A single donor may contribute numerous blood products and types of MPHO. Particularly after death, the altruistic act of a single donor or donor family may yield different musculoskeletal soft tissue and bone allografts as well as various organs such as kidneys, liver, lungs, heart, pancreas, bowel, and large vessels associated with an organ. Such tissue grafts are widely used by a variety of different surgical specialties. A recovery from a single donor may provide corneas for the ophthalmologist, vessels such as vein grafts and arterial conduits for the vascular surgeon, heart valves or vessels for the cardiovascular surgeon, tissue such as dura mater, bone, and nerve grafts for the neurosurgeon, soft tissue grafts for reconstructive bladder suspension by the urologist, skin soft tissue and bone for reconstructive procedures by the plastic surgeon. Therefore, the risk of a transmissible communicable disease from one single donor through organs and tissues crosses many medical specialties and can involve many recipients.
