Fig. 1 (A) Incision commences 3 cm above the level of the wrist joint along a line lateral to the tendon of the flexor carpi ulnaris in the direction of the medial epicondyle before curving forward toward the bicipital tendon, terminating 3 to 4 cm below the elbow joint. (B) Surgical exposure of the left ulnar artery in the anterior compartment of the left forearm. Note the flexor digitorum superficialis is retracted laterally and the flexor carpi ulnaris is retracted medially to expose the ulnar artery. (C) The lower half of the ulnar artery has been mobilized and the pedicle has been dissected proximally by separation of the flexor carpi ulnaris from the flexor digitorum superficialis. In the upper third of the forearm, the ulnar artery leaves the ulnar nerve and is shown lying on the flexor digitorum profundus before passing beneath the median nerve and the flexor digitorum superficialis and overlying the palmaris longus and flexor carpi radialis. (D) Harvesting of the ulnar artery is completed by clipping and dividing the artery distal to the median nerve, immediately below the origin of the common interosseous artery.
