Surgical sympathectomy produces most of the retinal changes noted in the retina of an STZ-treated rat in a non-diabetic rat

Sympathectomy significantly increases gene and protein expression of iNOS, as well as levels of PGE2 and protein expression of PGE2-EP2 receptor subtype. Isoproterenol treatment for 6 h to human retinal endothelial cells grown in high glucose medium reduced iNOS protein expression, but had no effect on PGE2 levels or PGE2 receptor protein expression. iNOS expression was attenutated by stimulation with xamoterol, while BRL37344 had no effect, suggesting that the iNOS effects are mediated by beta1-adrenergic receptors. These results suggest that loss of sympathetic activity, as occurs in diabetes, results in an upregulation of iNOS and PGE2-EP2 receptor protein expression, as well as PGE2 levels. Isoproterenol stimulation of human retinal endothelial cells cultured in a hyperglycemic environment decreased iNOS expression with no change in PGE2 levels, suggesting that only iNOS expression is modulated by sympathetic neurotransmission in endothelial cells. Overall, these results further the idea that alterations in sympathetic neurotransmission may result in many of the changes noted in the retina of the STZ-treated rat.

Secondary Effects of Sympathectomy - Disturbance of Sexual Function

If a portion of the autonomic nervous system is removed to modify a specific disease process, unrelated physiologic mechanisms will also be affected. The degree to which these other mechanisms may be affected often governs the selection of operative procedures. The results produced by interfering with mechanisms other than those for which the operation is performed might be designated as side-effects or secondary effects. . . .

We disagree that surgery and botulinum toxin are treatments of choice in severe cases of hyperhidrosis

The truth is exactly the opposite. Surgery is only rarely necessary, and the editorial quite properly warns of numerous surgical pitfalls, which include recurrence of hyperhidrosis, almost certain impotence, compensatory sweating, permanent neurological damage from anoxia, and death (their words). Botulinum toxin, which they recommend for axillary or plantar hyperhidrosis, requires 12 injections per axilla and 24-36 injections per foot. Even this horrendous procedure gives only 11 months' relief, and antibody formation may reduce long term efficiency.

the Kuntz nerve played no part in the success or failure of ETS surgery

If you research the topic of ETS, you will come across various claims and counter-claims
about the importance or otherwise of the Kuntz nerve. The Kuntz nerve is a small nerve
fibre sometimes seen on the second rib not far from the main sympathetic chain. Its
function is not known in humans. Some web-sites on ETS claim success rates of up to
100% for facial blushing because they search for and destroy the Kuntz nerve(s). These
same people also claim to be able to correct failed ETS operations by reoperating and
destroying the Kuntz nerve.
At the meeting of the International Society for Sympathetic Surgery in Germany, May
2003, attended by a majority of the world’s experts in ETS surgery (including us), all but
one of the surgeons present were of the opinion that the Kuntz nerve played no part in the
success or failure of ETS surgery for facial blushing. We share this majority opinion.

Other causes of autonomic dysfunction: sympathectomy

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).

bradycardia and other cardiac complications are common side effects?

The most common side effects of sympathectomy are compensatory sweating, gustatory sweating and cardiac changes including decreasing heart rate, systolic-diastolic and mean arterial pressure. The mechanism of bradycardia and other cardiac complications that develop after thoracic sympathectomy are still unclear.

impairment of autoregulation after unilateral cervical sympathectomy

Although these findings argued against a neurogenic mechanism, James at al. (1969) reported impairment impairment of autoregulation after unilateral cervical sympathectomy in the babbon. Gotoh et al. (1971/1972) observed impairment of autoregulation in patients with the Shy-Drager syndrome.
It was concluded that the autonomic nervous system plays an important role in the mechanism of autoregulation of CBF and that his mechanism is independent of the chemical control of the cerebral vessels. This was confirmed by direct observation of the pial vessels in cats, where separate sites of action in the vascular tree for autoregulation and chemical control were demonstrated; the autoregulatory reaction was located in pial arteries with a diameter larger than 50 μ, and the reaction to carbon dioxide in pial arteries of smaller diameter (Gotoh et al. 1975).
They concluded that the arteries operating in autoregualtin were the larger ones with the dense innervation, while the smaller arteries with sparse innervation were involved in chemical control.
Coronna and Plum (1973) demonstrated the absence of CBF autoregulation in a patient with a Shy-Drager syndrome who had a postganglionic denervation....

