Limits of preeclampsia screening and prevention in a population of women after assisted reproductive technologies.

Pregnancies resulting from assisted reproductive technologies are associated with an increased risk of developing preeclampsia. Available data indicate that one of the risk factors is frozen embryo transfer in an artificial cycle. Assessment of the pulsatility index of the uterine artery along with maternal factors and serum biomarkers form the basis for preeclampsia screening in the 1st trimester. Current evidence suggests that the method of endometrial preparation for embryo transfer may influence uterine artery pulsatility index values, thereby affecting the estimation of preeclampsia risk.
