title: [Vascular rings: surgical treatment].
abstract: From 1982 to 1992, nine patients underwent correction of vascular rings. The diagnosis was strongly suggested by symptoms of tracheoesophageal obstruction and was confirmed by barium esophagogram and angiography. Endoscopic studies were considered unnecessary and potentially harmful. Seven patients had double aortic arch, one patient right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum and one patient anomalous origin of the left pulmonary artery. The anomaly was approached through a left thoracotomy in every patient. There were no operative or late deaths. When patients are symptomatic, vascular rings should be promptly repaired. The surgical risk is minimal, and the long term results are excellent.
