First trimester prediction of ischemic placental disease.
Ischemic placental disease is characterized by one or more of the clinical manifestations of preeclampsia, fetal growth restriction, and/or placental abruption, resulting in indicated preterm delivery. Since over half of the indicated preterm deliveries are due to ischemic placental disease, accurate early prediction of the disease is of paramount importance in developing prevention strategies. This review article focuses on studies that have used the first trimester aneuploidy screening timing window to predict those patients who later develop ischemic placental disease. Emphasis was given to studies originating from the Fetal Medicine Foundation because of their uniformity in definitions and expertise of the personnel who performed the ultrasound screening exams.
