sFlt-1/PlGF Ratio at 24 Weeks Gestation in Twin Pregnancies as a Predictor of Preeclampsia or Fetal Growth Restriction.

Introduction: The objective was to elucidate if the sFlt-1/PlGF ratio at 24 weeks in twin pregnancies could be useful to select patients who subsequently develop diseases related to placental dysfunction, such as preeclampsia or fetal growth restriction (FGR).

Methods: This was a prospective study among all twin pregnancies followed up at a tertiary hospital. The sFlt-1/PlGF ratio was determined at 24 weeks.
