Figure 1 A sausage-shaped balloon catheter is positioned in the inferior vena cava (IVC) under fluoroscopic guidance. Inflation of the balloon with contrast medium results in hepatic venous outflow occlusion from the hepatic veins (HVs). The HDAd is administered by injection through a percutaneously positioned hepatic artery (HA) catheter. Fluoroscopic image of balloon inflation with contrast medium from baboon 16855 is shown on the left. Fluoroscopic image of injection of contrast medium into the HA from baboon 11891 is shown on the right.
