Placental pathology lesions: International Society for Ultrasound in Obstetrics and Gynecology vs Society for Maternal-Fetal Medicine fetal growth restriction definitions.

Research on the definition of fetal growth restriction (fetal growth restriction) has focused on predicting adverse perinatal outcomes.

To compare the diagnostic performance of the fetal growth restriction definitions established by the International Society for Ultrasound in Obstetrics and Gynecology (International Society for Ultrasound in Obstetrics and Gynecology) and the Society for Maternal-Fetal Medicine (Society for Maternal-Fetal Medicine) to predict placental histopathological findings associated with placental insufficiency and a composite adverse neonatal outcome (adverse neonatal outcome).
