From Jan. 1988 to May 1990, five cases with a right-sided umbilical portion (UP) of the portal vein were found with prospective ultrasound (US) study in 2210 patients. Two out of five patients with right-sided UP had hepatic lesions. One patient had a hepatocellular carcinoma and multiple anomalies including a preduodenal portal vein, the absence of the vena cava inferior at the hepatic portion, polysplenia, intestinal malrotation, annular pancreas and a left-sided gall bladder. Another patient had an intrahepatic hematoma caused by a traffic accident. In the three patients without hepatic lesions, the right-sided UP of portal vein was found accidentally. Careful hepatic surgery was necessary to avoid injury in patients with a right-sided UP of the portal vein.
