"Similar low values are observed in patients with sympathectomy and in patients with tetraplegia"

Patients with progressive autonomic dysfunction (including diabetes) have little or no increase in plasma noradrenaline and this correlates with their orthostatic intolerance (Bannister, Sever and Gross, 1977). In patients with pure autonomic failure, basal levels of noradrenaline are lower than in normal subjects (Polinsky, 1988). Similar low values are observed in patients with sympathectomy and in patients with tetraplegia. (p.51)



The finger wrinkling response is abolished by upper thoracic sympathectomy. The test is also abnormal in some patients with diabetic autonomic dysfunction, the Guillan-Barre syndrome and other peripheral sympathetic dysfunction in limbs. (p.46)

Other causes of autonomic dysfunction without neurological signs include medications, acute autonomic failure, endocrine disease, surgical sympathectomy . (p.100) 




Anhidrosis is the usual effect of destruction of sympathetic supply to the face. However about 35% of patients with sympathetic devervation of the face, acessory fibres (reaching the face through the trigeminal system) become hyperactive and hyperhidrosis occurs, occasionally causing the interesting phenomenon of alternating hyperhidrosis and Horner's Syndrome (Ottomo and Heimburger, 1980).

"Sympathectomy is a destructive procedure that interrupts the sympathetic nervous system"

Cervico-thoracic or lumbar sympathectomy for neuropathic pain | Cochrane Summaries: "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 by minimally invasive procedures using thermal or laser interruption. Nerve regeneration commonly occurs following both surgical or 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."

Stellate ganglion block alleviates anxiety, depression

Among veterans with post-traumatic stress disorder, treatment with a single stellate ganglion block could help alleviate anxiety, depression and psychological pain rapidly and for long-term use, according to results presented at the American Society for Anesthesiologists Annual Meeting.

• Amygdala activation could predict PTSD susceptibility ...

Researchers performed a single right-sided stellate ganglion block (SGB) using 7 mL of 2% lidocaine and 0.25% bupivacaine under fluoroscopic guidance on 12 veterans with military-related, chronic extreme post-traumatic stress disorder (PTSD) with hyperarousal symptoms. At baseline, 1 week, 1 month, 3 months and 6 months post-block, PTSD symptoms were assessed using the Clinician Administered PTSD Scale (CAPS) score and the Post-traumatic Stress Self Report (PSS-SR) scale. Depressive symptoms were assessed with the Beck Depression Inventory version 2. Anxiety related symptoms with a generalized anxiety scale score and the State-Trait Anxiety Index and psychological pain with the Mee-Bunney scale.

Study results showed the block was greatly effective in 75% of participants, with a positive effects taking effect often within minutes of SGB. At week 1, there was significant reduction of both CAPS and PSS-SR and researchers found CAPS approached normal-to-mild PTSD levels by 1 month. Anxiety, depression and psychological pain scores also were significantly reduced by the block, according to study results. Overall, positive effects remained evident at 3 months, but were generally gone by 6 months.

Permanent pain following sympathectomy

The mean inpatient pain scores were significantly higher in the biportal group (1.2±0.6) than that in the uniportal group (0.8±0.5, P=0.025). For the first three weeks after operation, four out of 20 (20%) patients in the uniportal group constantly suffered from mild or moderate residual pain while eight out of 25 (32%) cases in the biportal group (P=0.366). Among them, two cases in the uniportal group and five cases in the biportal group need to take analgesics.

The so called 'compensatory sweating' is NOT compensatory:

"When patients with intense CH are analyzed, we observe that the amount of released sweat seems to be much greater than was that occurring at the primary hyperhidrosis location, not translating a simple compensation or sweating transference from one site to the other. Therefore, this hyperhidrosis seems to be reflex, mediated neurologically in the sweating regulatory center in the hypothalamus.

In order to avoid this neurologically mediated reflex, the sympathetic afferents to the hypothalamus should be restored, allowing negative feedback to block the efferent projection of the sweating regulatory center on the periphery.(14) Therefore, only the reinnervation of the sectioned sympathetic chain could recover this reflex."

significant adverse effects on cardiopulmonary physiology

Because of technologic advances and improved postoperative recovery, endoscopic surgery has become the technique of choice for many thoracic surgical procedures^6and 25; however, endoscopic visualization of intrathoracic structures requires retraction or collapse of the ipsilateral lung, which can have significant adverse effects on cardiopulmonary physiology. These cardiopulmonary changes can be further affected by the pathophysiologic changes associated with the disease process requiring the surgical procedure.

