Screening with a uterine Doppler in low risk pregnant women followed by low dose aspirin in women with abnormal results: a multicenter randomised controlled trial

Abstract

There is no justification for screening with uterine artery Doppler in a low risk population, even if abnormal results are followed by aspirin treatment and increased prenatal surveillance. Future studies must assess predictive tests that can be performed early in pregnancy and can identify populations at very high risk of pre-eclampsia and intrauterine growth restriction. Only when all of these conditions are fulfilled, aspirin or other treatments may prove its efficacy.
