Esophageal atresia associated with a rare vascular ring and esophageal duplication diverticulum: A case report and review of the literature

Esophageal atresia with tracheoesophageal fistula (EA-TEF) associated with a right aortic arch poses a dilemma to the pediatric surgeon, often necessitating an operative approach via a left thoracotomy. A right aortic arch may be associated with a vascular ring, and EA-TEF, too, has been reported in association with a vascular ring. Rarely, esophageal atresia is associated with a second esophageal anomaly, such as a so-called “esophageal lung.” To our knowledge, there is no report of all three in one patient. We report the first case of a patient with associated EA-TEF, vascular ring (diverticulum of Kommerell), and esophageal lung. The literature is reviewed for these rare entities.
