When the vessel is significantly widened, it's called an aneurysm. Herein, we report the case of a neonate with aortic atresia, ventricular septal defect, type C interrupted aortic arch, and aberrant right subclavian artery who underwent Norwood stage I operation and The external carotid artery arises later as an independent vessel.
