Uterine Artery Pulsatility and Preeclampsia Risk in the First Trimester in Pregnancies Following Frozen Embryo Transfer
Accumulated evidence suggests that pregnancies following frozen embryo transfers in artificial cycles are associated with an increased risk of preeclampsia. Doppler ultrasonography of the uterine artery, along with maternal factors and serum biomarkers, is a crucial biomarker for first-trimester preeclampsia screening. It helps to identify “high-risk” patients.
