Anatomical and morphometric features of the profunda brachii artery.

Abstract

When the literature is examined, studies evaluating the profunda brachii artery (PBA) are limited as most studies only investigate the artery's origin. In 44 upper extremities belonging to 24 human anatomical specimens, single and double PBAs were observed in 39 and five cases, respectively. In cases with a single PBA, the origin was the brachial artery (BA) in 35 cases and the posterior circumflex humeral artery in four cases. In cases with double PBAs, the artery's origin was the BA. Morphometric measurements of single and double arteries originating from the first branch BA were evaluated separately and compared according to sex and side. Our study, in which the PBA was examined morphologically and morphometrically, contributes to the literature anatomically and radiologically in treating humerus fractures and lateral arm-flap applications by surgeons.
