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].

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.

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.

"return of sweating in the hands is common occurrence in patients followed up for sufficient length of time"

Annals of the Royal College of Surgeons of England (1989) vol. 7.1

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.

Cilio-spinal center can extend to T5

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.

Endoscopic sympathectomy is not minimally 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.

Two-stage unilateral versus one-stage bilateral single-port sympathectomy for palmar and axillary hyperhidrosis

Compensatory sweating occurred in 25 (19%) patients of the one-stage group and in 6 (4%) of the two-stage group (P = 0.0001). No patients developed Horner’s syndrome.
CONCLUSIONS: Both two-stage unilateral and one-stage bilateral single-port video-assisted thoracoscopic sympathectomies are effective, safe and minimally invasive procedures. Two-stage unilateral sympathectomy can be performed with a lower occurrence of compensatory sweating, improving permanently the quality of life in patients with palmar and axillary hyperhidrosis.

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."

Additionally, there have been a few reports of EM patients benefitting from sympathectomy or neurolitic

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. Following sympathectomy the involved extremity shows regional hyper - and hypothermia

"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)"

Seven cases of enlargement of breast following sympathectomy for hyperhidrosis

The  phenomenon  of  hyperhidrosis  is  a  pathological  state  caused  by  unknown  stimulus  of  the  sympathetic  nervous  system.  When  a  variety  of  conservative  treatments have  failed,  surgery  which  involves  the  removal  of  some  ganglia  of  the  cervical  sympathetic  chain,  is  the  treatment  of  choice.  In  the  last  four  years  we  operated  on 253  patients  for  palmar  hyperhidrosis  using  the  transaxillary  approach  only. Recently,  a  new  side  effect  of  surgery  has  come  to  our  attention.  This  phenomenon  is enlargement  of  the  breast  on  the  operated  side.  Our  series  show  seven  cases  (2.4%)  of  women  operated  for  palmar  hyperhidrosis  who  manifested  this phenomenon,  two  of  them  bilaterally.  The  enlargement  of  the  breast  was  found  usually  by  the  second  follow-­up  visit  after  operation  when,  in  most  cases,  the  patient mentioned  it.Examination  of  the  breast  revealed  enlargement  of  a  few  centimeters  which  in  several  patients  required  a  change  to  a  larger  brassiere  size.  In  both  of our  patients  who  underwent  bilateral  surgery,  the  breasts  enlarged  until  they  were  equal  in  size.  The  women  then  did  not  complain  further.

sympathectomy significantly alters vascular responses to warming

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.

Sympathectomy (ETS or ESB) can alleviate social phobia and common fears such as fear of flying, heights, open spaces, or the darkness

Is sympathectomy the new lobotomy?

"ESB may also alleviate social phobia and common fears such as fear of flying, heights, open spaces, or the darkness. In addition, it can be used to decrease trembling of the body, hands, and voice, even stuttering. It may help in alcoholism or drug withdrawal, because these are often linked with social anxiety. 
Sympathetic block is a gentle and exact endoscopic procedure. It is performed as day surgery under light anesthesia."

PURPOSE To compare analgesia traditionally used for thoracic sympathectomy to intrapleural ropivacaine injection in two different doses. METHODS Twenty-four patients were divided into three similar groups, and all of them received intravenous dipyrone. Group A received intravenous tramadol and intrapleural injection of saline solution. Group B received intrapleural injection of 0.33% ropivacaine, and Group C 0.5% ropivacaine. The following aspects were analyzed: inspiratory capacity, respiratory rate and pain. Pain was evaluated in the immediate postoperative period by means of the visual analog scale and over a one-week period. RESULTS In Groups A and B, reduced inspiratory capacity was observed in the postoperative period. In the first postoperative 12 hours, only 12.5% of the patients in Groups B and C showed intense pain as compared to 25% in Group A. In the subsequent week, only one patient in Group A showed mild pain while the remainder reported intense pain. In Group B, half of the patients showed intense pain, and in Group C, only one presented intense pain. CONCLUSION Intrapleural analgesia with ropivacaine resulted in less pain in the late postoperative period with better analgesic outcomes in higher doses, providing a better ventilatory pattern.
