Liver transplantatation- an overview.

Liver transplantation is a therapeutic option of choice for acute and chronic end-stage liver disease. Indications, contraindications, and surgical procedures for the liver transplantation have become well established. In most part of the world, the main source of liver for transplantation remains the donation after brain death (DBD), but in view of increasing death on the waiting list due to shortage of brain dead organs other options such as split liver transplantation, living donor liver transplantation (LDLT), and donation after cardiac death (DCD) have been used. In the pretransplantation era, liver failure was nearly universally fatal, with mortality from fulminant hepatic failure of 80-90 %, and 1-year mortality in decompensated cirrhosis of more than 50 %. In contrast, liver transplantation patient survival is presently more than 85 % at 1 year and more than 70 % at 5 years, emphasizing the clinical benefit of liver transplantation for either acute or chronic liver failure.
