@akdwyer, Welcome to Connect and thanks for your question. We have asked your questions to one of our transplant surgeons. One person can technically receive as many organs as they need, however, multi-organ transplants are rare, particularly those involving heart and lungs, and multi-organ transplants are only performed by a small number of institutions in the country. Mayo Clinic performs multi-organ transplants on patients who require more than one organ. The organs in a multi-organ transplant do not have to all come from one donor, but you are correct, the donor has to be a match to the recipient. In the case of kidney/pancreas transplant, the kidney can come from a living donor and the pancreas comes from a deceased donor. In other multi-organ transplants from deceased donors, only one donor is used for all the organs for a single recipient.
I hope this information helps answer your questions. Have a wonderful day!
