TREATMENT OF LARGE CHORIOANGIOMA OF THE PLACENTA BY FETOSCOPIC LASER COAGULATION OF BLOOD VESSELS

Lacental chorioangioma is the most common nontrophoblastic tumor of the placenta, occurring in 0.41-1.4 % of examined placentas by microscopy. About half of large chorioangiomas can cause fetal complications such as polyhydramnios, fetal anemia, intrauterine growth retardation, heart failure, fetal hydrops and intrauterine fetal death, complications such as hemolytic anemia, thrombocytopenia, disseminated intravascular coagulation, pregnancy-induced hypertension, maternal mirror syndrome, hemoglobinuria and postpartum bleeding. We performed fetoscopic laser coagulation of blood vessels of the large placental chorioangioma at 23 weeks, which prevented the development of fetal heart failure and other serious pregnancy complications.
