Primary pulmonary hypertension treated with short-term epoprostenol infusion.

We describe the use of short-term epoprostenol in a 61-year-old man with primary pulmonary hypertension. The patient was on a ventilator because of respiratory distress. Continuous infusion of epoprostenol was started and it initially reduced the pulmonary artery pressure by 32%. Epoprostenol was tapered, and even after discontinuation, the pulmonary artery pressure was controlled. The ventilator was removed, and the patient remained well on home oxygen therapy 3 months after discharge.
