Aortic arch origin of the left external carotid artery and type II proatlantal fetal anastomosis

AJNR Am J Neuroradiol. 2003 Mar;24(3):323-5.

Abstract

This case report demonstrates a rare vascular pattern of a left external carotid artery (ECA) that arises directly from the aortic arch (AA), along with a type II proatlantal-vertebral artery anastomosis. Our research shows no report of an ECA arising from the AA. This, in association with a type II proatlantal anastomosis, is interesting because of its apparent rarity.
