  • Title: Recanalized umbilical vein in portal hypertension.
    Author: Aagaard J, Jensen LI, Sørensen TI, Christensen U, Burcharth F.
    Journal: AJR Am J Roentgenol; 1982 Dec; 139(6):1107-10. PubMed ID: 6983253.
    Abstract:
    Experience with splenoportography suggests that patency of the umbilical vein occurs in about 9% of the patients with portal hypertension. A widely patent umbilical vein might serve as a decompressive portosystemic shunt. Percutaneous transhepatic portography was performed in 107 patients with cirrhosis of the liver and portal hypertension. A patent umbilical vein was found in 28 patients (26%). This finding significantly paralleled the number and size of other collateral veins, apart from gastroesophageal varices. No significant relation was found between umbilical vein patency and portal pressure, extrahepatic shunting, variceal bleeding, or ascites. It is concluded that a large patent umbilical vein does not effectively relieve portal hypertension, prevent gastroesophageal varices, or protect against variceal bleeding or ascites.
