Surgical Denervation of Ocular Sympathetic Afferents Decreases Local Transforming Growth Factor-β and Abolishes Immune Privilege

Mounting evidence points to a role for the sympathetic nervous system in suppressing inflammation. This role might be of specific relevance for immune privilege in the eye, where, sporadically, patients with denervated sympathetic fibers develop chronic inflammation.

Our results show that in the absence of functional sympathetic fibers, the eye loses its ability to prevent either the immune rejection of intraocular allogeneic tumor cells or the suppression of delayed type hypersensitivity responses against soluble antigens injected in the anterior chamber. This loss of immune privilege is accompanied by a decrease in the concentration of transforming growth factor-β in the aqueous humor. These results suggest that immune privilege is lost in the absence of a functional sympathetic innervation of the eye, allowing intraocular immune responses to become exaggerated. We conclude that ocular sympathetic nerves are critical for the generation and maintenance of immune privilege in the eye through the facilitation of local transforming growth factor-β production.

Cervical sympathectomy causes photoreceptor-specific cell death in the rat retina

Changes in the regulation of the vasculature of the eye may be related to some age-related ocular diseases. We have previously shown that loss of sympathetic innervation, as can normally occur with age, resulted in substantial vascular growth of the choroid. The current study was designed to determine whether changes induced by sympathetic denervation causes significant loss of photoreceptors and increased glial cell reactivity in the retina. Sympathetic denervation was performed followed by immunohistochemistry, TUNEL staining, and protein expression analysis to investigate photoreceptor loss. There was a significant reduction (30%) in photoreceptor numbers in the sympathectomized eye. This loss was due to apoptosis, as there was over a doubling in apoptotic cell numbers after sympathectomy. This loss of photoreceptors in the sympathectomized eye resulted in a significantly reduced width of the outer nuclear layer of the retina when compared to the contralateral eye. Increased glial fibrillary acidic protein (GFAP) staining was also noted after sympathectomy in the ganglion cell layer with streaking toward the bipolar cell layer. These results suggest that loss of sympathetic innervation may cause significant changes to the physiology of the choroid.

morphological changes in the retina noted after sympathectomy

Results: Mice treated with PDGF inhibitor AG 1296 showed an inhibition of corneal neovascularization and a reduction of pericytes in the new formed vessels compared to untreated animals. 

Retina from sympathectomized eyes receiving saline treatment had significantly  reduced PEDF mRNA and protein expression relative to the contralateral eye receiving saline treatment. These results are similar to previous work and indicate that injection alone did not alter the results. Intravitreal PEDF administration to sympathectomized eyes returned both mRNA and protein levels to those of the contralateral eye. PEDF administration also normalized retinal morphometry to prevent the sympathectomy-induced increases 

in capillary density of the outer plexiform layers, as well as the ganglion cell layer. 

Conclusions: These results suggest that one injection of PEDF can restore protein and mRNA 

levels to those noted in an untreated animal. Furthermore, these results also indicate that 

one injection of PEDF can reverse the morphological changes noted after sympathectomy 

in the retina.

acute mesenteric ischemia and massive intestinal infarction secondary to bilateral lumbar sympathectomy

A case of acute mesenteric ischemia and massive intestinal infarction secondary to bilateral lumbarsympathectomy and without any other apparent precipitating factors is presented. Its characteristics and findings significantly agree with those described as part of the mesenteric arterial steal syndrome. Although this syndrome was originally described as secondary to surgical revascularization of the lower extremities, experimental studies have shown that lumbar sympathectomy, by means of reducing the peripheral vascular resistance in the lower extremities, similarly causes intense hemodynamic alteration of the mesenteric circulation due to the sudeen redistribution of blood flow to the lower limbs at the expense of the mesenteric flow. When marginally compensated occlusive mesenteric arterial disease exists prior to surgery, the sudden fall in the arterial pressure gradients in this vessel can precipitate the occlusion of these arteries, resulting in mesenteric ischemia and intestinal infarction. It has also been suggested that an intense vasospamodic neurogenic reflex in the mesenteric arteries is an important factor in the pathogenesis of this syndrome.

sympathectomy led to an exacerbation of colitis

Substance P (SP) is a pro-inflammatory neuropeptide in colitis, whereas sympathetic neurotransmitters are anti-inflammatory at high concentrations.

