Blood coagulation alterations after embolic occlusion of the renal circulation.
Alterations in blood coagulation and fibrinolysis after embolic occlusion of renal adenocarcinoma were investigated in 11 patients. Peripheral vein blood was collected before, 2 hours after and on the first, third and fifth to seventh day after embolization. Five patients had renal vein blood sampling before and 2 hours after embolization. Increased levels of fibrinogen, plasminogen and antiplasmin were found on days 1-3. Antithrombin III showed a slight decrease between days 1 and 3 after embolization. All measured variables were lower in renal vein compared with simultaneous samples from peripheral vein. In renal vein samples, consumption of antiplasmin and antikallikrein was indicated. Fibrinopeptide A (FPA) was increased, with a mean maximum 2 hours after embolization. The findings seemed mainly to monitor acute phase reaction but also activation of blood coagulation and fibrinolysis. Embolization might be used as a human model of coagulation activation and acute phase reaction.
