PURPOSE: It has been suggested that initial stent position in transjugular intrahepatic portosystemic shunts (TIPS) with relation to hepatic venous outflow is an important determinant of shunt patency. It was hypothesized that TIPS with the stent-implanted segments terminating in the hepatic vein (HV) have shorter primary unassisted shunt patency durations ...

During the last 15 years the transjugular intrahepatic portosystemic shunt (TIPS) procedure has become a safe and effective treatment of portal hypertension. Its major obstacle, the high rate of shunt insufficiency, is going to be solved by the availability of covered stents showing a patency rate of up to 90%. ...

Ascites is the most common complication of cirrhosis and occurs in more than half of all patients with cirrhosis. The development of ascites indicates progression of the underlying cirrhosis and is associated with a 50% 2-year survival rate. Conventional therapies used for the treatment of ascites include sodium restriction (<88 ...

The transjugular intrahepatic portosystemic shunt (TIPS) was developed in the 1980s for treatment of complications of portal hypertension. Once it was shown that the shunt could be placed with relative ease, TIPS was rapidly applied to the treatment of many of the complications of portal hypertension. These complications include actively ...
