the unilateral high bifurcation of the brachial artery

The upper limb vascular pattern shows a significant number of diversities in the arterial or venous system. although variations are usually found in the forearm region, the brachial artery variations are less common. in this report, we described a rare case of a higher bifurcation level of the brachial artery giving rise to the radial and ulnar arteries at the middle portion of the arm. it is crucial for surgeons or even radiologists to be familiar with the diverse morphological patterns of the brachial artery and its branches. moreover, they should be aware of latent hazards in the therapeutic procedures to diminish surgical complications while operating on the upper extremities.
