Abstrakt: Portal vein thrombosis (PVT) is an uncommon cause for presinusoidal portal hypertension and can occur even in liver-graft recipients. Interventional radiology by percutaneous approach may represent a valid and less invasive alternative to surgical treatment. We describe three cases of PVT (2 liver-transplant patients and a cirrhotic patient candidate for liver transplantation) treated by combined mechanical and pharmacologic thrombolysis. The Arrow-Trerotola device was used along with the infusion of urokinase by way of a percutaneous-transhepatic approach. In all cases, a recanalization of the portal system was obtained and maintained during the follow-up. The best result was achieved when mechanical thrombectomy was performed before urokinase infusion. The combined locoregional treatment with mechanical thrombectomy and pharmacologic thrombolysis appears to be a promising approach for PVT because of its rapid and durable effect and its ability to reduce the dose of urokinase required to achieve recanalization.
