Pulmonary veno-occlusive disease is refractory to medical treatment and is generally associated with a poor prognosis. Treatment with vasodilators, such as prostacyclin, of patients with PVOD is controversial because of concerns regarding hemodynamic deterioration. Although a preferential pulmonary vasodilatory effect of a specific phosphodiesterase-5 inhibitor, sildenafil, has recently been reported in patients with primary pulmonary hypertension, little information is available regarding the effect of sildenafil on patients with pulmonary veno-occlusive disease. In the present case, remarkable improvement of hemodynamics and of clinical course was produced by adjunctive use of oral sildenafil in association with intravenous high-dose epoprostenol. These findings suggest that sildenafil may be a therapeutic option in the medical treatment of pulmonary veno-occlusive disease.
