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.

The profunda femoris artery (PFA) represents the first and largest branch of the femoral artery in the thigh. A series of anatomical variations are reported, mostly concerning its point of origin and its altered trajectories within the lower limb. We present a rare case of a double PFA, where each separate branch followed the expected arterial pattern. Our case aim to alert surgeons and radiologists for the possibility to encounter an unexpected vascular alternation. Knowledge of topographical anatomy of the PFA and its variations is essential for possible complications after interventional procedures to be avoided.

Bone variations are usually a result of abnormal ossification during embryonic life. Separately or in combination, sternal foramina and bifid xiphoid process are well documented skeletal alternations, as well as the median cleft of the posterior arch of the atlas. However, their appearance in combination is not yet celebrated in the literature. Our post-mortem examination unearthed such a triple variant of an adult male skeleton, which included no other skeletal variations. The fact that all variants are depicted in the median line of ossification implies a hypothesis of a triggered midline bone defect process. The awareness among clinicians of such variations during interventional and imaging procedures is of great importance.