Gotoh et al (1979) subsequently showed that autoregulation in patients with this syndrome was impaired irrespective of the localization of the damage to the cervical sympathetic nervous system (preganglionic, central, postganglionic) as judged by the eye instillation test.

Lack of disclosure to ETS patients is unethical and would be criminal in a just society

It is the doctor's moral and ethical duty to provide you with full and honest disclosure of the facts prior to surgery. The whole doctrine of informed consent is to prevent patients from having to realize they made a mistake in hindsight. You shouldn't have had to find out from a former patient's wife that the surgery would cause drenching sweating on your back. It was Garza's job to do that. He completely lied to you regarding the supposed reversibility. Anyone who goes through medical school knows that can't crush a nerve with a metal clamp, remove it later and have the nerve return to normal functioning.

Although it is not possible to predict exactly what will occur in each individual case, there is nearly 100 years of published scientific and medical research available on the effects of sympathectomy. That research paints a very different picture of the effects of this surgery than the one presented to patients considering this surgery. That's the issue. Generally, they lie and tell patients that CS is inconsequential in all but a tiny fraction of cases and simply fail to disclose a huge number of verified adverse effects of the surgery. They take advantage of the patient's ignorance on medical matter. It's unethical and would be criminal in a just society.

In short, you do have a way of knowing what will likely occur as a result of the surgery before you have it done. All the information necessary to make an informed decision exists. It's just not getting to patients.

sympathectomy-induced alterations of immunity

Many studies have demonstrated that ablation of the sympathetic nervous system (SNS) alters subsequent immune responses. Researchers have presumed that the altered immune responses are predominantly the result of the peripheral phenomenon of denervation. We, however, hypothesized that chemical sympathectomy will signal and activate the central nervous

system (CNS). Activation of the CNS was determined by immunocytochemical visualization of Fos protein in brains from male C57BL/6 mice at 8, 24, and 48 h following denervation. A dramatic induction of Fos protein was found in the paraventricular nucleus (PVN) of

the hypothalamus and other specific brain regions at 8 and 24 h compared

to vehicle control mice. Dual-antigen labeling demonstrates that corticotrophin releasing factor (CRF)-containing neurons in the PVN are activated by chemical sympathectomy; however, neurons containing neurotransmitters which may modulate CRF neurons, such as vasopressin,

tyrosine hydroxylase, and adrenocorticotropin, do not coexpress Fos. Our findings suggest an involvement of the CNS in sympathectomy-induced alterations of immunity.

Effects of Sympathectomy on Muscle

We have previously reported functional and histological studies in five beagle dogs with unilateral lumbar sympathectomy. Three months later, fatiguability in the gracilis muscles was increased on the denervated sides, and this was associated with an increase in the relative distribution of FT fibres. Biochemical studies now show that these changes were associated with an increase in cytosolic protein without change in DNA content; this is consistent with
an increase in cell size. There was a reduction in the proportion of slow myosin light chain isoforms from 50 ± 7 to 34 ± 6%. Noradrenaline levels were increased on the denervated sides but this may reflect greater vascularity. Calcium content did not correlate with fibre type but there was a positive relation with both noradrenaline content (r= 0·73;
P<0·05) and DNA content (r= 0·84; P<0·05). It is concluded that sympathectomy induces several biochemical changes in skeletal muscle which constitute a change and increase in fast myosin light chain synthesis and a corresponding fibre type transformation.