Because acute changes in cardiopulmonary function can compromise patient safety severely, a clear understanding of the dynamic interaction between the anesthetic–surgical technique and patient physiology is essential. This article discusses the effect of thoracoscopic surgery and the impact of various anesthetic interventions on cardiovascular and pulmonary physiology. In addition, some recommendations for “damage control” are made.

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.

Sympathectomy decreased CD4+ T-cells in lymph nodes - Sympathetic denervation leads to loss of an important regulatory mechanism in immune system physiology

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.

Degeneration patterns of postganglionic fibers following sympathectomy

In the muscle nerves the first signs of an axonal degeneration of the sympathetic fibers can be recognized 4 days after surgery. The signs of axonal degeneration are most striking about 8 days p.o. They have more or less disappeared another week later. The reactions of the Schwann cells also start on the fourth day but outlast the degenerative processes by some 8 days. Thus the degenerative and reactive processes in the reg precede those in the muscle nerves by 2 days early after surgery and by 6 days 3 weeks later. Seven weeks after surgery, fragments of folded basement lamella and Remak bundles with condensed cytoplasm and numerous flat processes are persisting signs of the degeneration.

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).

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."

Because of the anaesthetic implications and possible surgical complications, many surgeons are reluctant to perform transthoracic sympathectomy

Hypoxaemia is of a major concern during thorascopic sympathectomy. However, the pathophysiology of hypoxaemia and consequent decrease in SpO2 differs between the two anaesthetic techniques.

The normal physiological response to massive atelectasis is an increase in pulmonary vascular resistance (hypoxic pulmonary vasoconstriction) with re-routing of blood to well ventilated lung zones and consequent improvement in PaO2. HOWEVER, DURING ENDOBRONCHIAL ANAESTHESIA FOR THORACIC SYMPATHECTOMY THERE IS AN APPARENT FAILURE OF THIS COMPENSATORY MECHANISM. When more then 70% of the lung is atelectatic, compensation by hypoxic pulmonary vasoconstriction appears ineffective.

During carbon dioxide insufflation using endobronchial intubation, Hartrey and colleagues reported a decrease in systolic arterial pressure of >20mm Hg in 21% of patients. Similarly we have reported sudden hypotension and bradycardia after injudicious carbon dioxide insufflation.

Although extremely rare, sudden cardiac arrest has been reported after left T2-3 sympathetic nerve transection. While the exact pathophysiology of this occurence is unclear, it is postulated that before complete transection of the sympathetic trunk, continuous sympathetic stimulation to the stellate ganglions results in a reduction in the ventricular finrillation threshold, arrhythmia and cosequent cardiac arrest.
In an iteresting study of the delayed cardiac effects of T2-$ symtpathectomy, Drott and colleagues demonstrated significantly reduced heart rate at rest, and during both exercise and the recovery phase of exercise. Changes is the electrical axis and shortening of the QT interval have also been reported.

Irrespective of the technique used the reported incidence of postoperative pneumpthorax is variable, occuring in 2-15% of cases.
In a study by Gothberg, Drott and Claes, postoperative chest x-ray after 1274 procedures, in 602 patients demonstrated that a small apical pneumothroax was a usual occurence.

Conclusion: Because of the anaesthetic implications and possible surgical complications, many surgeons are reluctant to perform transthoracic sympathectomy.

after sympathectomy "He becomes more quiet, less impressionable, less agitated, tremor diminishes..."

Everyone seems to agree that when sympathectomy is successful the subjective symptoms of the patient show a considerable improvement. He becomes more quiet, less impressionable, less agitated, tremor diminishes, tachycardia, however, is little influenced or not at all, and the same is true for goiter.
   In conclusion it may be said that the results obtained from sympathectomy when present are very immediate. The ocular symptoms are the ones most happily influenced by the operation; the others such as nervousness, tachycardia, and goiter are problematical.
   Remote Results.- In going over the cases operated by Jaboulay as far back as twelve and fourteen years, A. Charlier was able to find that a number of his patients had been cured completely. He was able to retrace 18 out of the 31 cases operated by Jaboulay from four to fourteen years before. Three of them were completely cured, 9 of them were so ameliorated that the subjective cure was a complete one, the objective cure, however, being incomplete; the 6 remaining cases were doubtful. All these patients experienced considerable benefit to their nervous symptoms; improved and no trophic disturbances of any sort followed as the result of sympathectomy.

