title: Limitations of percutaneous techniques in the treatment of portal vein thrombosis.
abstract: New therapeutic alternatives to portal vein thrombosis (PVT) include the percutaneous, transhepatic infusion of fibrinolytic agents, balloon dilatation, and stenting. These maneuvers have proven to be effective in some cases with acute, recent PVT. We have treated two patients with acute PVT via transhepatic or transjugular approaches and by using pharmacologic and mechanical thrombolysis and thrombectomy. Although both patients clinically improved, morphologic results were only fair and partial rethrombosis was observed. The limitations of percutaneous procedures in the recanalization of acute PVT in noncirrhotic patients are discussed.
