Allotransplantation
Allotransplantation
Allotransplantation (pronounced: al-lo-trans-plan-ta-tion) is a medical procedure where organs, tissues, or cells are transferred from one individual to another of the same species.
Etymology
The term "allotransplantation" is derived from the Greek words "allos" meaning "other" and "transplantation" meaning "the act of planting in another place".
Procedure
In an allotransplant, the donor and recipient are genetically different, although they belong to the same species. This is in contrast to autotransplantation, where the donor and recipient are the same individual, and xenotransplantation, where the donor and recipient belong to different species.
Allotransplants are commonly performed for conditions such as kidney failure, liver disease, and heart disease. The success of the procedure depends on the compatibility between the donor's and recipient's Human Leukocyte Antigen (HLA) system, which is determined through HLA typing.
Risks and Complications
The main risk associated with allotransplantation is graft-versus-host disease (GVHD), where the transplanted cells attack the recipient's body. Other potential complications include transplant rejection, infection, and organ failure.
