[Transjugular intrahepatic portosystemic shunt]

The transjugular intrahepatic portosystemic shunt (TIPS) is a relatively new method of creating a portosystemic shunt using a needle, angioplasty balloon catheters and expandable metallic stents. During a 6-month period, the authors have performed TIPS, using the spiral Z-stent--another modification of the Gianturco-Rósch stent--in 13 patients with portal hypertension. The procedure was technically successful in all patients. Portal pressure decreased by 6 mmHg in one group of patients with 9-10 mm stents, and by 12 mmHg in another group using 12 mm stents. Control of variceal bleeding or resolution of refractory ascites was evident in 11 of the 13 patients.
