Added Value in Low-Risk Pregnancies of Longitudinal Changes in Uterine Doppler and Circulating Angiogenic Factors during the Third Trimester in Predicting Term Preeclampsia.

Introduction: The objective of this study was to assess the relationship between longitudinal changes in the uterine Doppler velocimetry and the maternal profile of angiogenic factors in the third trimester and to assess their ability to predict term preeclampsia (PE).

Methods: A cohort of low-risk pregnant women was scheduled for a uterine Doppler evaluation and measurement of the circulating levels of angiogenic factors at ∼30 and ∼36 weeks. The performance of both parameters and their change over time in predicting term PE was evaluated.