Results: In all layers, Crohn’s disease patients demonstrated a loss of sympathetic nerve fibres. Sprouting of SP⁺ nerve fibres was particularly observed in the mucosa and muscular layer in Crohn’s disease. SEMA3C was detected in epithelial cells, and there was a marked increase of SEMA3C-positive crypts in the mucosa of Crohn’s disease patients compared to controls. In Crohn’s disease, the number of SEMA3C-positive crypts was negatively related to the density of mucosal sympathetic nerve fibres. Sympathectomy reduced acute DSS colitis but increased chronic DSS colitis. Sympathectomy also increased chronic colitis in Il10^−/−mice.

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. . . .

after unilateral sympathectomy found that his previous and customary sensation of shivering while listening to a stirring passage of music occurred in only one side

Sweet* has reported the case of a very intelligent patient, the dean of a graduate school, who after a unilateral sympathectomy to treat his upper limb hyperhidrosis, found that his previous and customary sensation of shivering while listening to a stirring passage of music occurred in only one side and he could not be thrilled in the sympathectomized half of his body. These cases were interesting because emotions are usually experienced in a rather diffuse and bilateral fashion unless innervation has been specifically interrupted. (p.134.)

Autonomic determinism: the modes of autonomic control, the doctrine of autonomic space, and the laws of autonomic constraint

Contemporary findings reveal that the multiple modes of autonomic control do not lie along a single continuum extending from parasympathetic to sympathetic dominance but rather distribute within a 2-dimensional space. The physiological origins and empirical documentation for the multiple modes of autonomic control are considered. Then a formal 2-dimensional conception of autonomic space is proposed, and a quantitative model for its translation into a functional output surface is derived. It is shown that this model (a) accounts for much of the error variance that has traditionally plagued psychophysiological studies, (b) subsumes psychophysiological principles such as the law of initial values, (c) gives rise to formal laws of autonomic constraint, and (d) has fundamental implications for the direction and interpretation of a wide array of psychophysiological studies.

sympathectomy may result in the loss of a trophic influence which is important in the regulation of osteogenesis

Grain counts over periosteal osteoblasts of the femoral diaphysis and osteoblasts mesial to the first molar in the mandible demonstrated a significantly reduced uptake of ³H-proline in the sympathectomized rats. The data provide direct evidence of sympathetic influence on osteoblastic activity and suggest that sympathectomy may result in the loss of a trophic influence which is important in the regulation of osteogenesis.

Progressive facial hemiatrophy following cervical sympathectomy

Unilateral cervical sympathectomy of the month-old rat produced a condition simulating progressive facial hemiatrophy during a postoperative period of 2–4 months. While the gross extent of the lesion produced varied, the histological appearance was uniform; adipose tissue alone was diminished. Osseous, muscular and vascular structures of the facial skull appeared unaltered under these experimental conditions. No evidence of a neurotrophic influence on either the growth or maintenance of bone form was found. The mechanism of production of the adipose atrophy remains unknown.

defects in cartilage after sympathectomy

Profound degenerative changes occur in skeletal muscle following interruption of it's nerve supply and it has therefore been quite reasonably concluded that the motor nerves exert a definite trophic influence over striated muscle (Tower, 1939). However in the case of bone innervation, one is dealing with a quite different phenomenon.

unavoidable side effects and unforeseeable and unacceptable complications

symptoms of Autonomic Neuropathy closely resemble the symptoms described by many who have undergone sympathectomy

This is not unexpected. Autonomic Neuropathy is due to damage to the ANS. Sympathectomy is a surgical destruction of the sympathetic chain (part of the chain) either by cutting or clamping  - a surgery that can result in a deranged functioning of the ANS. Surgeons are allowed to market sympathectomy  as an elective (life-style) procedure, often misrepresented as a 'cure' by the ETS surgeons. Autonomic neuropathy:
"Cardiovascular symptoms: exercise intolerance, fatigue, sustained heart rate, syncope, dizziness, lightheadedness, balance problems
Gastrointestinal symptoms: dysphagia, bloating, nausea and vomiting, diarrhea, constipation, loss of bowel control
Genitourinary symptoms: loss of bladder control, urinary tract infection, urinary frequency or dribbling, erectile dysfunction, loss of libido, dyspareunia, vaginal dryness, anorgasmia
Sudomotor (sweat glands) symptoms: pruritus, dry skin, limb hair loss, calluses, reddened areas
Endocrine symptoms: hypoglycemic unawareness
Other symptoms: difficulty driving at night, depression, anxiety, sleep disorders, cognitive changes" http://www.aafp.org/afp/2005/0601/p2123.html

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.

