Pulmonary veno-occlusive disease (PVOD) or pulmonary capillary hemangiomatosis (PCH) is a rare subtype of pulmonary hypertension with dismal prognosis. Limited data are available on the efficacy and safety of orally administered pulmonary vasodilators for PVOD/PCH. Whether and how systemic sclerosis (SSc) affects the clinical outcomes of PVOD/PCH is also unknown. This study aimed to determine the clinical and hemodynamic efficacy and safety of oral pulmonary vasodilators for PVOD/PCH and clarify the possible effects of SSc on the clinical presentation of PVOD/PCH. We retrospectively analyzed the clinical data of 15 patients with PVOD/PCH treated with oral pulmonary vasodilators in our department since 2001. Six of them had SSc. Oral pulmonary vasodilators were administered either as single agents (n = 10) or in combination (n = 5). Treatment improved the functional class of five patients, and pulmonary arterial pressure and pulmonary vascular resistance decreased by 10 ± 12 mmHg and 36 ± 19%, respectively (p < 0.05 for both, n = 13), whereas pulmonary edema developed in three patients. The mean survival was 3.9 years, and the 1- and 3-year survival rates were 93% and 65%, respectively. The clinical presentation, including survival, was similar between patients with and without SSc. In our PVOD/PCH cohort, oral pulmonary vasodilators caused pulmonary edema in 20% of patients, but more than 80% of patients experienced significant pulmonary vasodilatory effects, and the overall prognosis was better than that previously reported. SSc does not adversely affect the clinical outcomes of PVOD/PCH.
