Isolated right subclavian artery with interrupted aortic arch, ventricular septal defect, and left ventricular outflow tract obstruction

World J Pediatr Congenit Heart Surg. 2015 Apr;6(2):298-300. doi: 10.1177/2150135114566100.

Abstract

We present two cases of isolated right subclavian artery from the right pulmonary artery (PA) associated with interrupted aortic arch, ventricular septal defect, left ventricular outflow tract obstruction, and 22q11 microdeletion. Both patients were successfully managed with bilateral PA banding initially followed by a modified Yasui operation. Isolation of the subclavian artery is rare but should always be taken into account, especially when bilateral PA banding is considered. The banding must then be placed on the PA distal to the origin of the subclavian artery.
