Liver transplant

Liver transplant is a treatment option for some people with liver cancer and for people with liver failure whose condition can't be controlled with other treatments. Liver failure may happen quickly or over a long period of time. Liver failure that occurs quickly, in a matter of weeks, is called acute liver failure. Acute liver failure is an uncommon condition that is usually the result of complications from certain medications. Although a liver transplant may treat acute liver failure, it is more often used to treat chronic liver failure. Chronic liver failure occurs slowly over months and years. Chronic liver failure may be caused by a variety of conditions. The most common cause of chronic liver failure is scarring of the liver (cirrhosis). When cirrhosis occurs, scar tissue replaces typical liver tissue and the liver doesn't function properly. Cirrhosis is the most frequent reason for a liver transplant. Major causes of cirrhosis leading to liver failure and liver transplant include: Hepatitis B and C. Alcoholic liver disease, which causes damage to the liver due to excessive alcohol consumption. Nonalcoholic fatty liver disease, a condition in which fat builds up in the liver, causing inflammation or liver cell damage. Genetic diseases affecting the liver. They include hemochromatosis, which causes excessive iron buildup in the liver, and Wilson's disease, which causes excessive copper buildup in the liver. Diseases that affect the tubes that carry bile away from the liver (bile ducts). They include primary biliary cirrhosis, primary sclerosing cholangitis and biliary atresia. Biliary atresia is the most common reason for liver transplant among children. Liver transplant may also treat certain cancers that originate in the liver.
