Unilateral presenece of superficial ulner artery: A case report.

The variations in the arterial pattern of upper extremities are not uncommon. During routine dissection of right upper extremity of 55 years old male cadaver we found brachial artery gave an unusual branch, a superficial ulnar artery (SUA), just before its termination into radial &ulnar arteries. It ran superficial to the bicipital aponeurosis & muscles of front of forearm. The knowledge of variation in arterial pattern of upper limb is of great importance since many surgical and invasive procedures are performed on it. Also the course of SUA makes it prone for inadvertent intra-arterial injections misinterpreting it as vein. So nurses, medical students & clinicians should be aware about this variation.
