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.