The objective of this paper was to study the effect of sympathetic innervation on morphological and histochemical aspects of skeletal muscle tissue. Rabbit masseter muscle was studied using histochemical and immunohistochemical methods for periods of up to 18 months post-sympathectomy. The morphological and enzymatic characteristics of control masseter muscles were similar on both the left and right sides. The main features were muscle fibres with a mosaic pattern and a predominance of type IIa fibres, followed by type I. Type IIb fibres showed very low frequency. Sympathectomized animals showed varying degrees of metabolic and morphological alterations, especially 18 months after sympathectomy. The first five groups showed a higher frequency of type I fibres, whilst the oldest group showed a higher frequency of type IIb fibres. In the oldest group, a significant variation in fibre diameter was observed. Many fibres showed small diameter, atrophy, hypertrophy, splitting, and necrosis. Areas with fibrosis were observed. Thus cervical sympathectomy induced morphological alterations in the masseter muscles. These alterations were, in part, similar to both denervation and myopathy.

paraplegia as a postoperative complication

SIX YEARS AGO we encountered paraplegia as a postoperative complication in a patient who had undergone thoraco-lumbar sympathectomy for hypertension. Such a phenomenon was unique in our experience.
After a search of the literature and a number of informal inquiries among our colleagues, we were surprised to find that such an occurrence is not as unusual as we had believed. Bassett, in 1948,1 reporting on his experience with sympathectomy in the treatment of hypertension, stated: 'We
have had four cases of thrombosis of the anterior spinal artery with resultant permanent residual ischemic myelitis.
Poppen, in a personal communication, has stated that, although this complication has not
occurred in his own experienoe, three cases have been brought to his attention in which
paraplegia followed thoraco-lumbar sympathectomy for hypertension. Therefore, we have knowledge of eight cases in which such a catastrophe followed an elective operation which has enjoyed wide usageduring the past decade.

Spinal Cord Infarction caused by sympathectomy

Uncommon causes include decompression sickness, which has a predilection for spinal ischemic damage; complications of abdominal surgery, particularly sympathectomy; circulatory failure as a result of cardiac arrest or prolonged hypotension; and vascular steal in the presence of an arteriovenous malformation.

cerebral edema is worsened by sympathectomy, which causes increased cerebral blood flow

Although excessive SNS activity may be globally harmful, catecholamines and sympathetic nerves may also have organ-protective effects via reflex arteriolar constriction, which may protect the capillaries of the brain and kidney from surges in SBP. A baroprotective role of cerebral sympathetic nerves was uncovered by Heistad et al., who unilaterally denervated the cerebral vasculature in stroke-prone rats and found that fatal stroke occurred rapidly in the hemisphere ipsilateral to the sympathetic denervation. In the syndrome of malignant hypertension, cerebral edema is worsened by sympathectomy, which causes increased cerebral blood flow.

depletion of brain noradrenaline levels causes a disturbance in cerebral microvascular tone

A hypertensive condition at a mean arterial pressure of about 160 mm Hg was maintained for 1 hour by intravenous infusion of phenylephrine. In the 6-hydroxydopamine-treated group, CBF increased significantly after the elevation of systemic blood pressure compared with that in the control group, and cerebral autoregulation was impaired. After a 1-hour study, the specific gravity of the cerebral tissue in the treated group significantly decreased; electron microscopic studies at that time revealed brain edema.
It is suggested that depletion of brain noradrenaline levels causes a disturbance in cerebral microvascular tone and renders the cerebral blood vessels more vulnerable to hypertension.

Unilateral removal of the superior cervical ganglion (SCG) results in the reinnervation of the denervated cerebral vessels by sprouting nerves

Chemical sympathectomy of the mature rat rather than the neonate also leads to sensory hyperinnervation, although there are a few differences. In the lung, sympahtectomy induces a marked increase in CGRP-immunoreactive nerve density around the ariways, blood vessels, and also in the vicinity of the neuroepithelial bodies of the pulmonary epithelium.

