[Giant chorioangioma of the placenta]
Abstract:
The paper describes a case of giant (123 x 109 x 70-mm) placental chorioangioma that is a capillary hemangioma in structure, which led to significantly impaired placental-fetal blood flow to give rise to non-immune hydrops and right heart failure in the fetus at 33 weeks' gestation; obvious polyhydramnios developed. This served as an indication for preterm one-stage cesarean delivery. A premature live girl was born with a weight of 2430 g, a height of 44 cm, Apgar score 6-7. Dynamic echographic monitoring makes it possible to record increased placental tumor sizes and fetal abnormalities and to make a timely decision on delivery, which promotes perinatal death prevention. At 11-month follow-up, the child's physical and mental developments were for age.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