Drawbacks of thoracoscopic sympathectomy

Side effects after thoracoscopic sympathectomy have been discussed
widely in Taiwan society in the past few months. Lots of people in Taiwan
suffer from hyperhidrosis palmaris. Thoracoscopic sympathectomy is covered
by our National Health Insurance, and yet patient billing for this
operation does not exceed US$ 60. This is why this operation is so popular
here (1). However, patients with serious compensatory sweating must change
clothes several times a day (some complain they change as often as 10
times a day), resulting in a serious impact on work and social
interaction. Patients suffering from such serious side effects in Taiwan
have formed a support group based on an Internet discussion forum to
request the government to take this problem seriously
(http://home.pchome.com.tw/family/vivi12175/). Since October 2004, The
Department of Health Executive, Yuan, Taiwan, has prohibited surgeons from
performing this operation on patients under 20 years of age. To our
knowledge, this type of Internet-based support group also exists in
England (http://www.noetsuk.com/), Sweden
(http://home.swipnet.se/sympatiska/index3.htm), Australia (http://www.ets-
sideeffects.netfirms.com/), Spain
(http://www.terra.es/personal8/hiperhidrosis/principal.htm) and Japan
(http://www.geocities.jp/etscontroversialop/index.html). Thoracoscopic
sympathectomy is a relatively safe and simple procedure, however, the side
effects are potentially devastating. All surgeons who do the operation and
individuals preparing to undergo this treatment should know this well.

The Effects of Thoracic Sympathotomy on Heart Rate Variability in Patients with Palmar Hyperhidrosis

Compared with preoperative variables, there was a significant increase in the number of adjacent normal R wave to R wave (R- R) intervals that differed by more than 50 ms, as percent of the total number of normal RR intervals (pNN50); root mean square difference, the square root of the mean of the sum of squared differences between adjacent normal RR intervals over the entire 24-hour recording; standard deviation of the average normal RR in- terval for all 5-minute segments of a 24-hour recording (SDANN) after thoracic sympathotomy. Low frequencies (LF, 0.04 to 0.15 Hz) decreased significantly.

Inflammation in dorsal root ganglia after peripheral nerve injury: Effects of the sympathetic innervation

Following a peripheral nerve injury, a sterile inflammation develops in sympathetic and dorsal root ganglia (DRGs) with axons that project in the damaged nerve trunk. Macrophages and T-lymphocytes invade these gan- glia where they are believed to release cytokines that lead to hyperexcitability and ectopic discharge, possibly contributing to neuropathic pain. Here, we examined the role of the sympathetic innervation in the inflammation of L5 DRGs of Wistar rats following transection of the sciatic nerve, comparing the effects of specific surgical in- terventions 10–14 days prior to the nerve lesion with those of chronic administration of adrenoceptor antago- nists. Immunohistochemistry was used to define the invading immune cell populations 7 days after sciatic transection. Removal of sympathetic activity in the hind limb by transecting the preganglionic input to the rele- vant lumbar sympathetic ganglia (ipsi- or bilateral decentralization) or by ipsilateral removal of these ganglia with degeneration of postganglionic axons (denervation), caused less DRG inflammation than occurred after a sham sympathectomy. By contrast, denervation of the lymph node draining the lesion site potentiated T-cell in- flux. Systemic treatment with antagonists of α1-adrenoceptors (prazosin) or β-adrenoceptors (propranolol) led to opposite but unexpected effects on infiltration of DRGs after sciatic transection. Prazosin potentiated the influx of macrophages and CD4+ T-lymphocytes whereas propranolol tended to reduce immune cell invasion. These data are hard to reconcile with many in vitro studies in which catecholamines acting mainly via β2-adrenoceptors have inhibited the activation and proliferation of immune cells following an inflamma- tory challenge.

Endoscopic transthoracic sympathectomy for upper limb hyperhidrosis: Limited sympathectomy does not reduce postoperative compensatory sweating******



In the 84 patients with palmar hyperhidrosis, eight underwent T1-T2 resection, four T1-T3 resection, eight T2-T3 resection, and 64 T2-T4 resection. In the 43 patients with palmar and axillary hyperhidrosis, eight underwent T1-T5 resection and 35 T2-T5 resection. The seven patients with isolated axillary hyperhidrosis underwent T3-T5 sympathectomy. No deaths occurred; one conversion for bleeding, one permanent Horner's syndrome, and six minor complications did occur. The initial cure rate was 99.2%. The initial satisfaction rate was 97%. The mean follow-up period was 44.3 months (range, 7 to 100 months), and complete follow-up was available in 132 patients (98.5%). Ninety-five patients (71.9%) had compensatory sweating develop. Seventy patients (53%) judged their compensatory sweating to be minor and intermittent, and 25 patients (19%) judged it severe (16% embarrassing, 3% disabling). On univariate and multivariate analysis, the extent of denervation was not associated with the occurrence or the severity of compensatory sweating. The late satisfaction rate was 91.5%. Compensatory sweating and temporary relief/recurrence were equally considered to be the main causes of dissatisfaction. Conclusion: Compensatory sweating was the most common long-term complication of thoracodorsal sympathectomy for primary hyperhidrosis. Its incidence and severity were not associated with the extent of sympathectomy. (J Vasc Surg 2003;37:124-8.)"

sympathectomy and parasympathectomy lead to hyperfunction of the serotoninergic system and pathology

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.

