Acute liver failure and living donor liver transplantation.
Acute liver failure (ALF) is defined by the presence of hepatic encephalopathy due to severe liver damage in patients without pre-existing liver disease. Although the mortality of ALF without liver transplantation is over 80%, the survival rates of ALF patients have improved considerably with the advent of liver transplantation, up to 60-80% in the last decade. Living donor liver transplantation (LDLT), which has mainly evolved in Asian countries where organ availability from deceased donors is extremely scarce, has also improved the survival rate of ALF patients. According to recent reports, the overall survival rate of adult ALF patients who underwent LDLT is 60% to 90%. Although there is still controversy regarding the graft type, the optimal graft volume, and ethical issues of defining the indications for LDLT in ALF patients with respect to donor risk, LDLT has become an established treatment option for ALF in areas where the use of deceased donors organs is severely restricted.
