title: Arteriovenous fistulas of the placenta in a singleton fetus with large atrial septal defect and anomalous connection of the umbilical veins.
abstract: Arteriovenous fistulas of the placenta rarely occur in singleton pregnancies. This report describes the fetal and neonatal hemodynamic pattern in a singleton gestation in which multiple placental artery-to-vein anastomoses were associated with a large atrial septal defect and a single umbilical artery with an anomalous connection of the persistent right and left umbilical veins. Possible links between the extracardiac vascular malformation and the congenital heart defect are discussed.
