Abstract

Introduction :Variation in the origin of radial artery is one of the common anomalies in the upper limb. However, distal part of its course shows a constant pattern. The knowledge of variations of the radial artery is of importance in vascular and reconstructive surgeries. Here, we report the unusual superficial course and branching of the radial artery in the forearm and the dorsum of the hand. Case report: The radial artery gave its superficial palmar branch 8 cm above the proximal border of the flexor retinaculum. After giving the superficial branch, it passed on to the dorsal aspect of the hand, by winding round the lateral aspect of the wrist superficial to the tendons forming the boundaries of anatomical snuff box and reached the first interosseous space. It passed between the two heads of the first dorsal interosseous muscle to enter the palm. Conclusion :The knowledge of this variation of the radial artery is important while performing intravenous cannulations and plastic surgeries. It is also important to cardiothoracic surgeons as the radial artery is increasingly being used for the coronary bypass graft in place of the great saphenous vein.
