title: Vascular ring due to left aortic arch and right descending aorta.
abstract: Two children presented with symptoms suggestive of a vascular ring. Barium esophagrams in each case showed a posterior impression caused by a retroesophageal aortic arch. Angiographic studies defined a rare form of vascular ring resulting from an ascending left-sided aorta, a descending right-sided aorta and a right-sided ligamentum arteriosum. At surgery, the diagnosis was confirmed and the anomaly was corrected in each patient. Left pulmonary anomalies were present in each patient.
