The variations in branching pattern of arch of aorta are likely to occur as a result of the altered development of certain branchial arch arteries during the embryonic period. The incidence of origin of left common carotid artery and brachiocephalic artery from a single trunk is estimated as 7.2-21%. This kind of variations in branching pattern may present with non-specific symptoms such as dyspnoea, dysphagia, intermittent claudication. This case highlights about Brachiocephalic and left common carotid artery arose from a common trunk on the arch of the aorta in a male cadaver. The knowledge of such variations are important for interventional radiologist and surgeons to perform safe and effective thoracic surgeries.
