Video-assisted sympathectomy for essential hyperhidrosis: effects on cardiopulmonary function.

Background: Essential hyperhidrosis is characterized by overactivity of the sympathetic fibers passing through the upper-dorsal ganglia (second and third thoracic ganglia [D2-D3]), and the treatment of choice is video-assisted thoracoscopy sympathectomy. Alterations in cardiopulmonary function after treatment have been reported.

Study Objective: To evaluate cardiopulmonary function impairment after sympathectomy in patients with essential hyperhidrosis.
