Postductal Origin of the Left Carotid, Left Subclavian, and Aberrant Retroesophageal Right Innominate Arteries in Truncus Arteriosus with Interrupted Aortic Arch

Abstract

A neonate presented to the C.S. Mott Children’s Hospital at the University of Michigan with truncus arteriosus and interrupted left aortic arch, with associated postductal origin of the left carotid, left subclavian, and aberrant retroesophageal right innominate arteries. In addition, the patient was diagnosed with DiGeorge syndrome. This unique anomaly has not been previously reported. The anatomy, pathophysiology, embryology, and successful surgical management of this anomaly are reviewed in this report.
