Superficial Brachial Artery Continuing into the Forearm as a Radial Artery: Case Report

A rare variation of the brachial artery (BA) on the right upper limb was discovered during routine anatomical dissection.The axillary artery bifurcated into two large-sized blood vessels above the teres major muscle -superficial brachial artery (SBA) and deep brachial artery (DBA).The SBA passed between the roots of the median nerve and continued as the radial artery (RA) in the forearm.The deep brachial artery (DBA) was a continuation of the axillary artery (AA).It traversed behind and lateral to the median nerve and in the cubital fossa it turned into the ulnar artery (UA).Detailed knowledge of the variations of the vessels' branching pattern is essential for providing accuracy during vascular diagnosis, reconstructive surgery, and in the evaluation of angiographic images.
