Endovascular Treatment of an Unusual Membranous Obstruction of the Inferior Vena Cava in Budd-Chiari Syndrome Complicated by Mural Portal Vein Thrombosis.

We describe the case of a patient with Budd-Chiari syndrome who presented with an unusual membranous obstruction of the inferior vena cava complicated by massive portal vein thrombosis (PVT). The patient underwent percutaneous transluminal balloon angioplasty through the right groin and was prescribed oral warfarin for 6 months. Treatment resulted in the complete disappearance of the PVT. This therapeutic strategy should be considered in the management of other cases of this rare, complex disease.
