BACKGROUND: The brachial artery provides the main arterial supply to the arm and is the continuation of the axillary artery. It is critical that potential morphological and structural variations be taken into consideration in everyday surgical practice as a lack of awareness could lead to fatal consequences. The major variations in the arterial patterns reported are the higher origin of radial and ulnar arteries. CASE REPORT: During dissection of right part of the upper limb, I found brachial artery as it courses with the median nerve which was crossing posterior surface of the brachial artery in the arm. The brachial artery was found bifurcating at middle third of the arm, into radial artery and the ulnar artery. When pharyngeal arches form during the fourth and fifth weeks of development, each arch receives its own artery. These arteries, the aortic arches, arise from the aortic sac, the most distal part of the truncus arteriosus. CONCLUSION: Implication of this anatomical variation is very important to conduct clinical procedures particularly, orthopaedic, plastic and vascular surgeries.
