Summary

In recent years liver transplantation was shown to be the only clinically effective method of treating acute or chronic hepatic failure due to various causes. However, this ultimate therapeutic approach is limited by the growing disparity between organ donation and the number of patient on the waiting list.

Factors such as high cost, morbidity, and the need for lifelong immunosuppression accelerated the research on alternative methods to support the failing liver. Recently, new technologies incorporating hepatocytes and extracorporal circulation devices were introduced for liver support systems and their role in the treatment of acute liver failure.
