Prevention of Pre-eclampsia and SGA by Low-Dose Aspirin in Nulliparous Women With Abnormal First-trimester Uterine Artery Dopplers

The objective of this study is to test the efficacy of low-dose aspirin (160 mg/day), given bedtime and started early during pregnancy (≤ 15 +6 weeks of gestation) in nulliparous pregnant women selected as "high-risk" by the presence of a bilateral uterine artery notch and/or bilateral uterine artery PI ≥ 1.7 during the first trimester ultrasound scan (11-13+6 weeks), to prevent the occurrence of pre-eclampsia or small for gestational age at birth.
