Randomized controlled trial using low‐dose aspirin in the prevention of pre‐eclampsia in women with abnormal uterine artery Doppler at 23 weeks' gestation

Abstract

In pregnancies with impaired placentation, as demonstrated by increased impedance to flow in the uterine arteries, the daily administration of 150 mg aspirin after 23 weeks of gestation does not prevent the subsequent development of pre-eclampsia.
