When the inferior vena cava is obstructed, collateral veins enlarge, connecting with the inferior (acessory) right hepatic vein (IRHV) and thence through various hepatic veins to the right atrium. Three such cases are described. In one patient, most contrast material flowed into the IRHV and from there to the left hepatic vein. The second patient had several large collaterals arising from the IRHV and flowing into the right and middle hepatic veins, while the third patient demonstrated anastomoses between the IRHV and the middle hepatic vein. All of these hepatic venous shunts eventually drained into the right atrium. There were no clinical manifestations such as ascites, edema, or dilatation of the abdominal veins. Cavography alone or combined with computed tomography proved to be diagnostic in the assessment of these intrahepatic collaterals.