POSTSYMPATHECTOMY PAIN AND CHANGES IN SENSORY NEUROPEPTIDES

Postsympathectomy limb pain, postsympathectomy parotid pain, and Raeder's paratrigeminal syndrome are pain states associated with the loss of sympathetic fibres and in particular with postganglionic sympathetic lesions. There is a characteristic interval of about 10 days between surgical sympathectomy and onset of pain. It is proposed that this pain in man is correlated with the delayed rise in sensory neuropeptides seen in rodents after sympathectomy. These chemical changes probably reflect the sprouting of sensory fibres and may result from the greater availability of nerve growth factor after sympathectomy. The balance between the sensory and sympathetic innervations of a peripheral organ may be determined by competition for a limited supply of nerve growth factor.

Following sympathectomy the basal t-PA activity in plasma was 70% less than controls

Following sympathectomy: (i) the basal t-PA activity in plasma was 70% less than controls (2.92 ± 1.96 versus 9.33 ± 1.72 IU/ml;P ≤ 0.001); (ii) the acute release from isolated vessels induced by bradykinin or phenylephrine was comparably reduced; and (iii) the greatest reductions occurred in densely innervated small vessel explants. The results provide new support for an autonomic regulation of neural t-PA release into the vessel wall matrix and blood of densely innervated thin-walled microvessels.

link between sympathectomy and osteoclast-mediated bone resorption

Recent investigations have demonstrated a link between sympathectomy and osteoclast-mediated bone resorption. The exact nature of this link, however, is unknown, We hypothesize that substance P, a potent vasoconstrictive neuropeptide found in peripheral sensory fibers, including those innervating bone, is the mediator of this phenomenon. To test this theory, the effects of substance P on in vitro calcium release from cultured neonatal mouse calvaria were assessed. In addition, an in vivo study was conducted whereby gerbils were injected with capsaicin to eliminate substance P-containing fibers before sympathectomy with 6-hydroxydopamine. If the effects of 6-hydroxydopamine were eliminated by prior administration of capsaicin, the role of sensory nerves in sympathectomy-induced resorption would be strongly implicated.


The results indicate that substance P is capable of inducing resorption and that substance P-containing sensory nerves are required for the induction of resorption after sympathectomy in the gerbil.

Cardiovascular collapse developing during thoracoscopic thoracic sympathectomy

Cardiovascular collapse developing during thoracoscopic thoracic sympathectomy in a patient with essential palmar hyperhidrosis: A case report.  
Park SJ, Jee DL.

Thoracoscopic thoracic sympathectomy (TTS) is usually a safe and uncomplicated procedure for treating essential palmar hyperhidrosis. However, we report a case of cardiovascular collapse that developed in a healthy patient undergoing TTS. The surgeon performed the left sympathectomy without incident. However, scarcely had an incision been made in the skin of the right chest when the patient developed sinus bradycardia and sudden, severe hypotension. Pulseless ventricular tachycardia occurred immediately thereafter, which rapidly progressed to ventricular fibrillation and cardiovascular collapse. The patient required resuscitation with 200 J of direct current shock defibrillation along with an intravenous injection of epinephrine 1 mg. She recovered without sequelae. We believe the Bezold-Jarisch reflex was triggered by pooling of venous blood and surgical stimuli, and the patient developed cardiovascular collapse as a result.

cervical sympathectomy for sexual dysfunction?

Use of stellate ganglion block for the treatment of sexual dysfunction

If the claims of the hundreds of ETS/ESB surgeons is true, than cervical or thoracic sympathectomy affects a well controlled, and limited area of the upper extremity (the hands only) to 'eliminate the overactive nerves that supply the sweat glands', - then this 'invention' registered by Lipov should be dismissed. 


