A rare case of double variation of the aortic arch («bovine arch» and aberrant left vertebral artery)

The aim of this study was to examine the variant anatomy of the brachiocephalic arteries and their branches with the registration of the most known morphometric parameters. The study material was impersonal computerized tomography angiograms of a rare case of variant anatomy of the brachiocephalic arteries of a 58-year-old female. During our work we identified such a phenomenon as «bovine arch» and aberrant left vertebral artery branching off from the aortic arch. The discovery of such a finding during surgery without a thorough preliminary examination of the patient can create certain technical difficulties for the surgeon
