Donor liver attachment

Liver transplant is surgery to replace a diseased liver with a healthy liver.

Hepatic transplant; Transplant - liver

The donated liver may be from:

• A donor who has recently died and has not had liver injury. This type of donor is called a cadaver donor.
• Sometimes a healthy person will donate part of his or her liver to a patient. This kind of donor is called a living donor. The liver can regrow itself. Both people usually end up with fully working livers after a successful transplant.

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 diseased liver is removed from the donor through a surgical cut in the upper abdomen. It is placed into the patient who needs the liver, and attached to the blood vessels and bile ducts. The operation may take up to 12 hours. The patient will have to receive a large amount of blood through a transfusion.

When your liver is healthy it performs more than 400 jobs each day, including:

• Making bile, which is important in digestion
• Making proteins that help with blood clotting
• Removing or changing bacteria, medications, and toxins in the blood
• Storing sugars (glycogen), fats, iron, copper, and vitamins

The most common reason for a liver transplant in children is biliary atresia.

The most common reason for a liver transplant in adults is cirrhosis. Cirrhosis is scarring of the liver that prevents the liver from working well. It can worsen to liver failure. The most common causes of cirrhosis are:

• Long-term infection with hepatitis B or hepatitis C
• Long-term alcohol abuse (See: Alcoholic liver disease)

Other illnesses that may cause cirrhosis and liver failure include:

• Autoimmune hepatitis
• Hepatic vein blood clot (thrombosis)
• Liver damage from poisoning or medications
• Problems with the drainage system of the liver (the biliary tract), such as primary biliary cirrhosis or primary sclerosing cholangitis
• Metabolic disorders of copper or iron (Wilson's disease and hemochromatosis)
