[Free vascularized nerve transplants, free donor nerves, suitable donor sites].

The vascularized nerve graft offers an alternative to the conventional free nerve graft. Possible nerves for grafting, the anatomy of the donor sites, and the advantages and disadvantages of vascularized nerve grafts are discussed. The variations in blood supply and the loss of function caused by harvesting play an important role. Clear indications in our opinion are long nerve defects, scar in the wound bed and reconstruction of the brachial plexus. Exact planning, correct indications and good micro-neurovascular technique are all important in neuromicrosurgery and the basis for good results.
