Múltiples variaciones arteriales en el miembro superior derecho de un cadáver caucásico masculino

Abstract

Anatomical variations of the arterial patterns in the upper limb have been describe in many anatomical studies, but the occurrence of four variations in a ipsilateral upper limb is rare. These arterial variations were observed in the right upper limb of a 65-year old Caucasian male cadaver during routine dissection in the anatomy department, College of Medicine at the King Saud University, Riyadh. These arterial variations include: 1) a large common trunk of the axillary artery giving origin to subscapular artery, profunda brachii artery, common circumflex humoral artery and superior ulnar collateral artery, 2) superficial brachial artery; 3) superficial brachioulnar artery, and 4) the radialis indicis branch from superficial palmar arch. Appreciation of variations in the upper limb vessels is important due to increasing number of procedures both diagnostic and therapeutic as in breast cancer surgery, flap harvesting and arteriogaphy.
