摘要
Variant aortic arch branching pattern may occur with different embryological mechanisms. We report on a variant aortic arch branching in a 41-year old Tanzanian male cadaver during dissection practice. The left common carotid artery was seen originating from the root of the brachiocephalic trunk and the left vertebral artery from the arch of the aorta proximal to the origin of the left subclavian artery. We discuss the relative literature, its potential embryologic development and clinical significance.
