Transformation of inferior vena caval thrombosis to membranous obstruction in a patient with the lupus anticoagulant.
A 24-yr-old woman with hemolytic anemia developed multiple thrombosis of the hepatic vein and inferior vena cava. She was found to have circulating lupus anticoagulant that could have been causally related to the thrombosis and hence the Budd-Chiari syndrome. On her first admission to the hospital vena cava and hepatic vein catheterizations revealed partial thrombotic occlusion of the cava at the level of the diaphragm, which was subsequently transformed into complete membranous obstruction. The right hepatic vein, which was patent on the first admission, was also completely occluded. These observations support the theory that membranous obstruction of the inferior vena cava is a sequela to inferior vena caval thrombosis rather than a congenital anomaly.
