Thoracic and vascular aspects of thoracic outlet syndrome. 1986 update

Abstract

Upper extremity symptoms of arterial or venous origin are a rarer manifestation of the thoracic outlet syndrome than those caused by brachial plexus compression. Since the authors' original report in 1967, a better understanding of the necessity for detailed history and physical examination preoperatively and advances in angiography and computed tomography have made the selection of patients for thoracic outlet decompression and vascular reconstruction more reliable. Refinement in vascular surgical techniques and the advent of effective thrombolytic therapy have made the results of therapy more consistent. First rib resection and scalenectomy are curative for the majority of patients whose symptoms are caused by compression of the brachial plexus. Removal of the embologenic focus with vascular reconstruction and thoracodorsal sympathectomy are generally required in the presence of subclavian artery compression or aneurysm producing peripheral emboli. In patients who have venous compromise, thrombectomy or thrombolytic therapy and relief of subclavian venous compression may minimize future disability.
