1.   Furthermore the hepatic vein wedge pressure-inferior vena caval mean pressure gradient was normal.

2.   The right or middle hepatic vein was then catheterised under fluoroscopic screening and thetip of the sheath advanced into the hepatic veing.

3.   Portography showed that the two stents inserted did not completely cover the parenchymal tract between the portal and hepatic veins and occlusion had occurred.

4.   This was successfully treated by the insertion of a Palmaz stent within the hepatic vein.

5.   The tube is placed between the portal and hepatic veins in the liver to relieve high blood pressure that can occur within a diseased organ.
