Thoracic outlet syndrome. Results of 282 transaxillary first rib resections

Thoracic outlet syndrome may follow trauma but also may be seen as a result of postural abnormalities of the shoulder girdle. Cervical ribs and other anatomic variations are not prerequisites for the diagnosis, although they may be more common in patients with thoracic outlet syndrome. The diagnosis is made by history and physical examination. There is no reliable laboratory diagnostic test to confirm or exclude the diagnosis. Proper selection of candidates for surgery can produce excellent and good results in a high percentage of cases. The transaxillary approach to first rib resection is tolerated well, and serious complications should be unusual when the procedure is performed by an experienced surgeon. Postoperative attention to shoulder girdle mechanics is important in the prevention of recurrence of symptoms and treating them should they occur.
