Anatomical variation of high brachial artery bifurcation: A case report

Abstract

INTRODUCTION: Anatomical variation of high brachial artery bifurcation and these morphological variations of the brachial artery should be considered by surgeons when performing procedures in the brachial artery area. CASE: The left anterior arm and anterior forearm regions of a thirty-three-year-old cadaver was dissected. The origin, course, and terminal branches of the Brachial artery were traced. It was then observed that the Brachial artery bifurcation was in the upper third of the humerus instead of the cubital fossa. CONCLUSION: Brachial artery and its terminal branch variations are less common. However Brachial artery could be bifurcated and then reunite. In this case, the brachial artery presented bifurcation one laterally and another one medially with the median nerve running between them. Both branches don’t reunite but continue laterally and medially, respectively.
