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

JBR-BTR. Nov-Dec 2014;97(6):349-50. doi: 10.5334/jbr-btr.131.


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.
