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.

Apart from the terminal branches, the branches of the brachial artery in the arm are profunda brachii, superior ulnar collateral artery, inferior ulnar collateral artery, muscular branches to the surrounding muscles and a nutrient branch to the humerus [1].
The superior ulnar collateral artery arose from the distal part of the brachial artery whereas the inferior ulnar collateral branch arose from the proximal part of the ulnar artery in the arm instead of arising from the brachial artery [fig3].
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.
In its further course the common trunk at the commencement of the radial groove gave the profunda brachii branch and it continued further down along with the ulnar nerve to end by giving superior and inferior ulnar collateral branches in the arm (Fig.
The profunda brachii, superior and inferior ulnar collateral arteries were normal in their origin and course.
2003) observed the termination of deep brachial artery as inferior ulnar collateral artery in the middle of the arm.
