The survival of a newborn with an interrupted aortic arch and a closed ductus arteriosus.

Interrupted aortic arch is a rare congenital cardiovascular anomaly with a wide spectrum of anatomical and clinical presentation. We report the case of a newborn presenting at 11 days of age with a type B-2 aortic arch interruption, a closed ductus arteriosus, and an unusual large collateral vessel arising from the ascending aorta proximal to the right carotid artery and joining an aberrant right subclavian arising from the descending aorta.
