Sympathetic chain ganglia are responsible for delivering information to the rest of the body regarding stress situations and the fight or flight response

Sympathetic chain ganglia are responsible for delivering information to the rest of the body regarding stress situations and the fight or flight response. These sympathetic ganglia are the structures that are destroyed during a sympathectomy

After sympathectomy in rats there is an increase in osteoclast-mediated bone resorption as well as an increase in the number of osteoclasts on the sympathectomized side

Paper: Osteoclastic Activation In Periapical Lesions After NPY Knockout (IADR/AADR/CADR 87th General Session and Exhibition (April 1-4, 2009)): "After sympathectomy in rats there is an increase in osteoclast-mediated bone resorption as well as an increase in the number of osteoclasts on the sympathectomized side compared to the control. These findings suggest an inhibitory effect of the SNS on bone resorption via osteoclasts. Our objective was to determine if an SNS mediator, neuropeptide Y (NPY), affects osteoclastic activity after pulpal exposure."

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.

Depletion of peripheral sympathetic noradrenaline led to significant decrements in escape and avoidance responding

PsycNET - Option to Buy: "Chemical sympathectomy and avoidance learning in the rat.
By Di Giusto, E. L.; King, M. G.
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)"

Right sympathectomy was associated with a 372% increase in PI (p < 0.0001), and left sympathectomy with a 316% increase in PI

Oximetry-derived perfusion index for intraop... [Ann Thorac Surg. 2005] - PubMed - NCBI: "Baseline oximetric waveforms were adequate in all subjects. Right was associated with a 372% increase in PI (p < 0.0001), and left with a 316% increase in PI (p < 0.029). This occurred as early as 1 minute after transection of the sympathetic chain. The PI in the reference probes as well as the hemodynamics remained constant."

Link between skin innervation and neuropathic pain

Nerve conduction studies for large-diameter motor and sensory nerves were normal. This report documents a pure small-fibre sensory neuropathy after prolonged use of linezolid, and the relationship between skin innervation and corresponding neuropathic pain.

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.

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 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)"
