title: [Changes in coagulation parameters during the clinical courses of recipients of living-related partial liver transplantation].
abstract: We had rare opportunities to examine changes in fibrin degradation products (FDP)-D-dimer (DD), thrombin-antithrombin III complex (TAT), plasmin-alpha 2-plasmin inhibitor complex (PIC) and other coagulation parameters during the clinical courses of living-related partial liver transplantation (LRPLT). In seven out of eight recipients without severe rejection and/or disseminated intravascular coagulation (DIC), FDP-DD values reached their maximum at 5 to 10 days after transplantation, then gradually decreased. On the other hand, TAT values rose to the maximum at anhepatic or reperfusion phase of liver transplantation. These data represent hypercoagulation in consequence of tissue thromboplastin activation after extensive operation. Changes in PIC, tissue-type plasminogen activator, and plasminogen activator inhibitor-1 (PAI-1) in the clinical course of case 1 suggested that fibrinolysis was suppressed by relatively elevated level of PAI-1 around the operation, but thereafter was adversely accelerated by relatively lower levels of PAI-1. In comparison with patients with DIC, TAT was much higher but PIC was significantly lower in recipients of LRPLT. These findings indicated that marked hypercoagulation and mild to moderate hyperfibrinolysis occurred in recipients of LRPLT.
