Fibrinolytic study in plasma and ascitic fluid of cirrhotic patients before and after ascites concentration; reinfusion technique.

Management of cirrhosis with massive ascites involves particular difficulties. The introduction of a peritoneovenous shunt and reinfusion of concentrated ascitic fluid techniques allows increased diuresis and improves renal function. However, these procedures have frequently been associated with disseminated intravascular coagulation and/or activation of fibrinolysis. Factor VIII activity, antigen and ristocetin cofactor, plasminogen, antiplasmin, plasminogen activator activity and plasmin-antiplasmin complex were investigated both in the ascitic fluid and plasma of cirrhotic patients before and after the concentration-reinfusion technique. Our results indicated that no hyperfibrinolysis was seen in the plasma of cirrhotic patients and that activation of fibrinolysis exists in ascites. Significantly higher levels of plasmin-antiplasmin complex and plasminogen activator activity were found in ascitic fluid than in plasma. In post-reinfusion much higher levels of all three Factor VIII components were observed in cirrhotic plasma than in normal plasma. In conclusion, activation of fibrinolysis could explain coagulation complications occurring after ascites reinfusion. Antifibrinolytic treatment could render the concentration-reinfusion technique more acceptable.
