Calculated risks

Certain complications can occur before and after a transplant. These depend upon the type of transplant, as well as upon the patient’s age and overall health.

Doctors evaluate which treatment is to be preferred for each patient on the basis of the assumed risks. They assess both the risks and the possibilities for success, and then present them to their patients, so that they may be able to make informed decisions about the form their treatment will take.

The following table summarizes the complications related to each stage of a transplant.
