Coexistence of carotid trunk and aberrant right subclavian artery originating close to left subclavian artery in tetralogy of fallot-A rare aortic arch branching anomaly.

ABSTRACT

We hereby present a patient with tetralogy of Fallot in whom a carotid trunk and aberrant right subclavian artery (arising just next to the origin of the left subclavian artery) were diagnosed on computed tomography (CT) angiography. We aim to highlight the role of CT angiography in identifying these rare aortic arch branching anomalies, which are crucial information for the operating surgeon.
