[Membranous obstruction of the inferior vena cava].

A case of idiopathic membranous obstruction of the inferior vena cava (MOVC) is reported. Varicose veins of both lower limbs associated with dermatitis and venous ulceration were the presenting symptoms. Diagnosis was made by cavography after phlebography of both legs had revealed a normal deep system. Ultrasonography demonstrated a 4 mm thick membrane in the inferior vena cava just above the level of the hepatic veins. Stripping of the greater saphenous vein and ligation of incompetent perforating veins was performed to partially correct the venous insufficiency of the most affected limb. The patient refused further treatment of the MOVC. Concise review of the literature. Up to date therapeutic possibilities are discussed.
