Acute liver failure is a very complex type of disease with a mortality of up to 90%, leading to numerous severe disturbances of the whole organism. Bleeding because of absent synthesis of various coagulation factors and disseminated intravascular coagulation, acute kidney failure, circulatory failure with vasopressor dependence, respiratory failure with adult respiratory distress syndrome, neurological failure up to coma because of hepatic encephalopathy, and a very high risk of infection and sepsis frequently result from the initial state of isolated liver failure. High urgency liver transplantation is a highly efficient therapy if performed in time. However, increasing the rate of spontaneous recovery of the patients' own liver, and reducing the need for liver transplantation is preferable and would further improve the outcome of acute liver failure. Extracorporeal liver support by multipass albumin dialysis or plasmapheresis and filtering systems may offer a possibility to fulfill these aims of therapy. A prospective study in 88 patients with acute liver failure has shown a nonsignificant trend in improvement of survival after acute liver failure by multipass albumin dialysis and filtering. Other retrospective studies have shown benefits in improving hepatic encephalopathy and brain oedema. Further, an increase in the rate of spontaneous recovery of liver function has been described. With regional citrate anticoagulation for multipass albumin dialysis and filtering, the need for systemic anticoagulation – a potentially very harmful measure in these patients – can be eliminated and the rate of filter clotting can extremely effectively be reduced.