Lipov here claims to prove systemic effect of the cervical procedure that will influence sexual function. Is he finally asserting what so many patients are saying and so many surgeons keep denying, that:
a: interference with the upper sympathetic chain elicited systemic changes of the nervous system
b: interference with the upper thoracic chain affected (also) sexual function - which was not beneficial to the patient. Indeed, retrograde ejaculation can be found in studies describing adverse effects of sympathectomy.

'Sweating surgery' controversy

There is tremendous controversy surrounding ETS. While prestigious medical boards such as the Society of Thoracic Surgeons fully support it, the National Institutes of Health considers ETS to be a "nerurocardiologic disorder", and NIH studies ETS patients as part of their protocol for autonomic failure. There is much disagreement among ETS surgeons about the best surgical method, opitimal location for nerve destruction, and as to the nature and extent of the consequent side effects. The internet now features many websites run by surgeons extolling the benefits of ETS backed by happy patient testimonials. However, there are also many websites run by disabled ETS victims who complain of severe complications and lack of adequate informed consent. Several online discussion forums are dedicated to the subject of ETS surgery, where both positive and negative patient testimonials abound.

FACTORS CONTRIBUTING TO SYMPATHECTOMY FAILURE

1. Sympathectomy is analogous to the act of killing the messenger. The sympathetic nervous system has the critical job of properly controlling and preserving the circulation in different parts of the body, especially in the extremities. By paralyzing the system, the extremity will be more apt to have disturbance of circulation and is left unprotected from fluctuation in circulation.

Sympathectomy is similar to permanently removing the central heat and air-conditioning system and never replacing it because of malfunction.

Sympathectomy permanently damages the temperature regulatory system. The reason sympathectomy does not cause side effects other than ineffective control of pain as well as impotence and orthostatic hypotension is because it is invariably partial and incomplete.

2. Even after "complete" removal of the sympathetic plexus for the upper or lower extremities, the sympathetic nerves in the wall of the blood vessels are left intact.

3. As shown in Table 6, the most common form (over 80%) of RSD is disuse RSD. In this situation, the sympathetic system is temporarily hyperactive. Proper conservative treatment would prevent any unnecessary invasive surgery (such as sympathectomy) in such patients.

4. Usually the patients that end up needing sympathectomy are the ones who suffer from ephaptic dystrophy. Sympathectomy in such cases cause a classic Cannon phenomenon. This physiological phenomenon refers to the fact that the end organ that is controlled by sympathetic nerve fibers  will become uninhibited in its chemical dysfunction. As a result, even though the sympathetic fibers are not contributing to acetylcholine or become uninhibited with resultant increase of pain input.

In diabetic neuropathy RSD, sympathectomy dramatically relieves the pain for the first 1 to 3 years. Then deafferentation can Cannon phenomenon set in. As a result, invariably by the second to fifth year the patient ends up with a lot more pain. Sympathetic blocks repeated every 6 to 12 months yield similar results.

In patients who have had sympathectomy, thermography shows an increase of temperature  in the focus of ephaptic nerve damage (Cannon phenomenon) with secondary increase of pain and discomfort.

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.

There is potentially a number of safety issues associated with this procedure

Australian Review of ETS surgery
"A lack of high quality randomised trial evidence on ETS means that it is difficult to make a judgment on the safety and effectiveness of this technique. There is potentially a number of safety issues associated with this procedure. ASERNIP-s suggests that a full systematic review including all available comparative and case series information, together with clinical inpuut, should be undertaken to provide up-to-date and comprehensive assessment of the safety and effectiveness of ETS." (ASERNIP-s Report No. 71, August 2009)

Reported success stories on ETS are "prone to bias and have significant methodological problems"

Australian Review of ETS surgery - 2001
The four case series were not critically appraised because they are prone to bias and have significant methodological problems. These studies represent level IV evidence according to the NHMRC criteria and one should not draw firm conclusions from their findings.

To date, the benefits or side effects associated with endoscopic thoracic sympathectomy for treating facial blushing have not been properly evaluated and reported.

Further research using a well-designed controlled trial is warranted to assess the efficacy of endoscopic thoracic sympathectomy for treating facial blushing.

