    Abstract:
    This study was aimed at describing some technical features of the transjugular portosystemic shunt (TIPS). December 1991 to November 1993, fifty-five TIPS were performed in our department. The right internal jugular vein, which is the most direct path to the inferior vena cava, was punctured in 48 cases, the left one in seven cases. The right suprahepatic vein was catheterized in 43 cases, and the median suprahepatic vein in 12 cases. The puncture of the portal vein was performed in 21 cases in the right portal branch, in the left one in 23 cases, and in the portal bifurcation in 11 cases. In all cases in which the puncture site was questionable, an X-ray exam with lateral or oblique projection was performed, to be sure that the needle had entered the intrahepatic portion of the portal vein. A landmark to locate the portal system, such as a catheter in the hepatic artery, a skin landmark or a metallic coil near the porta, were positioned in 30 patients. Particularly, in 20 patients, a 0.018-inch guidewire with platinum tip was placed at the bifurcation; in seven cases a 3F catheter was advanced over the guidewire, to visualize the portal bifurcation directly with contrast medium injection. In our experience, a total number of 83 stents were positioned in 55 patients: 53 Wallstents, 13 Palmaz stents, and 17 Strecker-Nitinol stents. One single stent was placed in 31 patients, two stents in 21 patients, three stents in two patients, and, finally, four stents were positioned in one patient. In our series the technical success rate was 100%. The use of a metallic landmark significantly decreased procedures duration, ranging 40 minutes to 2 hours, and, above all, it allowed for significantly fewer puncture attempts, which varied from a minimum of 1-2 in 80% of cases, to a maximum of 20 especially in these patients with ascitis and with small and hard liver.
