Coagulation disturbances following ascites recirculation.
To investigate the effects of extra-corporeal ascites recirculation on coagulation, several coagulation variables were measured in ascitic return fluid and plasma before, during and after this procedure in 16 patients with diuretic resistant ascites. Small but significant reductions in plasma fibrinogen levels and platelet counts and increases in plasma X-oligomer were observed during and after the procedure compared with before. These findings are consistent with the view that ascites recirculation induces disseminated intravascular coagulation although this would appear to be only mild and of no clinical significance in the majority of patients. Although increased levels of activated factor VII were observed in ascitic fluid indicating activation of the extrinsic pathway of coagulation, a significant increase in plasma activated factor VII during the procedure was not demonstrated. Increased fibrinolytic activity was observed in ascitic fluid due to the presence of tissue plasminogen activator. Increased X-oligomer levels were observed in ascitic fluid indicating that lysis of cross-linked fibrin is also an active process within ascites.