Following transection of the preganglionic autonomic nerves or in spinal cord injury, there are marked changes in the nerves that remain. Such changes can be manifested not only as nerve growth and changes in neurotransmitter expression, but remarkably, in reorganization of nerve pathways and their function.

Since sprouting is a common response of the nerves that remain following nerve injury, the close association of the different divisions of the autonomic nervous system in the pelvic region opens up the possibility for new connections to form new pathways. Spinal cord injury can unmask spinal reflexes that are normally inhibited by input from higher centers in the brain.

adverse cardiac and cerebral intraoperative events secondary to hypoxia from presumed hypoventilation

The thoracoscopic sympathectomy procedure requires several anesthetic considerations that include an anesthesiologist and operating room staff familiar with thoracic endoscopy. Double-lumen endotracheal tube placement is needed for ventilation of the contralateral lung and active deflation of the ipsilateral lung. Care must be taken to ensure adequate inflation of the lung on the operated side before proceeding to the contralateral side because there have been both published and anecdotal reports of adverse cardiac and cerebral intraoperative events secondary to hypoxia from presumed hypoventilation.
The choice whether to use carbon dioxide insufflation versus ambient pressure coupled with lung deflation and a fan refractor is surgeon specific. There are case reports of intraoperative cardiac arrest requiring resuscitation when carbon dioxide insufflation was used, with speculation that an increased mediastinal or intrathoracic pressure resulted in a decreased stroke volume and subsequent arrhytmia.

alterations in the three-phase bone scan in acute CRPS are similar to those resulting from sympathectomy

There is only limited evidence regarding the efficacy of thoracoscopic or surgical sympathectomy. Four studies reported partial long-lasting benefits in CRPS types 1 and 2.

Postoperatively, no vasoconstriction due to deep inspiration (vasoconstrictor reflex) could be elicited at the affected extremity, indicatin complete sympathetic denervation. Additionally the temperature at the affected hand increased. After 4 weeks, skin temperature decreased, without signs of reinnervation. This denervation supersensitivity was associated with recurrence of pain and is thought to rely on a vascular supersensitivity to could and circulating catecholamines.

Interestingly, alterations in the three-phase bone scan in acute CRPS are similar to those resulting from sympathectomy without being related to the success of the intervention. (p.370)

cerebral edema following CO2 insufflation

Death after thoracoscopic sympathectomy has been reported, secondary to cerebral edema, when CO2 insufflation has been employed. Another patient in this series sustained severe neurological dysfunction, secondary to cerebral edema. The development of cerebral edema after thoracoscopic sympathectomy is attributable to gas insufflation, which is not required and should be avoided. Major vascular injury during thoracoscopic sympathectomy has also been reported, and this complication should be completely avoidable. Chylothorax after sympathectomy has also been described and is related to division of accessory ducts rather than injury to the thoracic duct.
The most common complications of sympathectomy are related to manipulation of the autonomic nervous system.

Injury to the stellate ganglion is caused by mechanical or thermal damage to T1 during dissection. In order to prevent this injury, precise identification of ribs 1-4 is required prior to dissection of the sympathetic ganglion at T2; no dissection is performed above this level. Furthermore, excessive nerve traction is avoided during dissection. Finally, the use of bipolar cautery or ultrasonic dissection will prevent current diffusion to the stellate ganglion.
Neuralgia along the ulnar aspect of the upper limb may occur after sympathectomy, which usually resolves within 6 weeks. (p.250)

Sympathectomy. This is a radical, now-controversial approach to blocking pain, and it includes extremely high risks for additional tissue damage and spread of RSD. (p.40)

Sympathectomy also potentially precludes future new treatments from working. (p.41)

