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 youngest patient he has performed an endoscopic thoracic sympathectomy on was 8 years old, with most being in puberty (when the condition tends to arise). Or they are in their 20s when they are beginning relationships and jobs."

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

Google Translate:

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.

Freys'syndrom arise after salivary gland surgery faulty growing parasympathetic salivary fibers innervate the sweat glands in the cheek. This means that when the patient eats or even just thinking about food so producing a profuse perspiration from his cheek

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.

This is the first study to examine post-SE (post-sympathectomy) dysfunction objectively

This is the first study to examine post-SE dysfunction objectively 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.

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).

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, by chemical or surgical means, 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.

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.

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.

The graph shows an overall shorter survival rate of sympathectomised rats

Chemical sympathectomy was performed by double intraperitoneal administration of 6-hydroxydopamine (6OHDA) 100mg/1 kg. 6OHDA is a neurotoxin used for selective ablation of dopaminergic and noradrenergic neurons. YA cells AH-130 which typically grow as free cells in ascites were injected intraperitoneally in amount of 20 - 25 mil/2 ml.

               

                Four groups of Wistar rats (AnLab, Prague) weighing 150 - 175g were used in the experiment. An absolute control group (8 rats), and a control sympathectomised group (8 rats), a group injected with YA cells (16 rats) and the last group was sympathectomised and injected with YA cells (16 rats).

               

                After a week of acclimatization of rats to conditions of animal room, sympathectomy was performed. One week later, YA cells were applied. The incidence and growth of ascites, and mortality were monitored.

Results

                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.

Decreased HRV is predictive of adverse cardiovascular outcomes in a variety of disease states

Water immersion-induced skin wrinkling (WISW) is dependent on intact peripheral sympathetic function. WISW was hypothesized to reflect autonomic function in subjects with- out peripheral neuropathy. We prospectively studied 70 healthy subjects (aged 31 88 years, 63% females) without cardiovascular risk factors or neurological disease. All sub- jects underwent short-term heart rate variability (HRV) stud- ies. Time and frequency domain variables were derived in- cluding the HRV index. WISW was graded using a previously validated scale of 1–4 of which 18.6% of subjects exhibited grade 1 (minimal) WISW and 35.7% had grade 2 WISW. On multivariate analysis using the HRV index, WISW was inde- pendently related to height and the HRV index. We conclude that WISW is related to central autonomic function.

Although the mechanism is not fully understood, WISW is felt to be caused by passive diffusion of water across the stratum corneum into the sweat ducts, which in turn alters electrolyte balance, decreases membrane stabilization, increases sympathetic neural firing and stimulates vasoconstriction [1–3, 8].WISW is decreased in diabetic patients and in patients after cervical sympathectomy [4, 9].

Heart rate variability (HRV) is the beat-to-beat variation in cardiac cycle length due to autonomic influence on the sinus node. Decreased HRV is predictive of adverse cardiovascular outcomes in a variety of disease states[5]. The influence of the central nervous system activity on autonomic function suggests that HRV may be a useful prognostic indicator in patients with cerebrovascular events [6].

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.

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.

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.

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.

progressive hemifacial atrophy following sympathectomy for hyperhidrosis

Some authors consider the disease a variant of mor- phea because the histologic changes are identical to deep scleroderma.2 The possible etiologies include sympathetic denervation, trauma, vascular malformations, immunologic abnormality, heredi- tary disease, or infection by a slow virus.3 To our knowledge, this is the first report of a young patient with a possible association between Parry-Romberg syndrome and thoracoscopic sympathectomy.

Theoretically, thoracoscopic sympathectomy may cause 2 of the aforementioned etiologies of Parry- Romberg syndrome: sympathetic denervation and trauma. Thoracoscopic sympathectomy is a surgical technique for the treatment of palmar hyperhidrosis.

The operation ablates the upper thoracic sympa- thetic nerve ganglions responsible for nerve stimu- lation of the sweat glands of the upper limbs. The most significant complication is Horner’s syn- drome, which results from injury to the stellate sympathetic ganglion.7 In a summary of sympa- thectomies in 67 children and adolescents, compli- cations included Horner’s syndrome in 1 patient (1%) and varying degrees of compensatory sweat- ing in 30 patients (45%).8 Despite the evidence from animal studies that sympathectomy can result in facial atrophy, to our knowledge, there were no previous reports of such an association in humans.

