From the Guidelines
TIPS is recommended over thrombolysis for portal vein thrombosis in cirrhotic patients with portal hypertension complications.
Key Points
- In cirrhotic patients with portal vein thrombosis, TIPS creation is recommended if portal hypertension complications persist despite well-managed anticoagulant therapy 1.
- TIPS placement has been shown to achieve portal trunk recanalization and improve outcomes in patients with cirrhosis and portal vein thrombosis 1.
- The procedure is technically feasible in most cases, with a high rate of portal vein patency and TIPS patency at one year post-procedure 1.
- However, TIPS creation is associated with a risk of major complications, including hepatic encephalopathy, which occurs in around 25% of patients at one year post-procedure 1.
- Anticoagulation therapy is often used as first-line treatment, but TIPS placement may be considered if anticoagulation fails or is not effective 1.
Indications for TIPS
- Portal hypertension complications, such as ascites or recurrent variceal bleeding, that persist despite well-managed anticoagulant therapy 1.
- Cirrhotic patients with portal vein thrombosis who are awaiting liver transplantation 1.
Important Considerations
- TIPS creation should be performed by an experienced interventional radiologist or hepatologist 1.
- Patients should be fully informed of the potential complications and risks associated with the procedure 1.
- Regular follow-up and monitoring are necessary to minimize the risk of complications and ensure optimal outcomes 1.
From the Research
Portal Vein Thrombosis Treatment Options
- Transjugular Intrahepatic Portosystemic Shunt (TIPS) is a viable treatment option for patients with portal vein thrombosis (PVT) 2, 3, 4, 5
- TIPS can reduce portal hypertensive complications such as variceal bleeding and facilitate liver transplantation 2, 5
- The presence of PVT is no longer considered a contraindication to TIPS, although the procedure may be more technically difficult and should be performed in expert high-volume centers 2, 4
TIPS Placement Techniques
- Three strategies for TIPS placement have been reported:
- Portal recanalization and conventional implantation of the TIPS through the jugular vein
- Portal recanalization through percutaneous transhepatic/transsplenic access
- Insertion of the TIPS between the suprahepatic vein and a periportal collateral vessel without portal recanalization 4
- Different materials can be used as fluoroscopic targets for the TIPS needle and for portal recanalization 4
Outcomes and Complications
- TIPS has been reported with high levels of technical success, short-term portal vein recanalization, and long-term PV patency and TIPS patency outcomes 2
- Comparative studies have shown favorable outcomes of TIPS compared with non-TIPS treatment of PVT complications 2, 5
- Major procedure-related complications are rare, but can include hemorrhage and contrast extravasation 6
- Ascites, white blood cell count, and degree of portal vein tumor thrombosis are independent predictors of survival after TIPS creation 6
