The liver holds about one pint (13 percent) of the body’s blood supply at any given moment. The liver consists of two main lobes. These lobules are connected to small ducts that connect with larger ducts to ultimately form the hepatic duct. The hepatic duct transports the bile (fluid that helps break down fats and gets rid of wastes in the body) produced by the liver cells to the gallbladder and duodenum (the first part of the small intestine).
The liver carries out many important functions, such as:
- Making bile and producing certain proteins for blood plasma
- Changing food into energy
- Clearing the blood of drugs and other poisonous substances
- Regulating blood clotting
Reasons for the procedure
A liver transplant may be recommended for people who have end-stage liver disease (ESLD), a serious, life-threatening liver dysfunction. ESLD may result from various conditions of the liver.
The most common liver disease for which transplants are done is cirrhosis. Cirrhosis is a long-term disease of the liver in which a fiber-like tissue covers the organ and prevents toxins and poisonous substances from being removed. Other diseases that may progress to ESLD include, but are not limited to, the following:
- Acute hepatic necrosis. This is the death of tissue in the liver.
- Biliary atresia. A condition in which the bile ducts are absent or have developed abnormally.
- Metabolic disease. Conditions that affect the chemical activity in cells that are affected by the liver.
- Liver cancers. These are primary tumors (that start in the liver) that have not spread outside the liver.
- Autoimmune hepatitis. A chronic inflammation of the liver, resulting in liver cell damage and destruction.
There may be other reasons for your doctor to recommend a liver transplant.
Risks of the procedure
As with any surgery, complications can occur. Some complications from liver transplantation may include, but are not limited to, the following:
- Blockage of the blood vessels to the new liver
- Leakage of bile or blockage of bile ducts
- Initial lack of function of new liver
The new liver may not function for a brief time after the transplant. The new liver may also be rejected. Rejection is a normal reaction of the body to a foreign object or tissue. When a new liver is transplanted into a recipient’s body, the immune system reacts to what it perceives as a threat and attacks the new organ, not realizing that the transplanted liver is beneficial. To allow the organ to survive in a new body, medications must be taken to trick the immune system into accepting the transplant and not attacking it as a foreign object.
Contraindications for liver transplantation include, but are not limited to, the following:
- Current or recurring infection that cannot be treated effectively
- Metastatic cancer. This is cancer that has spread from its primary location to one or more additional locations in the body.
- Severe cardiac or other medical problems preventing the ability to tolerate the surgical procedure
- Serious conditions other than liver disease that would not improve after transplantation
- Noncompliance with treatment regimen
- Alcohol consumption
There may be other risks depending on your specific medical condition. Be sure to discuss any concerns with your doctor prior to the procedure.
Liver Transplantation –
Liver transplantationis the replacement of a diseased liver with a healthy liver from another person. The liver may come from a deceased organ donor or from a living donor. Family members or individuals who are unrelated but make a good match may be able to donate a portion of their liver. This type of transplant is called a living transplant. Individuals who donate a portion of their liver can live healthy lives with the remaining liver.
An entire liver may be transplanted, or just a section. Because the liver is the only organ in the body able to regenerate, a transplanted portion of a liver can rebuild to normal capacity within weeks.
The donor liver is transported in a cooled salt-water (saline) solution that preserves the organ for up to 8 hours. The necessary tests can then be done to match the donor with the recipient.
The new liver is removed from the donor through a surgical cut in the upper abdomen. It is placed into the patient who needs the liver (called the recipient), and attached to the blood vessels and bile ducts. The operation may take up to 12 hours.
- Uncontrolled metastatic cancer outside liver
- Active drug
- Alcohol abuse
- Active septic infections
- Infection with HIV
Liver donor requirements –
Any member of the family, parent, sibling, child, spouse or a volunteer can donate their liver. The criteria for a liver donation include:
- Being in good health
- Having a blood type that matches or is compatible with the recipient’s
- Being between 18 and 60 years old
- Being of similar or bigger size than the recipient
- Before one becomes a living donor, the donor must undergo testing to ensure that the individual is physically fit.

The most commonly used technique is orthotopic transplantation, in which the native liver is removed and replaced by the donor organ in the same anatomic location as the original liver.The transplant operation can be conceptualized as consisting of the hepatectomy (liver removal) phase, the anhepatic (no liver) phase, and the postimplantation phase. The operation is done through a large incision in the upper abdomen. The large majority of liver transplants use the entire liver from a non-living donor for the transplant, particularly for adult recipients. A major advance in pediatric liver transplantation was the development of reduced size liver transplantation, in which a portion of an adult liver is used for an infant or small child. Further developments in this area included split liver transplantation, in which one liver is used for transplants for two recipients, and living donor liver transplantation, in which a portion of a healthy person’s liver is removed and used as the allograft. Living donor liver transplantation for pediatric recipients involves removal of approximately 20% of the liver.
