Abstract

Composite tissue allografts (CTA) are also called "reconstructive transplantation" as they are a valid alternative approach to repairing complex tissue defects. These procedures are still considered "experimental" and their therapeutic value remains to be validated. An immunosuppressive treatment similar to that used in solid organ transplantation allows CTA survival and function despite a high rate of acute rejection (AR) episodes. Clinical experience seems to confirm that skin is the most antigenic tissue and the first target of AR episodes reversing the functional reorganization induced by the amputation. Appropriation of the graft occurs in parallel with functional recovery. The patients' compliance is essential for the success of CTAs as well as careful recipient selection and patient follow-up to prevent complications of long-term immunosuppression.
