Interstitial Laser Ablation of Feeding Vessels to a Large Placental Chorioangioma

Abstract

Background: Chorioangioma is a vascular neoplasm of the placenta with the potential to cause heart failure, hydrops, and even death.

Case: A 30-year-old patient was referred owing to a large placental chorioangioma and fetal hydrops at 28 weeks of gestation. The patient underwent ultrasound-guided interstitial laser ablation. Ten days later, fetal blood transfusion was performed and at 31 weeks of gestation, and the patient delivered a female infant by cesarean section. The newborn was discharged from the neonatal intensive care unit without any complication.

Conclusion: According to our case, large placental chorioangioma may have a favorable outcome with interstitial laser ablation and fetal transfusion.
