Background:
Three patients with portal hypertension and gastrointestinal bleeding due to non-cirrhotic portal vein thrombosis were treated with portal venous recanalization transjugular intrahepatic portosystemic shunt (PVR-TIPS) via a trans-splenic access.
Main Body:
A "bottoms-up" retrograde puncture of the right hepatic vein was performed using a re-entry catheter to gain access to the right hepatic vein. In all patients a successful retrograde puncture of the right hepatic vein was achieved, thereby restoring the splenoportal tract.
Conclusion:
Our cases present an alternative approach to treat chronic portal vein thrombosis expanding the possibilities of the PVR-TIPS procedure.
