Coexisting of aortic arch variation of the left common carotid artery arising from brachiocephalic trunk and absence of the main branches of right subclavian artery: a review of the literature.

The variations in the aortic arch and its branches are of surgical interest. Many anomalies of the aortic arch and great vessels are uncovered as serendipitous findings on imaging studies, in the anatomy laboratory, or at surgery. A 56-year-old woman had an arch angiogram as part of an evaluation for cardiovascular disease. A two-vessel left aortic arch was identified consisting of the brachiocephalic trunk and left subclavian artery. In this study, we present a case of the left common carotid (LCC) artery arising from the brachiocephalic trunk (BT) and absence of the main branches of right subclavian artery in her angiographic imaging findings. There is no previous report about LCC artery arising from BT and absence of the main branches of right subclavian artery in the same person.
