| Summary: | Introduction. The field of composite tissue allotransplatation became a clinical reality since first hand
transplant performed in 1998 at Lyon, France and has been progressing over the past two decades. Vascularized composite allotransplantation (VCA) is now performed for life enhancing indications in a selected
group of patients under institutional protocols.
Aim. This paper is an attempt to review the outcomes of VCA to date.
Method. Analysis of relevant publications of composite tissue allotransplantation was performed, including the International Registry on Hand and Composite Tissue Transplantation (IRHCTT).
Results and discussion. To date, there are more than 200 composite tissue allograft transplants performed worldwide, including upper limb, face, larynx, trachea, abdominal wall, lower limb, penis, and
uterus. The technical aspects of VCA are no longer the factors limiting the widespread application of this
treatment modality in the clinical setting. The feasibility of the procedure has been established, and the functional outcomes have been very good so far. The major challenge is at the immunologic level, long-term goal
being to promote donor-specific tolerance and to avoid the toxicity of immunosuppression.
Conclusions. Vascularized composite allografts transplatation is a viable treatment option well on the
way of becoming a standard of care for those who have lost extremities and suffered large tissue defects. The
initial ethical dilemmas and concerns of safety and feasibility have been overcome recently and with further
standardized surgical and immunological protocols the field is likely to grow significantly in the future. |
