Endoscopic VATS sympathectomy: the uniportal technique.

Presentation of the uniportal VATS sympathectomy technique: through a single port incision, a videothoracoscope, a diathermy hook and, if needed, a lung grasper are introduced into the pleural cavity. Upon identification of the sympathetic chain, the relevant ganglia are divided. By extending laterally the dissection, the aberrant accessory sympathetic nerve fibers are also severed. Anatomic variations are illustrated and an overview of the literature is presented.
