 Living donor liver transplantation - Wikipedia, the free encyclopedia
Living donor liver transplantation (LDLT) has emerged in recent decades as a critical surgical option for patients with end stage liver disease, such as cirrhosis and/or hepatocellular carcinoma often attributable to one or more of the following: long-term alcohol abuse, long-term untreated Hepatitis C infection, long-term untreated Hepatitis B infection.
The concept of LDLT is based on (1) the remarkable regenerative capacities of the human liver and (2) the widespread shortage of cadaveric livers for patients awaiting transplant.
Historically, LDLT began as a means for parents of children with severe liver disease to donate a portion of their healthy liver to replace their child's entire damaged liver.

 Living Donor Liver Transplantation   (Site not responding. Last check: 2007-11-06)
Liver transplantation is the accepted treatment for most acute and chronic liver diseases resulting in liver failure; however, the scarcity of cadaveric donors has become an insurmountable problem limiting the application of liver transplantation (1).
In adult LDLT the right lobe (rarely the left lobe) is expected to provide enough liver mass to sustain the life of the recipient, and the donor is left with enough liver mass to recover from the donor operation.
Other advantages of LDLT are the scheduling of an elective liver transplantation, allowing time to optimize the medical condition of the recipient, and use a better quality organ coming from a healthy donor with a smaller chance of potential injury based on the shorter time in preservation solution.

Infants and small children form the bulk of paediatric patients needing a liver transplant, and the transplantation of a small amount of liver, usually the left lobe which constitutes about 35% of the liver volume, is enough to meet their metabolic requirements.
