Background: Placental chorioangioma is a relatively rare malformation with potential to cause fetal hydrops and even death. We describe ultrasound-guided interstitial laser as a modality for treating chorioangiomas of the placenta.
Case: The patient presented at midgestation with placental chorioangioma resulting in fetal cardiomegaly. Interstitial laser was performed under local anesthesia on two occasions and resulted in arrest of flow through the tumor feeder vessel.
Conclusion: Interstitial laser therapy in a patient with placental chorioangioma resulted in a successful outcome.