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)."

The sympathoadrenal system is one of the major pathways mediating physiological responses in the organism

The sympathoadrenal system is one of the major pathways mediating physiological responsesin the organism. The sympathoadrenal system plays an important role in the regulation of blood pressure, glucose, sodium and other key physiological and metabolic processes. In many disease states, the sympathoadrenal system is affected and by corrective physiological responses the sympathoadrenal system preserves homeostasis. Many therapeutic agents are either adrenergic activators or inhibitors. Therefore, measurements of the components of the sympathoadrenal system and the activity of the sympathoadrenal system have been of major interest for decades.
Levels of plasma (p-) noradrenaline (NA), the sympathetic neurotransmitter, have been used to indicate activity of the neuronal sympathoadrenal component, while adrenaline (Adr) levels indicate activity of the hormonal adrenomedullary component of the sympathoadrenal system (Christensen 1991, Goldstein 1995, Christensen & Norsk 2000).

Based upon the absence of an arterio-venous increase in p-DOPA concentration in sympathectomized limbs and a decrease in p-DOPA after inhibition of tyrosine hydroxylase (TH) in dogs, it was concluded that DOPA can pass across sympathetic neuronal membranes to reach the general circulation and furthermore, that p-DOPA may be related to regional rate of tyrosine hydroxylation (Goldstein et al 1987a). P-DOPA only demonstrated minimal changes during stimuli that produced significant changes in p-NA. Due to partly parallel changes of p-NA and p-DOPA, however, it was believed that p-DOPA reflect the rate of catecholamine synthesis and that p-DOPA was a simple and direct index of TH activity in vivo (Eisenhofer et al 1988, Goldstein & Eisenhofer 1988, Garty et al 1989b). It was inferred that p-DOPA levels may be an index of sympathetic activity.

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."

medical procedures are misrepresented in the media

"If your patients rely on the mainstream media for medical advice, they may well think that cancer has been cured many times over, and have other inflated views about the benefits of new treatments and tests.

AND they probably would be shocked to learn about the potential downsides of many medical interventions, let alone costs.

That’s the conclusion of a comprehensive analysis of almost 2000 medical news items published in the US by print, online and television outlets between 2006 and 2013.

It was undertaken by the media watchdog Health News Review, and recently published in JAMA Internal Medicine (5 May, 2014). Most stories were judged unsatisfactory in how they covered the costs, benefits, harms and quality of the evidence supporting the new treatment or test, and how it was compared to alternatives.

“Drugs, medical devices, and other interventions were usually portrayed positively; potential harms were minimised and costs were ignored,” wrote the founder of Health News Review, Gary Schwitzer."

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.

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. "

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."

Information about surgery for sweaty hands: surgeon "knows the procedure is controversial because of the unpredictability of side-effects"



"Ferrar believes much of the controversy lies in surgeons, mainly in America, who perform the surgery on anyone who asks for it, rather than the severe end of the spectrum.
"In America there are so many that have been operated on when it hasn't been necessary, or the surgeon has given the patient false expectations, that there are support groups for people who've had complications or adverse effects. The people that come to me are almost self-selecting; they've tried everything else."

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.

Peripheral neuropathy gives reduced sensation and sweat ability of the arms and legs but can lead to compensatory sweating of the trunk and head.

Peripheral neuropathy gives reduced sensation and sweat ability of the arms and legs but can lead to compensatory sweating of the trunk and head.

Horner's syndrome due sympatikusskada means, for example Anhidrosis on one half of the face which can then be followed by compensatory hyperhidrosis on the other side. Harlequin syndrome is another name in the same condition in which instead focuses on the color difference where the sympatikusskadade page turns white and the other side is red with exertion. The look can then recall a home to Harelquin.

Sympathectomy was common in the 90s in Sweden. At indications palmar and axillary hyperhidrosis, redness, or social phobia, burned the thoracic sympathetic ganglia endoscopically. Compensatory hyperhidrosis developed below the nipples of a large number of patients 1-6 months after sympatektomin.

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."

