Cell body reorganization in the spinal cord after surgery to trea sweaty palms and blushing

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.

After severing the cervical sympathetic trunk, the cells of the cervical sympathetic ganglion undergo transneuronic degeneration
After severing the sympathetic trunk, the cells of its origin undergo complete disintegration within a year.

Ethanol-induced cardiac hypertrophy: effects of peripheral sympathectomy

Increases in relative cardiac weight were evident in hearts from sympathectomized animals after 4 days of sympathectomy, and this change reached significance in the hearts from 6-hydroxydopamine-treated rats after a further 2 days on the control diet. Hearts from animals exposed to ethanol showed a marked, rapid development of cardiomegaly; after 24 h there was an increased mass of some 17%, which was sustained over the remaining 24-h period. The proportion of cardiac protein did not differ in the large hearts from ethanol-treated animals and those from their controls, hence myocardial oedema could not account for the increase in weight.

"sympathectomy highlighted the disparity between what is known in practice and what appears in the literature"

The March 2004 edition was quite outstanding, with an excellent editorial reminding the reader that only good results are published. The review on thoracoscopic sympathectomy highlighted the disparity between what is known in practice and what appears in the literature. 
‘Know Your Results’, the topic of the ASGBI Annual Scientific Meeting, is of outstanding importance; what is more, the surgeon has to go on knowing his/her results to ensure standards of practice do not slip.
The Journal appreciates comments and criticism and the correspondence column remains a crucial part of the BJS in its interaction between editors and reader. It is also part of the scientific process.
A more robust and incisive criticism of articles known to be flawed would prevent the retractions that have recently been published in the Lancet.

The effect of bilateral sympathectomy was significantly greater than that of unilateral sympathectomy

The effect of bilateral sympathectomy was significantly greater than that of unilateral sympathectomy. Unilateral and bilateral sympathectomy produced similar reductions in the concentrations of NPY-ir and NA in the ventricular tissue. In contrast dissimilar changes were produced in the atrium. Although bilateral sympathectomy almost totally depleted the NA from the right atrium (by 98%), the NPY-ir levels were only reduced by 50%. These results indicate that approximately half the content of NPY in the right atrium is not present in sympathetic noradrenergic neurones.

sympathectomy induced morphological alterations in the masseter muscles

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. These findings indicate that sympathetic innervation contributes to the maintenance of the morphological and metabolic features of masseter muscle fibres.

Bilateral cervical sympathectomies should be avoided because of the destruction of cardioaccelerator tone


Chylothorax as complication of sympathectomy

Chylothorax has been reported as a complication of wide range of other operations, including esophagoscopy, stellate ganglion blockade, thoracic sympathectomy, high translumbar aortography, lung resection, thyroid surgery, and spinal surgery.
