We report the successful treatment of a case of severe hepatic veno-occlusive disease (VOD) by combined treatment with exchange plasmapheresis and fibrinolysis with rt-PA. Very advanced alterations of hepatic vascular circulation, evaluated by Doppler sonography, reverted to normal after treatment. Severe VOD, defined by McDonald's criteria, produces a mortality of 98%. This case suggests that this new method of combined treatment might contribute to changing the usually bad prognosis of this clinical condition.
