Variations in the arterial pattern of the upper limb have been observed frequently, either in the routine dissections or in clinical practice. The aim of the present study was to describe the anatomical, surgical and embryological importance of major arteries of upper limbs of human beings. The present article is the report of low division and trifurcation of brachial artery and abnormal course of radial artery (passing deep to the pronator teres muscle) found in a 45-year-old embalmed male cadaver. Knowledge of the arterial variations in the upper limb is of considerable importance during invasive and non-invasive investigative procedures or orthopedic, reconstructive, or surgical procedures.
