Web23 de mar. de 2024 · Transjugular intrahepatic portosystemic shunt ( TIPS or TIPSS) is a treatment for portal hypertension in which direct communication is formed between a hepatic vein and a branch of the portal vein, thus allowing some proportion of portal flow to bypass the liver. The target portosystemic gradient after TIPS formation is <12 mmHg. Webdecompression of the liver in elevated pressure. 4.
