Abstract

Purpose

Portal vein thrombus (PVT) can worsen portal hypertension and hepatic decompensation in patients with cirrhosis and impact liver transplant outcomes. This retrospective case series describes large bore mechanical thrombectomy of PVT with the Inari FlowTriever device during, or remotely after, transjugular intrahepatic portosystemic shunt (TIPS) placement.

Materials and Methods

Ten patients with PVT were treated with large bore thrombectomy. All patients had underlying cirrhosis, complicated by portal hypertension with acute/subacute PVT. Thrombectomy was performed either with TIPS placement, or via a previously placed thrombosed shunt. Median time from TIPS placement to thrombectomy was 3 years.

Results

Thrombectomy was technically successful in all patients with a majority achieving complete resolution of PVT in a single session. During mean follow-up of 13.3 months, all patients achieved complete resolution of PVT without recurrence.

Conclusion

Large bore mechanical thrombectomy together with TIPS is a feasible and effective treatment of acute/subacute PVT in cirrhotic patients with portal hypertension, often with complete resolution in a single session.
