Vascular variation of the radial forearm flap: a case report.

Anomalies of the radial forearm flap have been reported; however, rarely does one encounter variations that jeopardize the vascular supply of the flap. In the reported case, an anomalous superficial vessel in the forearm supplied the skin island of the radial forearm flap. In addition, there were no perforating vessels from the radial artery.
