Acute Portal Vein Thrombosis in Cirrhosis When Anticoagulation Has Not Achieved Recanalisation
This protocol addresses acute portal vein thrombosis (PVT) in patients with cirrhosis who have already received anticoagulation therapy but have not achieved portal vein recanalisation — the defined threshold for escalating to the next treatment step.
Clinical scenario: Acute PVT in the setting of cirrhosis. In patients with cirrhosis who are potential liver transplant candidates, the management of PVT carries direct implications for transplant feasibility and outcomes, making the choice of treatment strategy particularly consequential.
Why the previous treatment was insufficient: First-line anticoagulation — with low-molecular-weight heparin or vitamin K antagonists (direct oral anticoagulants applicable in selected patients depending on liver functional reserve) — did not achieve the treatment goal of portal vein recanalisation. Failure to reach this target is the criterion that triggers escalation to this protocol.
Next-step approach (partial overview)
When anticoagulation alone has not recanalised the portal vein, an interventional portosystemic shunting procedure may be considered as the next step. The complete protocol — including patient selection criteria, contraindications, and the full evidence-based approach — is available via the link below.

- In patients with cirrhosis and PVT who are potential LT candidates, anticoagulation should be used regardless of degree of occlusion or extension of PVT, to improve feasibility and outcomes of LT.
- In patients with cirrhosis and PVT who have complications of portal hypertension, such as variceal bleeding or recurrent ascites, TIPS may be considered over anticoagulation alone to reduce morbidity.
- In patients with cirrhosis and PVT which progresses despite anticoagulation, TIPS may be considered over anticoagulation alone to reduce morbidity.
