The suprascapular artery: case report of an unusual origin.

A case is presented where certain branches of the right subclavian artery had unusual origins. The thyrocervical trunk was missing, the transverse cervical artery occupying its place. The inferior thyroid artery arose from the common carotid, and the suprascapular from the dorsal scapular artery. Pertinent literature on the suprascapular artery is reviewed.
