An arterialized venous flap is a cutaneous flap based solely on subcutaneous veins. The flap is perfused by nonphysiologic flow of blood from the vein into the peripheral tissue. This nonphysiologic perfusion limits the indications for an arterialized venous flap, and its postoperative complications make it an unpopular choice for reconstruction. When venous flaps are designed following the direction of venous valves (antegrade) in a flow-through fashion, the blood may bypass the peripheral tissue without perfusing the flap. A higher pressure within the efferent end of the vein impedes venous return from the peripheral tissue into this draining vein. Thus, venous congestion of the arterialized venous flap becomes inevitable. We describe our approach to designing an arterialized venous flap in which direct arteriovenous shunting is largely eliminated, thereby transmitting a higher pressure in the periphery of the flap while maintaining a physiologic venous pressure in the efferent vein. This restriction of shunting can be accomplished in a number of ways, depending on the venous pattern within the flap.
