Truncus bicarotics with arteria lusoria - A rare incidental finding with clinical implications

Abstract

Arteria lusoria, an aberrant right subclavian artery originating distal to the ostium of carotid arteries, is the most common congenital aortic arch anomaly. It is commonly associated with other congenital anomalies of the heart and great vessels resulting from embryologic malformation of the aortic arch, including truncus bicaroticus, which is a common trunk of bilateral common carotid arteries. The association between arteria lusoria and truncus bicaroticus is about 29%. We reported a rare case of truncus bicaroticus with arteria lusoria in a 40-year-old male patient detected incidentally during coronary angiography through the right radial approach.
