The object of this study was to determine the frequency and characteristics of altered paraumbilical vein in the hepatic parenchyma, developed from portal hypertension, using computed tomography (CT). Two hundred and ninety‐two patients who presented with portal hypertension from 1986 to 1996 were studied retrospectively. The pathway of the dilated para‐umbilical vein was demonstrated by contrast‐enhanced CT. Thirty‐one (11%) patients had a dilated para‐umbilical vein arising from the left portal vein into the falciform ligament. In 24 (77%) of these patients, the para‐umbilical vein followed the expected route, passing through the fissure of ligamentum teres hepatis. The remaining seven patients (23%) displayed the unusual pathway, with the vein arising from the left branch of the portal vein and passing into the hepatic parenchyma. In these seven patients, four had one collateral vein, and three patients had two collateral veins in the liver parenchyma. The dilated para‐umbilical vein frequently passes through the hepatic parenchyma in patients with portal hypertension.
