiate responses that are both somatic and autonomic. Natural bodily functioning does not include “purely autonomic” or “purely somatic” responses, just as it does not include ‘purely sympathetic” or “purely parasympathetic” responses.

electric stimulation of the sympathetic cord in the upper thoracic level on the middle cerebral artery blood flow velocity
The effect of electric stimulation of the sympathetic cord in the upper thoracic level on the middle cerebral artery blood flow velocity (V(MCA)) in humans was examined using transcranial Doppler sonography monitoring during surgery for palmar hyperhidrosis. Sympathetic stimulation resulted in marked and rapid increases Of V(MCA). The responses were preceded by prompt increases of mean arterial blood pressure (MABP) and heart rate (HR). Division of the sympathetic cord cranially or caudally to the stimulation site partially reduced the V(MCA), MABP and HR responses. Both these operations reduced sympathetic pathways to the heart as reflected by a decrease in HR and MABP. The integrity of the sympathetic pathway from the stimulation site through the superior cervical ganglion and the carotid plexus was not a prerequisite for a V(MCA) response. Our data suggest that the V(MCA) increase mainly results from stimulation of the heart and the cardiovascular system, resulting in marked increases of blood pressure and heart rate.

Postsympathectomy pain of such severity that parenteral narcotics afforded no relief
Fifty-six consecutive patients who subsequently underwent ninety-six lumbar sympathectomies were studied prospectively with regard to the development of postoperative pain. Pain after operation was observed in thirty-four extremities by twenty-five of the patients (35 per cent). It began abruptly an average of twelve days after operation and was often accentuated nocturnally. The pain was almost always described as a deep, dull ache and persisted two to three weeks before spontaneously remitting. Postsympathectomy pain of such severity that parenteral narcotics afforded no relief developed in two of these fifty-six patients and in nine additional patients. Treatment with carbamazepine produced dramatic reduction in the intensity of pain in seven of these nine patients within twenty-four hours after the institution of therapy. Two patients were given intravenous diphenylhydantoin and both experienced immediate relief of pain. The mechanisms of the syndrome and of the action of these drugs are uncertain.

post-sympathectomy hyperalgesia
Behavioral test of tolerance for aversive mechanical stimuli in sympathectomized cats.
Cats were studied behaviorally to determine their suitability as an animal model for the post-sympathectomy hyperalgesia reported to occur in humans. For this study a device and methodology were developed which allow humane testing of tolerance for intense mechanical stimulation of the hindlegs. Behavioral tolerance was measured quantitatively before and after unilateral sympathectomy. The results from this preliminary study of 6 cats are remarkably similar to those reported for humans; 1 of the 6 cats showed a decreased tolerance on the sympathectomized side which was delayed in onset and of limited duration. The new methodology appears to provide relatively stable, quantitative measures of tolerance for aversive stimulation, and the cat shows promise as an animal model for post-sympathectomy hyperalgesia.

significant number of primary hyperhidrosis patients (more than 70%) were so pleased with the results that they decided to forgo the surgery
At the beginning of our study, thoracic sympathectomy was indicated indiscriminately to all primary hyperhidrosis patients. The authors observed a number of patients who were dissatisfied with the results obtained from this technique, particularly due to the undesirable but frequent side effect of compensatory hyperhidrosis. Hyperhidrosis is a condition that deeply affects the individual's emotional component, and many of them, despite being warned previously, are not psychologically prepared to address this new situation. The authors then included a psychologist in the study and directed the patients for routine psychological evaluations to prepare and better select them for surgery. In addition, the authors began to study a pharmacological formula to medicate these patients for the same purpose. Oxybutynin is an anticholinergic drug that has been used safely at high doses (up to 15 mg/day) to treat micturition disorders, and a side effect observed in these patients has been diminished sudoresis. Studies conducted by our group have documented the clinical benefits of a low dose of oxybutynin (10 mg/day). The authors found that a significant number of primary hyperhidrosis patients (more than 70%) were so pleased with the results that they decided to forgo the surgery [50-53].

