A Study on Branching Pattern of Arch of Aorta With Its Embryological Significance and Review of Literature

Abstract

Introduction:The Arch of Aorta normally provides three major branches from its convex surface, before descending down as the thoracic aorta. The branches arranged from right to left are the brachiocephalic trunk, the left common carotid artery and the left subclavian artery. The right common carotid artery and the right subclavian artery are given off by the brachiocephalic trunk. Any variation in the origin and arrangement of these branches are considered to be deviations from the normal process of development of the aortic arches.
