Variation of Superficial Palmar Arch: A Case Report

The hand in the humans is abundantly supplied by the blood by two anastomotic arches, there are superficial and deep palmar arch. The knowledge of variations in the arterial supply of hand has reached the practical importance. Superficial palmar arch is an arterial arcade and a dominant vascular structure in the palm. These two arcades are formed by the anastomosis between two main arteries of forearm ie. radial and ulnar artery and their branches. Superficial palmar arch is defined as the anastomosis between superficial branch of ulnar artery and superficial palmar branch of radial artery with the ulnar artery as the main feeding vessel. Superficial palmar branch shows variation in formation at the radial side. In this study we have recorded the variation which would help in clinical and surgical implications.
