How big a risk does a transplant represent?

We indicate transplantation only in those patients whose disease is not curable in another, less risky way because transplants, especially allogeneic, are connected with a not negligible risk of post-transplant complications that can lead to the transplanted person’s serious harm or death. The patient’s organs can be damaged during preparative regimen, the graft can react against the host in an acute or chronic form, a severe (bacterial, fungal, viral) infection can develop, organs can be damaged under the influence of medications, and a whole number of other complications can occur.
