[Complex anomaly of the origin of supraaortic vessels].

We present a congenital variation of the origin of the supraaortic trunks discovered on an angioscan and described here for the first time in the literature. This variation combines a common carotid trunk, an arteria lusoria and an aberrant origin of the vertebral arteries, from the common carotid artery on the right side and from the aortic arch on the left. This complex anomaly is asymptomatic like most of the arterial variations but its detection is useful, even essential preoperatively, in order to adapt the intervention and limit potential complications.
