| hyperacute rejection | A rejection that usually develops in less than one hour from the implantation of a vascular graft, a form of antibody-mediated, usually irreversible damage to a transplanted organ, particularly the kidney, manifested predominantly by diffuse thrombotic lesions, usually confined to the organ itself and only rarely disseminated, for skin allograft rejection of this type, see white graft. (05 Mar 2000) |
| hyperacute rejection |
The immediate killing (as soon as blood flows through vessels) of a transplanted organ, seen to occur in a patient who has preformed antibodies to the donor flowing in his or her blood stream.

| hyperacute r. |
graft rejection occurring immediately after transplantation and resulting from the presence of preformed, circulating cytotoxic antibodies against antigens (often non-HLA antigens) on the graft. Antigen-antibody complexes on vascular endothelium initiate an Arthus-type reaction (type III reaction) in which complement activation results in infiltration by neutrophils, endothelial injury, and occlusion of capillaries with fibrin-platelet thrombi; adequate blood flow to the graft is never established.