A recent review article by (Johns Hopkins Hospital anesthesiologist and medical school professor) Srinivasa Raja covering all previous articles on sympathectomy showed that 10 percent of sympathectomies done for various reasons have complications. The complication rate for sympathectomy done to treat neuropathic (i.e., RSD) pain is 30 percent. A lot of these people can have a return of pain, and if they do, you can no longer do a sympathetic block to get rid of it. Then you have got these people in terrible pain that you cannot treat. And so, in my book, surgical sympathectomy is out. (p.81)

Post-Sympathectomy pain (neuralgia)

Post-Sympathectomy pain (neuralgia) is a potential complication of all types of sympathectomy. Post-Sympathectomy pain is typically proximal to the original pain (e.g. proximal means that the pain may appear for the first time in the groin or buttock region for sympathectomy of the lower extremity and pain in the chest wall region for sympathectomy of the upper extremity).

Sympathectomy at the T2 level would block the afferent projection negative feedback to the hypothalamus

Sympathectomy at the T2 level would block the afferent projection negative feedback to the hypothalamus, since it would section practically all afferent pathways, and would favor CH appearance at the periphery, due to the continuous efferent projections from the hypothalamus. Sympathectomy below this level would section a smaller number of afferent pathways, avoiding the feedback blockage and decreasing CH.

By understanding that CH is a result of a lack of negative feedback to the hypothalamus after sympathectomy, we found out that this side effect is more pronounced when sympathectomy is performed on the T2 ganglion, where there is greater convergence of afferent pathways to the hypothalamus. However, when the sympathectomy is more caudal, the adverse effect is less pronounced.

Endoscopic sympathetic block as a treatment for primary hyperhidrosis is associated with certain sequelae. The reported occurrence of side effects still varies in the literature. As the majority of patients describe sequelae after sympathetic surgery, the frequency and importance of these persisting changes are still underestimated. Patient's informed consent should include and define side effects like gustatory sweating, olfactory sweating and bradycardia as likely, and compensatory sweating as obligatory.

Overall, gustatory sweating occurred in 32% of patients

Gustatory sweating is a frequent side effect after thoracoscopic sympathectomy. This is the first study to report that its incidence is significantly related to the extent of sympathectomy or the location of primary hyperhidrosis. Although there is no pathophysiologic explanation of gustatory sweating, these findings should be considered before planning thoracoscopic sympathectomy and patients should be thoroughly informed.

Side-effects of Sympathectomy treated with further surgical procedure and botox

Compensatory hyperhidrosis: a consequence of truncal sympathectomy treated by video assisted application of botulinum toxin and reoperation.

Surgical management of primary hyperhidrosis by upper dorsal sympathectomy is the treatment of choice for intractable hyperhidrosis, however, paradoxically it may be followed by troublesome compensatory hyperhidrosis in a significant number of patients.

We report for the first time the successful treatment of a patient who developed compensatory hyperhidrosis following sympathectomy using video assisted extension of the sympathectomy by application of botulinum toxin (BTX-A).

Sympathicotomy affects cutaneous blood flow, temperature, and sympathicus-mediated reflexes

To study the sympathetically mediated effects of transthoracic endoscopic sympathicotomy (TES) in the treatment of severe primary palmar hyperhidrosis. MATERIALS AND METHODS: The effects of TES, on sympathetic ganglia at the thoracic level of 2-3, finger blood flow, temperature, and on heat and cold provocation were investigated. Middle cerebral artery (MCA) blood flow velocities were studied by transcranial Doppler. RESULTS: The finger blood flow increased by about 700% after TES and finger temperature by 7.0 +/- 0.5 degrees C. Several autonomic reflexes were dramatically affected. A finger pulp-shrinking test showed a major decrease after surgery. MCA mean blood flow velocities were not affected by TES. CONCLUSIONS: Besides the high success rate of good clinical effect of TES on palmar hyperhidrosis, major effects on local blood flow and temperature are elicited by TES. Complex autonomic reflexes are also affected. The patient should be completely informed before surgery of the side effects elicited by TES.
