Superficial BrachialArtery with its High Division

Abstract

The upper extremity arterial system shows a large number of variations attributed to the complex and multiple sites of their embryonic development. It is important to be aware of arterial variations in this region because upper extremity is a frequent site of injury. Moreover, brachial artery is of significance in cardiac catheterization for angioplasty, pedicle flaps, or arterial grafting. Accurate knowledge and relationships of major arterial conduits and their variational patterns is important in reparative surgery in the arm, forearm and hand. One such variation is superficial brachial artery with prevalence rate of 0.2- 25%. In this report, the brachial artery emanated normally but coursed superficial to the median nerve and about five cm above the intercondylar line, bifurcated into its terminal branches i.e. radial and ulnar artery. Keywords: brachial artery;high division; variations.