RSD due to nerve injury

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 (redness, warmth, swelling). RSD is not thought to have a single cause, but rather multiple causes producing similar symptoms.

PLOS Medicine: Why Most Published Research Findings Are False

PLOS Medicine: Why Most Published Research Findings Are False: "There is increasing concern that most current published research findings are false. The probability that a research claim is true may depend on study power and bias, the number of other studies on the same question, and, importantly, the ratio of true to no relationships among the relationships probed in each scientific field. In this framework, a research finding is less likely to be true when the studies conducted in a field are smaller; when effect sizes are smaller; when there is a greater number and lesser preselection of tested relationships; where there is greater flexibility in designs, definitions, outcomes, and analytical modes; when there is greater financial and other interest and prejudice; and when more teams are involved in a scientific field in chase of statistical significance. Simulations show that for most study designs and settings, it is more likely for a research claim to be false than true. Moreover, for many current scientific fields, claimed research findings may often be simply accurate measures of the prevailing bias. In this essay, I discuss the implications of these problems for the conduct and interpretation of research."

sympathectomy led to significant decrements in escape and avoidance responding

PsycNET - Option to Buy: "Chemical sympathectomy and avoidance learning in the rat.

Journal of Comparative and Physiological Psychology, Vol 81(3), Dec 1972, 491-500.
Abstract
Reports results of 5 experiments with male Wistar rats (N = 108). Depletion of peripheral sympathetic noradrenaline induced by administration of 6-hydroxydopamine, ip, led to significant decrements in escape and avoidance responding when the required response was difficult, but not when it was relatively easy to acquire. Results are similar to previous findings obtained with adrenal-demedullated Ss. Findings clarify the role of the sympathetic nervous system in the motivation of behavior elicited by aversive stimulation. Implications for 2-process theory and the "Kamin effect," or "learned helplessness," are discussed. (40 ref.) (PsycINFO Database Record (c) 2012 APA, all rights reserved)"

Blushing and Facial Blushing Causes, Treatment, Diagnosis

Blushing and Facial Blushing Causes, Treatment, Diagnosis: "The treatment of facial blushing and or facial sweating is a controversial subject. The uncontrolled and embarrassing situation of facial sweating and blushing was thought to be easily treated with ETS. This came about when ETS was done patients with sweaty hands. Among those patients who also suffered from facial blushing and/or facial sweating the results were also successful at reducing facial blushing and/or sweating. However over the years two observations were made when this operation was applied only patients with facial blushing and or facial sweating. Percentage wise these patients developed a higher rate of severe compensatory sweating. Also these patients experienced a higher degree of dissatisfaction due to the side effects. Side effects such as facial flushed feelings, loss of stamina, facial skin sensitivity, increased amount of fatigue and others led Dr. Reisfeld to the decision not to perm ETS when only facial blushing or facial sweating were involved. The clinical experience that was accumulated over the last several years is what has allowed Dr. Reisfeld to reach this assessment."

Severity of compensatory sweating after thor... [Ann Thorac Surg. 2004] - PubMed - NCBI

Severity of compensatory sweating after thor... [Ann Thorac Surg. 2004] - PubMed - NCBI: "Compensatory sweating occurred in 89% of patients and was so severe in 35% that they often had to change their clothes during the day. The frequency of compensatory sweating was not significantly different among the three groups, but severity was significantly higher after Th2-4 sympathectomy for axillary hyperhidrosis (p = 0.04). Gustatory sweating occurred in 38% of patients, and 16% of patients regretted the operation.
CONCLUSIONS:
Compensatory and gustatory sweating were remarkably frequent side effects after thoracoscopic sympathectomy for primary hyperhidrosis."

Impaired skin vasomotor reflexes have been found in patients with sympathetic dystrophies, dysautomias, post-regional sympathectomy and diabetic neuropathies

Not surprisingly, diminished vasoconstrictor responses, similar to the current findings, have been found
in patients with sympathetic dystrophies [26], dysautomias [27], post-regional sympathectomy [28] and
diabetic neuropathies [11].


