A case of a rare aortic arch variation: the avian form

Abstract

Variations in the branching pattern of the aortic arch are multiple. The avian form is an extremely rare anatomical variation with only a few reported cases in the literature. Herein we report a case of avian variation with two branches arising from the aortic arch: a bicarotid trunk and a common origin for bilateral subclavian arteries.
