Abstract

Large placental chorioangiomas are rare complications in pregnancy. We present a case of a placental chorioangioma, complicated by polyhydramnios, in which obliteration of its blood supply using diode laser coagulation at 25 weeks of gestation was followed by an uneventful pregnancy and delivery of a healthy baby with a normal follow-up at the age of 9 months. Laser coagulation of the feeding vessels seems to be an effective treatment for chorioangiomas when the blood supply is superficial and the feeding vessels are small in diameter.
