Body
was changed:
A high division of the brachial artery is is an unusually proximal bifurcation of the brachial artery into into its ulnar and radial branches branches in the upper arm.
It is an anatomical variant of the arterial branching pattern of the upper limb.
Description
In general, the brachial artery bifurcates into its terminal branches at the level of the neck of the radius but it is not unusual to find a much earlier bifurcation of the brachial artery at the level of the coracobrachialis muscle insertion. A rare case of bifurcation of the brachial artery at its commencement below the lower border of the teres major muscle has also been described 1.
