Role of parallel transjugular intrahepatic portosystemic shunts in patients with persistent portal hypertension.
Transjugular intrahepatic portosystemic shunts (TIPS) were placed in 93 patients between June 1990 and January 1992 for treatment of variceal hemorrhage. In each case, a Wallstent (Schneider USA, Minneapolis) was used to support the hepatic parenchymal tract between the hepatic and portal veins. Currently, these stents have a maximal diameter of 10 mm. In eight of 93 patients, major portal hypertension persisted after placement of a 10-mm-diameter shunt, manifested by continued rapid variceal filling and elevated portosystemic gradients. A second TIPS was placed parallel to the first in these patients to allow further portal decompression. In two other patients, a second TIPS was placed because the initial shunt functioned suboptimally. The mean postprocedural portosystemic gradient in the patients who received one TIPS was 10.2 mm Hg +/- 3.7. In patients who received two TIPS, the mean postprocedural gradient was 19.1 mm Hg +/- 3.8 after placement of the first TIPS and 12.5 mm Hg +/- 3.5 after placement of the second. Two patients developed their first episode of encephalopathy after placement of two TIPS. The methods and indications for placing two TIPS in this select population are discussed.
