We experienced a case with fetal hydrops, polyhydramnios, and a well-defined oval anechoic lesion of approximately 9 cm in size, without blood flow at 26 weeks' gestation. As increased middle cerebral artery peak systolic velocity, the fetal hydrops was caused by a placental tumor such as a chorioangioma; however, the tumor was atypical. Fetal blood hemoglobin was 8.3 g/dl on percutaneous umbilical cord blood sampling. After erythrocytes transfusion to the fetus, the mother normally delivered at 38 weeks' gestation. The placental tumor was histologically diagnosed as a necrotic chorioangioma. Obstetricians should note such atypical chorioangiomas when differential diagnosis of placental tumors.

01:14Fetal 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...
01:07Development of Blood Vessels
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
