A rare variant of the ulnar artery with important clinical implications: a case report.

Background: Variations in the major arteries of the upper limb are estimated to be present in up to one fifth of people, and may have significant clinical implications.

Case Presentation: During routine cadaveric dissection of a 69-year-old fresh female cadaver, a superficial brachioulnar artery with an aberrant path was found bilaterally. The superficial brachioulnar artery originated at midarm level from the brachial artery, pierced the brachial fascia immediately proximal to the elbow, crossed superficial to the muscles that originated from the medial epicondyle, and ran over the pronator teres muscle in a doubling of the antebrachial fascia.
