perforating branches

per·fo·rat·ing branch·es

arterial branches that penetrate a wall or pass from the anterior to the posterior aspect or compartment of a structure such as the hand or foot to anastomose or be distributed. Terminologia Anatomica lists perforating branches of the following: 1) deep palmar arch (rami perforantes arcus palmaris profundi [TA]); 2) fibular artery (ramus perforans fibularis [TA]); 3) internal thoracic artery (rami perforantes arteriae thoracicae internae [TA]); 4) anterior interosseous artery (ramus perforans arteriae interossei anterioris [TA]); and 5) plantar metatarsal arteries (rami perforantes arteriarum metatarsearum plantarium [TA]).
Synonym(s): ramus perforans [TA]

In 2% of our cases, the early branches (MCA cortical branches given before it trifurcates or bifurcates) were given off before the perforators; The MCA perforating branches arose from the superior trunk of a bifurcated MCA in one of these cases.

Along the course in the middle zone, numerous small dorsolateral and dorsomedial perforating branches take off at irregular points form the RA and provide perfusion for the muscles, fascia and skin of the forearm.

This maneuver will expose the fine dorsolateral and dorsomedial perforating branches, and should be done gently not to risk branch avulsion.
