[The rejection of a hepatic graft].

Hepatic graft rejection is an epiphenomenon of liver transplantation. Despite the immunosuppressive therapy, nowadays a level of 30-50% of acute rejection and 5-15% chronic rejection is always persisting. Graft rejection prophylaxis essentially represents the result of a subtle equilibrium of the chronic immunosuppression. This study presents the essential data concerning the graft rejection, such as: prevalences, classifications, clinical presentation and diagnostic, both anatomopathological and differential. Modern therapy of hepatic graft rejection is also presented.
