Vascularized Sural Nerve Graft, Fascial Free Flap, and Regenerative Peripheral Nerve Interface in the Setting of Recurrent Thigh Liposarcoma: A Case Report.

Background: There is no clear consensus in the literature regarding clinical indications for vascularized nerve grafts. Most studies indicate that vascularized nerve grafting, rather than non-vascularized nerve grafting, is indicated for nerve gaps of greater than 7 cm. Vascularized nerve grafts are superior to non-vascularized nerve grafts because they possess an independent blood supply.
