Double-lumen Aortic Arch: Persistence of the Fifth Aortic Arch?

Abstract

Double-lumen aortic arch is a rare congenital anomaly related to persistence of the fifth aortic arch. It may be found alone or in association with other anatomical changes of the heart. We report a case of double-lumen aortic arch associated with coarctation of the aorta and patent ductus arteriosus in a child with a congenital malformation known as the VACTERL association (vertebral defects, imperforate anus, cardiopathy, tracheoesophageal fistula, renal abnormalities and limb anomalies).
