Unusually high bifurcation of the brachial artery: analysis of variants, clinical implications, and case report

A high division of the brachial artery is a relatively common anatomical variation, occurring in 10.05% of the population, and therefore requires special attention during surgical and diagnostic procedures. Its most frequent variant is the division of the brachial artery into a brachioradial artery and a brachioulnar artery. The presence of this variation can affect the efficacy and safety of procedures such as angiography, vascular surgeries, or reconstructive surgeries. Further research should aim to standardize the descriptions of anatomical variations in upper limb arteries and establish a unified nomenclature system.
