Budd Chiari Syndrome (BCS) is a rare liver condition where the hepatic veins are narrowed or blocked due to blood clots. Due to the blockages, blood flowing into the liver has difficulty in flowing out leading to build-up of blood in the liver.

Primary Sclerosing Cholangitis (PSC) is a chronic disease of the bile ducts in the liver which become inflamed and scarred and ultimately gets blocked. As the bile ducts get blocked, it accumulates in the liver and damages the liver cells causing cirrhosis or fibrosis.

Biliary atresia is a rare disease affecting the liver and bile ducts. The condition is seen immediately after birth. In an infant or baby with biliary atresia, bile flow from the liver to the gallbladder is blocked.