"We quickly discovered that lay people often lack the (medical) knowledge to make well-considered judgements"

Jane McCredie: Wishing on risks

Moreover, GPs and plastic surgeons can both be approached directly by patients in The Netherlands. The physicians studied raised many arguments that were expected: they used patient autonomy, risks and benefits, normality and justice to limit wish-fulfilling medicine. In addition, arguments new to this debate were uncovered, which were frequently used to justify compliance with a patient's request. Such arguments seem familiar from conventional medicine, including empathy, the patient–doctor relationship and reassurance. Moreover, certain arguments that play a significant role in the literature on wish-fulfilling medicine and enhancement were not mentioned, such as concepts of disease and the enhancement–treatment dichotomy and ‘suspect norms’.

The sympathetic system is responsible for the physiological responses to emotional states

The common epithet of “fight or flight” is being enlarged to be “fight, flight, or fright” or even “fight, flight, fright, or freeze.” Cannon’s original contribution was a catchy phrase to express some of what the nervous system does in response to a threat, but it is incomplete. The sympathetic system is responsible for the physiological responses to emotional states. The name “sympathetic” can be said to mean that (sym- = “together”; -pathos = “pain,” “suffering,” or “emotion”).

Following a peripheral nerve injury, a sterile inflammation develops in sympathetic and dorsal root ganglia

Following a peripheral nerve injury, a sterile inflammation develops in sympathetic and dorsal root ganglia (DRGs) with axons that project in the damaged nerve trunk. Macrophages and T-lymphocytes invade these ganglia where they are believed to release cytokines that lead to hyperexcitability and ectopic discharge, possibly contributing to neuropathic pain. Here, we examined the role of the sympathetic innervation in the inflammation of L5 DRGs of Wistar rats following transection of the sciatic nerve, comparing the effects of specific surgical interventions 10-14days prior to the nerve lesion with those of chronic administration of adrenoceptor antagonists. Immunohistochemistry was used to define the invading immune cell populations 7days after sciatic transection. Removal of sympathetic activity in the hind limb by transecting the preganglionic input to the relevant lumbar sympathetic ganglia (ipsi- or bilateral decentralization) or by ipsilateral removal of these ganglia with degeneration of postganglionic axons (denervation), caused less DRG inflammation than occurred after a sham sympathectomy. By contrast, denervation of the lymph node draining the lesion site potentiated T-cell influx. Systemic treatment with antagonists of α1-adrenoceptors (prazosin) or β-adrenoceptors (propranolol) led to opposite but unexpected effects on infiltration of DRGs after sciatic transection. Prazosin potentiated the influx of macrophages and CD4+ T-lymphocytes whereas propranolol tended to reduce immune cell invasion. These data are hard to reconcile with many in vitro studies in which catecholamines acting mainly via β2-adrenoceptors have inhibited the activation and proliferation of immune cells following an inflammatory challenge.

Immune cell involvement in dorsal root ganglia and spinal cord after chronic constriction or transection of the rat sciatic nerve.

Hu P, Bembrick AL, Keay KA, McLachlan EM.

Chronic constriction injury (CCI) of the sciatic nerve in rodents produces mechanical and thermal hyperalgesia and is a common model of neuropathic pain. Here we compare the inflammatory responses in L4/5 dorsal root ganglia (DRGs) and spinal segments after CCI with those after transection and ligation at the same site. Expression of ATF3 after one week implied that 75% of sensory and 100% of motor neurones had been axotomized after CCI. Macrophage invasion of DRGs and microglial and astrocytic activation in the spinal cord were qualitatively similar but quantitatively distinct between the lesions. The macrophage and glial reactions around neurone somata in DRGs and ventral horn were slightly greater after transection than CCI while, in the dorsal horn, microglial activation (using markers OX-42(for CD11b) and ED1(for CD68)) was greater after CCI. In DRGs, macrophages positive for OX-42(CD11b), CD4, MHC II and ED1(CD68) more frequently formed perineuronal rings beneath the glial sheath of ATF3+ medium to large neurone somata after CCI. There were more invading MHC II+ macrophages lacking OX-42(CD11b)/CD4/ED1(CD68) after transection. MHC I was expressed in DRGs and in spinal sciatic territories to a similar extent after both lesions. CD8+ T-lymphocytes aggregated to a greater extent both in DRGs and the dorsal horn after CCI, but in the ventral horn after transection. This occurred mainly by migration, additional T-cells being recruited only after CCI. Some of these were probably CD4+. It appears that inflammation of the peripheral nerve trunk after CCI triggers an adaptive immune response not seen after axotomy.