Additionally, there have been a few reports of EM patients benefitting from sympathectomy or neurolitic
irreversible blocks of the lumbar sympathetic ganglia [22,23], while others have found the symptoms of EM to be aggravated by such treatment [24,25], possibly as a result of denervation supersensitivity.

Sympathectomy interrupts neural messages that ordinarily would travel to many different organs, glands and muscles

Sympathectomy involves dissection of the main sympathetic trunk in the upper thoracic region thus interrupting neural messages that ordinarily would travel to many different organs, glands and muscles. It involves division of adrenergic, cholinergic and sensory fibers which elaborate adrenergic substances during the process of regulating visceral function.
Journal of Applied Sciences Research, 6(6): 659-664, 2010

Vascular sympathetic denervation can lead to degeneration of the smooth muscle of arteries leading to medial arterial calcification and stiffening of the arteries.

Sympathetic denervation of the peripheral arterial system may occur quite early in the evolution of neuropathy and has major effects on blood flow and vascular responses and causes structural changes in the arterial wall (Edmonds 2004). Vascular sympathetic denervation can lead to degeneration of the smooth muscle of arteries leading to medial arterial calcification and stiffening of the arteries. This calcification may assume the histological characteristics of bone.

   Unilateral lumbar sympathectomy in humans, both in diabetics and non-diabetics, has been show to result in medial wall calcification on the ipsilateral side (Goebel and Fuessl 1983). Unilateral sympathectomy in animals leads to excess deposition of cholesterol on the operated side and the occurrence of cholesterol sclerosis in the rabbit's aorta was accelerated by removal of the coeliac ganglion (Harrison 1938). Furthermore, in animal models, denervation of smooth muscle leads to striking pathological changes, including atrophy of muscle fibres with foci of degeneration (Kerper and Collier 1926). Arterial calcification in initiated within senescent atrophic smooth muscle (Morgan 1980).

   Medial arterial calcification in the Pima Indians is significantly associated with an increased prevalence of cardiovascular mortality (Everhart et al 1988). Medial calcification may be important factor in development of peripheral vascular disease, which in diabetes shows a predilection for the distal arteries below the knee and is unexplained. Chantelau reported an association of below knee atherosclerosis to medial arterial calcification (Chantelau et al. 1995).

Sympathectomy, (ETS, VATS, ESB and many other names for the same procedure) affects emotional responses, fear responses, arousal, etc. It changes a person's  ability to feel and respond to emotions. It changes drive, attention, mobilisation.
Patients sign up for a surgery to treat sweaty hands, and not 'adjustments' to their emotions and personality.

sympathectomy leads to fluctuation of vasoconstriction alternated with vasodilation in an unstable fashion

"To quote Nashold, referring to sympathectomy, "Ill- advised surgery may tend to magnify the entire symptom complex"(38). Sympathectomy is aimed at achieving vasodilation. The neurovascular instability (vacillation and instability of vasoconstrictive function), leads to fluctuation of vasoconstriction alternated with vasodilation in an unstable fashion (39). Following sympathectomy the involved extremity shows regional hyper - and hypothermia in contrast, the blood flow and skin temperature on the non- sympathectomized side are significantly lower after exposure to a cold environment (39). This phenomenon may explain the reason for spread of CRPS. In the first four weeks after sympathectomy, the Laser Doppler flow study shows an increased of blood flow and hyperthermia in the extremity (40). Then, after four weeks, the skin temperature and vascular perfusion slowly decrease and a high amplitude vasomotor constriction develops reversing any beneficial effect of surgery (39). According to Bonica , "about a dozen patients with reflex sympathetic dystrophy (RSD) in whom I have carried out preoperative diagnostic sympathetic block with complete pain relief, sympathectomy produced either partial or no relief (40)"

Sympathectomy significantly alters vascular responses

Vascular responses to warming were studied in hemiplegic patients and after sympathectomy, using venous occlusion plethysmography of foot and leg. Comparisons were made with corresponding age groups. The pattern of response was essentially unchanged in hemiplegic patients, but was altered substantially where sympathetic pathways had been interrupted.
