Indomethacin therapy in the treatment of polyhydramnios due to placental chorioangioma.

A 26-year-old primigravida presented with acute polyhydramnios at 30 weeks gestation. Ultrasonography revealed a large placental chorioangioma with severe hydramnios. No anomalies were detected in the fetus. Preterm labor started with respiratory distress and indomethacin, 25 mg was given every 6 hours. The patient showed a good response with improvement of the hydramnios and respiratory symptoms. A normal infant with no neonatal complications was delivered 3 weeks later.
