Dorsal sympathectomy and management of thoracic outlet syndrome with VATS.
Dorsal sympathectomy and the management of the thoracic outlet syndrome have been considerably improved with the use of video assistance because it affords both magnification and an improved light system. Two techniques of video assistance were employed in the group of patients described here. One involved the sympathectomy done through three ports using standard video-assisted thoracic surgical methods. The second technique involved a transaxillary incision with removal of the first rib using video-assistance magnification and light, operating either directly or secondarily while visualizing the image on the television set. (The vast majority of cases have been performed using this latter technique.) Major indications for performing dorsal sympathectomy include (1) hyperhidrosis, (2) Raynaud's phenomenon, (3) Raynaud's disease, (4) causalgia, (5) reflex sympathetic dystrophy, and (6) vascular insufficiency of the upper extremity. Except for hyperhidrosis, all of the other indications require the usual diagnostic techniques, including cervical sympathetic blockade to assess whether the symptoms are relieved by temporary blockade of the sympathetic ganglia. In 326 patients, sympathectomy, performed either alone or in conjunction with first-rib removal for relief of the thoracic outlet syndrome, has been successful. In only 6 patients has sympathetic activity recurred in less than 6 months. Initially all of them were treated conservatively. Three of the 6 required a repeat sympathectomy. Postsympathectomy neuralgia occurred in only 2 of more than 326 patients. Both cases were managed successfully in a conservative fashion. Among the patients in whom a Horner's syndrome was not deliberately induced, the syndrome developed in 2. In both, the syndrome resolved spontaneously within several months.
