Superficial ulnar artery diagnosed by vascular ultrasound: case report

The largest branch of the terminal division of the brachial artery is the ulnar artery, which arises after the cubital fossa. This artery usually has a deep path in the muscles of the anterior forearm and is responsible for vascularization of the superficial and deep musculature on the ulnar side of the forearm and hypothenar area of the hand. We report an anatomical variant diagnosed by Doppler ultrasound in which the ulnar artery had a superficial position in the forearm. Occurrence of a superficial ulnar artery is rare, but it is an important fact for clinicians, surgeons, and nursing professionals.
