A rare type of interruption of the aortic arch: case report

Abstract

ventricular septal defect, patent duc­ tus arteriosus, bicuspid aortic valve, left ventricular outflow tract obstruc­ tion, or aortopulmonary window2. The IAA anomaly was first described by Steidele3 in 1778. Celoria and Patton4 later classified IAA into three types according to the site of dis­ continuity of the aortic arch. Type A was the IAA where the site of discon­ tinuity was distal to the left sublcav­ ian artery, type B, between the left carotid and left subclavian arteries and between the innominate and left carotid arteries, type C. The most common type is B (53%), followed by A (43%) and C (4%). We describe a type A IAA that coexists with bila­ teral hydroureter and a foramen secundum.
