Background:
Understanding anatomical variations in the aortic arch is essential for clinical practice, particularly in cardiovascular, radiological, and surgical procedures.
Materials And Methods:
This report describes a rare variant in the branching pattern of the aortic arch, identified during cadaveric dissection of 71-year-old female at the Department of Anatomy and Histology, University of Warmia and Mazury in Olsztyn.
Results:
In this case, the left common carotid artery originated from the initial segment of the brachiocephalic trunk, resulting in a common origin of the carotid arteries. Only two branches arise directly from the aortic arch: a modified brachiocephalic trunk and the left subclavian artery.
Conclusions:
This uncommon anatomical pattern has clinical implications for accurate diagnostic imaging, surgical planning, and intervention.
