When someone experiences the loss of a limb or severe facial disfigurement, one of their options may be vascularized composite allotransplantation (VCA), which transfers a graft containing multiple tissues transferred as a functional unit. Using VCA to restore the functionality and aesthetics of a lost upper limb or disfigured face is a profound and life-altering gift; however, the process and the decision to accept (or donate) a VCA graft is complex and deeply emotional. In addition to psychosocial considerations, a VCA recipient must commit to undergoing years of rigorous rehabilitation, have a robust support system in place, and accept and understand the risks of being on immunosuppressive drugs for the rest of their life. Despite VCA advances over the last 25 years, challenges remain, and the small number of recipients of face or hand transplants makes it difficult to generalize outcomes.
