What is TIPSS and Hepatic Vein Stenting?
Transjugular Intrahepatic Portosystemic Shunt (TIPSS) is an interventional radiology procedure that creates an artificial channel within the liver using a covered metallic stent to connect the portal venous system to the hepatic venous system. This effectively decompresses the portal circulation, reducing portal pressure and controlling life-threatening complications of portal hypertension: variceal haemorrhage, refractory ascites, and hepatic hydrothorax. Hepatic vein stenting addresses Budd-Chiari Syndrome obstruction of the hepatic veins by restoring hepatic venous outflow and preventing progressive liver failure.
Who is This Procedure For?
Transjugular intrahepatic portosystemic shunt (TIPSS) is recommended for patients with complications of portal hypertension that are not adequately controlled by endoscopic or medical therapy. It is commonly used in cases of acute variceal haemorrhage as a rescue procedure when bleeding cannot be controlled endoscopically, achieving haemostasis in over 90% of cases. TIPSS is also effective in preventing variceal rebleeding and is considered superior to endoscopic banding in selected patients, particularly those with Child-Pugh B disease or high portal pressures (HVPG >20 mmHg) after an initial bleed. It plays a significant role in managing refractory ascites that does not respond to maximum diuretic therapy, leading to substantial reduction in fluid accumulation and improved quality of life. Additionally, TIPSS is beneficial in hepatic hydrothorax, where pleural effusion due to portal hypertension persists despite medical therapy or surgical options like VATS. It is also indicated in Budd–Chiari syndrome, where hepatic vein thrombosis causes painful hepatomegaly and ascites, as the procedure helps restore hepatic venous outflow. In selected cases, TIPSS may be used for portal vein thrombosis associated with severe portal hypertension complications.
How is TIPSS Created?
-
Jugular Vein Access & Hepatic Vein Entry
Right internal jugular vein is punctured under ultrasound guidance. A catheter is advanced into the right hepatic vein under fluoroscopic guidance.
-
HVPG Measurement & Portal Vein Targeting
Baseline portal pressure is measured. Wedge venography or intravascular ultrasound (IVUS) maps the portal vein position for accurate needle targeting.
-
Transhepatic Needle Pass
A TIPSS needle is passed from the hepatic vein through liver parenchyma into the portal vein the most technically demanding step.
-
Tract Dilation & Stent Deployment
The transhepatic tract is dilated. A covered ePTFE stent (Viatorr) is deployed across the shunt tract and dilated to 8–10mm diameter.
-
Portal Pressure Reassessment
Post-TIPSS portal pressure confirms adequate reduction (target HVPG <12 mmHg). Variceal embolisation may be added if indicated.
