Scalp replantation by arterialised venous network flow-through.

A successful clinical case of scalp replantation is presented where a suitable artery could not be identified in the amputated part. Reperfusion of the flap was achieved by an arteriovenous inflow anastomosis and a conventional venous anastomosis for drainage. The aesthetic and physiological success of this case suggests that arteriovenous scalp replantation is a potential avenue for treatment where arterio-arterial repair is not possible. The possible explanation for the success in this patient is the paucity of valves that exist in the venous network of the scalp and forehead, noted in our previous anatomical studies. Knowledge of the replanted tissue venous architecture provides an anatomical basis to understand the potential limitations of arteriovenous replantation.
