A form of biliary cirrhosis in which small intrahepatic ducts are destroyed while the major intra and extra hepatic ducts remain patent; most patients are middle aged females and have circulating antimitochondrial antibodies.
Cirrhosis of the liver caused either by destruction of the intrahepatic bile ducts (primary biliary cirrhosis) or blockage of the extrahepatic bile ducts (secondary biliary cirrhosis).
Fibrosis of the hepatic parenchyma due to obstruction of bile flow (cholestasis) in the intrahepatic or extrahepatic bile ducts (bile ducts, intrahepatic; bile ducts, extrahepatic). Primary biliary cirrhosis involves the destruction of small intra-hepatic bile ducts and bile secretion. Secondary biliary cirrhosis is produced by prolonged obstruction of large intrahepatic or extrahepatic bile ducts from a variety of causes.
