ABSTRACT
Introduction: The variation in the aortic arch is well known and it has been demonstrated by number of researchers. Changes involved in the development of aortic arch system such as regression, retention or reappearance result in the variation in branching pattern of aortic arch. Variations of the branches of aortic arch are due to alteration of branchial arch arteries during embryonic period. The most common classical branching pattern of the aortic arch in humans comprises of three great vessels, which includes Brachiocephalic trunk, Left Common Carotid artery and Left Subclavian artery.
Aim: The study is to determine the embryological basis correlating with clinical application and surgical procedures.
Materials and Methods: A study was conducted in 50 formalin fixed cadaveric hearts, during a period of two years. In the routine dissection for 1st MBBS and also museum specimens we encountered 3variations in the branches of arch of aorta.
Results: The variations in aortic arch branching pattern were observed in 4 cadaveric hearts (8%).
Conclusion: The wide spectrum of variation in the human aortic arch and its branches offer valuable information to catheterize in endovascular surgery for diagnostic and surgical procedures in the thorax, head and neck regions.
Key words: Aortic Arch (AA), Left Common Carotid (LCCA), Left Subclavian (LSA), Brachiocephalic Trunk (BCT), left vertebral artery(LVA).
