Liver transplantation for acute liver failure: a Spanish perspective.

The Spanish characteristics of organ donation (high accessibility to a transplant) and the different proportion in the etiologies of acute liver failure (ALF), namely, the very low incidence of paracetamol overdose causing this syndrome in contrast with other Western countries, are the causes of some specific features of emergency liver transplantation for ALF. The most relevant are the short time between the need for a graft and effective urgent liver transplant, and the high proportion of patients who undergo this therapy. This paper analyzes these characteristics and provides information about the use of biological and nonbiological extracorporeal liver support devices in acute liver failure, suggesting that these systems should be tested in countries with a long waiting times for urgent liver transplantation, or in patients with ALF and contraindications for transplantation.