The intervention leads to severe immediate complications in some of the patients

Finnish Review
Conclusions: The evidence of the effectiveness of ETS is weak due to a lack of randomized trials. The intervention leads to severe immediate complications in some of the patients, and to persistent side-effects for many of the patients.

UK Review of ETS surgery
We did not identify any controlled trials or cohort studies. The evidence about effectiveness, based on three case series, was therefore very limited. The main weakness of these studies was their lack of a comparison group and their resulting inability to exclude a placebo response to surgery. In addition, the methods of assessing outcome were poorly described and not validated, and the range of outcomes assessed was limited. The studies provided very limited evidence that sympathectomy improves blushing. Side effects were common.

inhibition of sympathetic activity and a possible impairment of endothelial function.

Alterations in skin microcirculation induced by brachial plexus block can be evaluated by wavelet transform of the laser Doppler flowmetry signal. Brachial plexus block reduces the oscillatory components within the 0.0095- to 0.021- and 0.021- to 0.052-Hz intervals of the perfusion signal. These alterations are related to inhibition of sympathetic activity and a possible impairment of endothelial function.

in one-lung ventilation (OLV), shunt fraction increases, oxygenation is impaired, and hypoxemia may occur

When switching from two-lung to one-lung ventilation (OLV), shunt fraction increases, oxygenation is impaired, and hypoxemia may occur. Hypoxemia during OLV may be predicted from measurements of lung function, distribution of perfusion between the lungs, whether the right or the left lung is ventilated, and whether the operation will be performed in the supine or in the lateral decubitus position. Hypoxemia during OLV may be prevented by applying a ventilation strategy that avoids alveolar collapse while minimally impairing perfusion of the dependent lung. Choice of anesthesia does not influence oxygenation during clinical OLV. Hypoxemia during OLV may be treated symptomatically by increasing inspired fraction of oxygen, by ventilating, or by using continuous positive airway pressure in the nonventilated lung. Hypoxemia during OLV may be treated causally by correcting the position of the double-lumen tube, clearing the main bronchi of the ventilated lung from secretions, and improving the ventilation strategy.

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.

the pineal capability of producing antigonadal substance is suppressed by cervical ganglionectomy

Pineal glands of male hamsters 8 weeks after removal of both eyes or both superior cervical ganglia and those of untreated animals were studied by electron microscopy. In the blinded hamsters the reproductive organs were remarkably involuted, whereas the pinealocytes enlarged and were characterized by a tremendous hypertrophy of the smoothsurfaced endoplasmic reticulum, in the mesh of which some dense cored vesicles were distributed. In contrast the pinealocytes of ganglionectomized hamsters atrophied and were noted by a large number of lysosomes and sparsity of the agranular reticulum, the testes being significantly larger than the controls. The findings were interpreted to be compatible with the view that the pineal capability of producing antigonadal substance is augmented by blinding and is suppressed by cervical ganglionectomy due to the impairment of normal functioning of the pineal by denervation.

Haematological changes during stress abolished by sympathectomy

To study haematological effects of emotional stress, blood samples were obtained from 29 healthy, normotensive, non-smoking males aged 20–34 years before, during and after 10 min of mental arithmetic. There were significant increases in pheripheral blood cell count, haemoglobin concentration, and haematocrit in response to mental stress. Parallel to these changes significant increases in heart rate, and systolic and diastolic blood pressure were observed. The relative increments of leucocyte (8%) and platelet (3·5%) count were significantly higher than the increase in haemoglobin concentration (2%). There was a significant positive correlation between the blood pressure increase and the mobilization of leucocytes, whereas the increase in erythrocyte count, haemoglobin concentration, and haematocrit showed significant positive correlations with heart rate reactivity. It is concluded that mental stress causes an increase in leucocyte and platelet count that could not solely be accounted for by the concurrent haemoconcentration.

The emotional leucocytosis observed in dogs has been claimed to be neurogenic in origin, since sympathectomy abolished the rise in leucocyte count (Garrey & Bryan, 19 3 5).

ETS can rarely, if ever, be used effectively to treat hyperhidrosis

There are many physicians who argue that the high risk of complications after ETS surgery, and the relatively low rates of post-ETS satisfaction as a result of these problems, mean that ETS can rarely, if ever, be used effectively to treat hyperhidrosis.
