Case histories of 53 patients with surgically treated vascular rings are presented. The diagnosis was strongly suggested in all patients by symptoms of tracheoesophageal obstruction and was confirmed by barium esophagogram, which showed typical bilateral and posterior indentations in the esophagus. Angiography was rarely used although it is helpful in doubtful cases. Endoscopic studies were considered unnecessary and potentially harmful. A left posterolateral thoracotomy afforded ample access for division of the ring in all patients. Two patients died who were operated upon during the early experience. There were no postoperative deaths among the last 45 consecutive patients. All survivors had excellent symptomatic relief although complete resolution of symptoms took several months in some patients. The importance of early diagnosis and prompt surgical division is emphasized.
