Removal of tissue from one person’s body and placing it in another person’s body or the removal of tissue from a donor site in one’s own body and placing it in another location.
A procedure which involves taking an organ such as the heart or kidney, or tissue such as skin, and grafting it into someone to replace an organ or tissue which is diseased or not functioning properly.
The organ or tissue which is grafted.
The surgical implant of a healthy human organ or tissue to replace one that has failed or is about to fail. The organ often is taken from the body of a person who has died, if the family (or the donor when alive) agrees to make such organs available for transplants. Organs such as the heart and liver are often removed after a determination of brain death but while the donor’s heart is still functioning, since it is essential that blood supply be maintained to these organs. Sometimes the transplant tissue, such as skin or bone marrow, can come from elsewhere in the patient’s own body. In the case of some kinds of transplants, such as kidneys, the organ may be from a close living relative, such as a sibling or biological parent. This poses a risk for the relative, since he or she has only one of the important organs left, but it can be a lifesaving gift within a family. Sometimes parents face the difficult decision of whether—and under what circumstances—to approve a transplant from one of their children to another.
To move one living part of the body to another, or from one individual (the “donor”) to another. The organ or tissue transplanted is called an “allograft” if from a donor, and an “autograft” (or “homograft”) if from the same individual. The term “transplant” may also be used as a noun to indicate the tissue or organ which is transplanted.
To transfer an organ or tissue from one person (the donor) to another (the recipient) or from one body part to another to replace a diseased organ or to restore normal function. The organs most commonly transplanted are the skin and kidneys; corneal, bone, cartilage, and vessel transplants also occur, and, less commonly, heart and liver transplants. The major problem with donor-recipient transplants is the tendency of the recipient’s body to reject the transplanted tissue as foreign; donor and recipient are carefully matched by blood-typing and tissue-typing procedures (the best donors are identical twins) to minimize the chances of rejection. N. any organ or tissue transferred from one person to another or from one part of the body to another part.
To transfer tissue or an organ from one part to another (or one body to another) as in grafting or plastic surgery.
