Right and left common carotid arteries arising from the branchiocephalic, a rare variation of the aortic arch.

The aortic arch may present a plethora of anatomical variations, which my cause a cluster of complications in interventional procedures in surgery and angiography. We present a rare case of a common origin of both the common carotids arteries from the brachiocephalic trunk (anonymous artery), with the left common carotid artery emerging from the initial portion of it, forming a small common trunk. The great importance towards an excellent knowledge of the topographical aortic arch anatomy is stressed out.
