ABSTRACT 

Background: The literature documents variations in the branching pattern of aortic arches. If not identified at the right time, these variations may lead to complications during cardiovascular surgeries or invasive procedures like angiography. Surgeons working around these variations must be well-oriented.

Methodology: the present study was conducted on 103 formalin-fixed cadavers, and their branching pattern was noted.

Results: We observed five different branching patterns in the arch of the aorta. The classical three-vessel branching pattern was noted in 70.87% of cadavers. The next common pattern was two branches arising from the arch, with the brachiocephalic trunk and left common carotid artery sharing a common origin. The left subclavian artery originated as a separate branch from the arch.

Conclusion: Around 30% of Indian individuals may show variant branching patterns of the aortic arch. This should be considered during angiography, aortic instrumentation, supra-aortic thoracic, head and neck surgery, etc. This may prevent possible complications during surgeries.

Keywords: Embryology, Intervention, Intersegmental, Variant, Thyroglossal.
