Twin pregnancy in a woman on long-term epoprostenol therapy for primary pulmonary hypertension. A case report.

BACKGROUND

Pregnancy associated with primary pulmonary hypertension is an uncommon observation, with maternal mortality > 50%. Experience treating this condition is limited. Past reports have emphasized the need for pregnancy termination. In the last few years there has been considerable interest in long-term intravenous use of epoprostenol (prostacyclin) in patients with primary pulmonary hypertension.

CASE: A woman with severe primary pulmonary hypertension who was on long-term epoprostenol therapy became pregnant with twins and was treated with high doses of epoprostenol and nitric oxide during delivery and the postpartum period. She was well six months later on continuous epoprostenol therapy. The one viable infant was alive and still hospitalized at this writing.

CONCLUSION

Epoprostenol therapy may be continued during pregnancy in patients with severe primary pulmonary hypertension for long-term pulmonary vasodilatation.
