Transjugular intrahepatic portosystemic shunt

In medicine, transjugular intrahepatic portasystemic shunt (TIPSS) is "A type of surgical portasystemic shunt to reduce portal hypertension with associated complications of esophageal varices and ascites. It is performed percutaneously through the jugular vein and involves the creation of an intrahepatic shunt between the hepatic vein and portal vein. The channel is maintained by a metallic stent. The procedure can be performed in patients who have failed sclerotherapy and is an additional option to the surgical techniques of portocaval, mesocaval, and splenorenal shunts. It takes one to three hours to perform.

Effectiveness
TIPSS was systematically reviewed by the Cochrane Collaboration who concluded that "TIPS was more effective at removing ascites as compared with paracentesis...however, TIPS patients develop hepatic encephalopathy significantly more often"

TIPSS was better than peritoneovenous shunt in a randomized controlled trial.
