%X The occurrence of variations in human arterial branching of the upper limb has been commonly reported in peer-reviewed literature. However, the variability of upper limb arterial patterns may be underappreciated in medical practice, which can result in clinical and surgical errors. Here we report a case of a rare, unilateral arterial variation of the left upper limb of a 76-year-old Caucasian male cadaver, discovered during a routine educational dissection. Observed characteristics of the variation include a high brachial artery bifurcation into a superficial brachioulnoradial artery and brachial artery continuing as the interosseous artery and then a bifurcation of the superficial brachioulnoradial artery into a superficial radial and a superficial ulnar artery, which eventually contribute to the formation of the superficial palmar arch. The anatomical characteristics, prevalence, embryological origin, and clinical significance of the variation are discussed.
