origin, brachial; distribution, arm muscles at back of elbow; anastomoses, anterior and posterior ulnar recurrent, superior ulnar collateral, profunda brachii, and recurrent interosseous, as part of the articular vascular plexus of the elbow.

inferior ulnar collateral artery

one of a pair of branches of the deep brachial arteries, arising about 5 cm from the elbow, passing inward to form an arch with the deep brachial artery, and carrying blood to the muscles of the forearm. Compare superior ulnar collateral artery.

The inferior ulnar collateral vessels as well as muscular branches to the biceps, brachialis, or triceps muscle may require ligation depending upon the location and position of the tumor in order to mobilize the brachial vessels away from the neoplasm.
The inferior ulnar collateral artery provides direct vascularization to the nerve, with no anastomosis in the region just proximal to the cubital tunnel.
5) Anterior transposition significantly decreases the potential for nerve compression/ tension during elbow flexion; however, the procedure itself may devascularize the nerve by interfering with the intraneural circulation-namely, elimination of existing multiple mesentery-like vessels, especially those originating from the inferior ulnar collateral artery.
