Esophageal Atresia and Diverticulum of Kommerell

Diverticulum of Kommerell is an outpouching from the descending aorta that, along with an aberrant subclavian artery and ductus arteriosus, may form a vascular ring compressing the trachea and/or the esophagus. It has been reported as an incidental finding as well as the cause of persistent dysphagia, cough, “asthma,” or airway compromise at various ages but has never been reported as a cause of esophageal atresia in a newborn. We present a newborn with diverticulum of Kommerell, a vascular ring, and esophageal atresia.
