title: Origin of the radial and ulnar arteries: variations in 81 arteriograms.
abstract: In a retrospective review of 81 upper extremity arteriograms, 8 (9.8%) origin anomalies of the major arteries were detected. High origin of the radial artery from the brachial artery was the most frequent variation, found in 7 (8.6%) cases representing 87.5% of all variations in this series. In one case, the left ulnar artery originated from the axillary artery, accounting for 12.5% of the variations. These anomalous origins of the upper extremity arteries can be explained on the basis of the embryologic development. It is important for the surgeons and radiologists to be aware of the possible arterial variations in order to prevent complications during surgical and diagnostic procedures.
