A 3-day-old infant underwent 16-slice contrast-enhanced CT for further evaluation of interruption of a right aortic arch with ambiguous branching identified antenatally. Volume-rendered reconstruction viewed from the right anterior and craniocaudal viewpoint (Fig. 1) and cephalad viewpoint (Fig. 1) clearly demonstrated the right and left common carotid arteries arising from the small ascending artery (arrows) and the interrupted aortic arch. Both subclavian arteries (dotted arrows) arose from the superior aspect of the descending aortic segment. There was a persistent sixth aortic arch (or persistent ductus arteriosus) that supplied the right descending aorta from the main pulmonary artery.
