Abstract
Non-operative percutaneous treatment of portal hypertension as ultima ratio therapy in liver cirrhosis has now been established in 16 cases. After transjugular puncture of a main branch of the portal vein via a liver vein, recollapse of the parachymal track after predilation was prevented by implantation of a Palmaz stent. This type of stent enables remodelling of the individual length of the parachymal track in the liver by overlapping placement of several stents. In our experience the Palmaz stent seems to be very efficient in keeping the shunt patent. First, its smooth inner surface after dilatation guarantees laminar flow within the stent as a precondition for homogeneous endothelialization of the inner surface. Second, overlapping placement of the stents allows precise covering of the individual length of the shunt. Third shunt diameters can be established by using different sized ballons. The range is 7-10 mm. Forth this type of stent has a high degree of resistance to excentric or concentric compression by the surrounding tissue.
