Venous graft as temporary arteriovenous shunt in free tissue transfer.
A new method of interpositional venous graft in microvascular tissue transfer is described. The interpositional vein is transferred to the vessels of the recipient site primarily, forming an arteriovenous shunt. Later, when the microanastomosis to the flap is created, the shunt is divided into an arterial branch and a venous branch. This method reduces the ischemic time of the free flap and allows the use of interpositional grafts of optimal length.
