The arteries of the upper limbs are situated in a deep plane and are the favourable sites for intra-arterial cannulation.During routine dissection of the left turbo air m3f24-1-n upper limb of a 52-year-old female cadaver, we observed a superficial arterial pattern which was of superficial brachio-ulno-radial type.The right upper limb of the same individual chainsaw file did not show any abnormal arterial pattern.This superficial arterial system was also associated with a palmar type of median artery.The clinical significance of the anomalous arterial system of the upper limb is discussed.
