Endoscopic transthoracic for upper limb hyperhidrosis: Limited does not reduce postoperative compensatory sweating:
"Sympathectomy is a technique about which we have limited knowledge, applied to disorders about which we have little understanding." Associate Professor Robert Boas, Faculty of Pain Medicine of the Australasian College of Anaesthetists and the Royal College of Anaesthetists The Journal of Pain, Vol 1, No 4 (Winter), 2000: pp 258-260
Cell body reorganization in the spinal cord after elective surgery to treat palmar sweating
The amount of compensatory sweating depends on the patient, the damage that the white rami communicans incurs, and the amount of cell body reorganization in the spinal cord after surgery.
Other potential complications include inadequate resection of the ganglia, gustatory sweating, pneumothorax, cardiac dysfunction, post-operative pain, and finally Horner’s syndrome secondary to resection of the stellate ganglion.

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.

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: "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.

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)"

Seven cases of enlargement of the 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.
