Rare Multiple Variations in the Radial Anrtery of an Iranian Cadaver

Radial artery is a muscular artery that normally aroses from brachial artery in the elbow.The radial artery is increasingly being used as a coronary bypass graft. The aim of this paper is to report details of rare multiple variations in the radial artery of a male Iranian cadaver. In routine dissection, it was observed that the right side radial artery arose from brachial artery in the arm. It then desended toward elbow by passing under biceps brachii tendon and leaned toward lateral side of the forearm and went toward the wrist.It then curled posterolateraly round the carpus went beneath the abductor pollicis longus, extensor pollicis longus, and brevis crossed anatomical snuff box. In the proximal end of the first intermetacarpal space, radial artery had a branch for deep palmar arch, but the main trunk of artery continued toward the first web .Ultimately, by passing under the first dorsal interosseous muscle, it entered the palm and then divided into two branches that median artery had formed an anastomotic ring like a rhomboid. From this anastomotic ring two branches had separated, one for thumb and one for index finger. This variation in the route of the radial artery in hand, is the fist time to be reported and is not reported in the available data.