Neuralgia due to sympathectomy
Depending on the skill of the surgeon and difficulty encountered performing various intraoperative maneuvers, the incidence of complications following sympathectomy should be the same as that following any other extraperitoneal or extrapleural operation. However, a frequent complication following sympathectomy, and one which is apparently unrelated to operative technique, is that of postsympathectomy neuralgia.
This neuralgia is characterized by aching thigh pain after lumbar sympathectomy or aching shoulder and arm pain after cervical sympathectomy. The pain is intense in severity, sudden in onset and disappearance, and not related to any major neurologic manifestations.
Recently we have reviewed the files of the Vascular Surgical Service at the West Roxbury Veteran's Hospital and the literature on this condition. This report is a presentation of our findings.
Incidence Pain following sympathectomy has been described as "an all too common complaint."8 Reports have varied in incidence from 2.1% to "practically every case."

Autonomic neuropathy in the skin following sympathectomy
In diabetics with the anhidrotic syndrome, autonomic nerve fibres were studied in skin biopsies using argentic techniques and light microscopy. The Minor test was used to differentiate normal from anhidrotic skin areas. In the anhidrotic areas, histology of the nerve fibres showed beading, spindle-shaped thickening and fragmentation adjacent to the sweat glands. These changes were similar to those observed in two patients who had previously undergone lumbar sympathectomy. No abnormalities of the sympathetic nerve endings could be found in biopsies taken from normal areas of the forearm of the same patients. We conclude that the diabetic anhidrotic syndrome, a form of diabetic autonomic neuropathy, is due to a lesion of the sympathetic nerve supply to the skin.

ciliospinal reflex
The ciliospinal reflex (pupillary-skin reflex) consists of dilation of the ipsilateral pupil in response to pain applied to the neck, face, and upper trunk. If the right side of the neck is subjected to a painful stimulus, the right pupil dilates (increases in size 1-2mm from baseline). This reflex is absent in Horner's syndrome and lesions involving the cervical sympathetic fibers. The enhanced ciliospinal reflex in asymptomatic patients with cluster headache is due to preganglionic sympathetic mechanisms.

The cilio-spinal center is not sharply confined to TI spinal level, but may extend downwards as low as T5

Endoscopic sympathectomy is not minimally invasive - doing the same operation through a smaller incision is not necessarily less invasive
The term ‘‘minimally invasive surgery’’ was initially applied to coelioscopic procedures such as laparoscopic cholecystectomy and hernia repair, thoracoscopic sympathectomy, and arthroscopy, but has since been abandoned, because doing the same operation through a smaller incision is not necessarily less invasive. The term ‘‘minimally invasive parathyroidectomy’’ does not fully convey the nature of the techniques, and, as previously debated in the wider field of minimal-access surgery, carries connotations of increased safety that are not necessarily supported by the existing data [12].

Endoscopic thoracic sympathectomy remains a fairly controversial procedure
Studies by ETS surgeons have claimed an initial satisfaction rate around 85-95% with at least 2%-19% regretting the surgery and up to 51% of the patients complaining about decreased quality of life. However, at least one study shows a satisfaction rate as low as 28.6.
Most patients report various adverse reactions as a result of the surgery. And, whilst the results of endoscopic thoracic sympathectomy might appear moderately successful in treating hyperhidrosis, there is a high risk of complications.
Along with the normal side effects of surgery, such as pain, bleeding and bruising, the most frequent post surgical complication is ‘compensatory hyperhidrosis’ – where excessive sweating in seen another part of the body as a result, most commonly the lower back or upper thighs.
There is also the potential surgical complication of a pneumothorax, where air becomes trapped between the lung and the internal chest wall, making breathing difficult and painful. Whilst this can be a life-threatening condition, if not too large it generally resolves over time with out further surgical intervention.
Other fairly common complications of endoscopic thoracic sympathectomy include:
Rhinitis - inflammation of the nose and
Gustatory sweating - sweating on the face and neck after eating food,
Rarer complications of endoscopic thoracic sympathectomy as a result of nerve damage include:
Damage to the phrentic nerve. – Phrentic nerve damage can lead to long term shortness of breath, repair of the nerve during the surgery is also possible in some cases..
Horner’s syndrome, - a condition that causes drooping of the eyelids.
Endoscopic thoracic sympathectomy remains a fairly controversial procedure; with advocates claiming high success rates and minimal complications when performed correctly, whilst opponents report huge variation in post operation satisfaction levels and poor consistency in the surgical procedure as a result of anatomical variations in the sympathetic nerve network between patients and personal preferences between doctors.
