title: Anomaly of the portal vein with total ramification of the intrahepatic portal branches from the right umbilical portion: CT features.
abstract: OBJECTIVE
  To describe CT findings of portal vein anomaly with total ramification of the intrahepatic portal branches from the right umbilical vein.
  
  
  METHODS
  Retrospective analysis was performed in 6 patients with portal vein anomaly with total ramification of the intrahepatic portal branches from the right umbilican vein. We analyzed the position of the umbilical portion of the portal vein and ligamentum teres, and determined the intrahepatic branching pattern of the portal vein.
  
  
  RESULTS
  The umbilical portion and ligamentum teres were deviated to the right and seen above the gallbladder fossa in all 6 patients. All major braches of the portal vein ramified from the right umbilical vein in all 6 patients.
  
  
  CONCLUSIONS
  The possibility of this portal vein anomaly should be kept in mind when hepatic resection or partial liver transplantation is required.
