Fetal cardiovascular response to large placental chorioangiomas.
A large placental chorioangioma is a relatively rare condition, which in 50% of all cases will lead to maternal and fetal complications. Since chorioangiomas are often associated with significant arterio-venous shunting within the placenta, several fetal hemodynamic compensatory mechanisms are initiated. Ultrasound and color Doppler flow mapping are important for the prenatal diagnosis of chorioangiomas, as an early prenatal diagnosis is crucial to minimize the risks for fetal well-being. Close surveillance of pregnancy and pregnancy termination by cesarean section at the earliest signs of fetal cardiac decompensation are indicated to reduce fetal and neonatal complications. Novel intrauterine treatment options include intravascular transfusion, fetoscopic devascularization, microcoil embolization, and intravascular injection of absolute alcohol.
