  • Title: Effect of portacaval shunt and arterialization of the liver on bile acid metabolism.
    Author: Horak W, Gangl A, Funovics J, Grabner G.
    Journal: Gastroenterology; 1975 Aug; 69(2):338-41. PubMed ID: 1150042.
    Abstract:
    The effect on bile acid clearance of portacaval end-to-side shunt, with and without arterialization of the hepatic portal venous bed, was studied in dogs. Portacaval shunt reduced liver blood flow by 75%, and peripheral serum bile acid concentration rose from 3 to 239 muM. Arterialization maintained total liver blood flow within physiological range and serum bile acid concentration was only 19 muM. Since hepatic bile acid extraction was similar in both groups, bile acid clearance was determined largely by total liver blood flow. The results of this study indicate that hepatic clearance of substances originating from portal blood is impaired in portacaval shunt and can be restored by increasing the arterial blood supply to the liver.
