a reduction of the muscular tone and to a secondary neurovascular disorder at the edge of the sympathetic denervation zone

Surgical sympathectomies and chemical sympatholyses bring about a true sympathetic deafferentation. This leads to central retrograde degenerescence reactions of the pre-ganglionic neurons, to a reduction of the muscular tone and to a secondary neurovascular disorder at the edge of the sympathetic denervation zone.

A report of a patient with an azygos lobe and an associated anomalous azygos vein covering the upper thoracic sympathetic chain. This anomaly poses a significant risk during the procedure of endoscopic thoracic sympathectomy. A chest X-ray is useful in detecting this anomaly and alerting the surgeon to potential problems.

Although bilateral sympathectomy almost totally depleted the NA from the right atrium (by 98%), the NPY-ir levels were only reduced by 50%

Unilateral and bilateral sympathectomy produced similar reductions in the concentrations of NPY-ir and NA in the ventricular tissue.
