Role of Antenatal Intervention and Pregnancy Outcome in Large Chorioangiomas

Successful expectant management of a giant chorioangioma

Giant chorioangiomas are benign placental tumours, which can have potential severe fetal consequences. Complications in pregnancy include polyhydramnios, fetal hydrops and growth restriction. Such pregnancies can carry a significant risk of poor perinatal outcome and require close monitoring. Therapeutic options include fetoscopic or interstitial vessel ablation, chemosclerosis and embolisation. Where there is no evidence of fetal compromise, such pregnancies can successfully be managed conservatively.
