We report 2 cases of Budd-Chiari syndrome that are due to complete membranous obstruction between the junction of the inferior vena cava and the right atrium. Both cases were treated successfully by King's bioptome breakthrough followed by balloon dilatation of the membrane. The patients showed remarkable symptomatic improvement and promising hemodynamic and angiographic results immediately after the procedure and 6 years later. We conclude that balloon angioplasty is a safe and effective method for treating this rare disease in selected cases.
