Treatment of Budd-Chiari Syndrome with Long-Segment Hepatic Vein Thrombosis When Anticoagulation Fails to Resolve Liver Failure, Ascites, or Varices
This protocol addresses patients with Budd-Chiari syndrome caused by long-segment thrombotic occlusion of the hepatic veins who have symptoms of liver failure, ascites, or varices — and in whom initial anticoagulation-based management has not achieved the required clinical milestones at the two-week evaluation.
Clinical Scenario
Long-segment thrombotic occlusion of the hepatic veins represents a more severe form of Budd-Chiari syndrome, associated with significant hepatic and splanchnic congestion. When liver failure, ascites, or varices are present, a portocaval shunting procedure may be required to relieve congestion — and early intervention may be indicated without waiting for a response to medical treatment.
When the Previous Treatment Did Not Work
First-line management consists of anticoagulation with low-molecular-weight heparin (initiated as soon as the diagnosis is made), together with supportive medication as required. Escalation to this protocol is indicated when the two-week evaluation shows that the following targets were not reached: resolution of ascites, a negative sodium and water balance, factor 5 at least 50% of its normal value, and a decrease in conjugated bilirubin if it was initially elevated.
Next-Step Intervention (Partial Overview)
When anticoagulation alone is insufficient, early transjugular intrahepatic portosystemic shunt (TIPS) placement using a PTFE-covered stent is the intervention considered. Precise technical requirements govern the shunt diameter. In patients with additional venous thrombosis, a catheter-based adjunctive approach alongside anticoagulation is defined, with a structured monitoring schedule. The complete parameters and step-by-step algorithm are detailed in the full protocol.
Clinical Goals
The target outcomes include reduction of the portosystemic pressure gradient to approximately 10.8 mmHg and improvement of creatinine concentration to approximately 0.8 mg/dL within two weeks of the intervention.

- The long-segment thrombotic occlusion of hepatic veins, common in Western countries, is more severe and may require a portocaval shunting procedure to relieve hepatic and splanchnic congestion.
- In symptomatic patients (liver failure, ascites, varices), early TIPSs may be indicated without waiting on their response to medical treatment.
- It is strongly recommended to create a shunt with a diameter of at least 10 mm to achieve sufficient shunt flow and to relieve hepatic and intestinal congestion.
- Needless to say, only 10 mm PTFE-covered stents should be utilized to optimize flow and long-term patency.
- The TIPS reduced the pressure gradient to 10.8 ± 4.9 mmHg.
- With respect to the systemic circulation, the TIPS improved the creatinine concentration within 2 weeks from 1.9 ± 1.7 to 0.8 ± 0.4 mg/dL.
