Abstract
IntroductionDoppler ultrasound is a very useful tool for measuring the flow of uterine arteries in the second trimester of pregnancy ObjectiveDetermining the relationship between maternal and perinatal adverse outcomes with those found in the Doppler of uterine arteries, and to identify in which risk groups this constitutes a better predictor of preeclampsia. MethodObservational, descriptive and prospective study, with a longitudinal cut. The sample consisted of 243 patients with risk factors, and divided into two groups according to the normal or pathological outcome of the Doppler at 20 and 26 weeks. Inferential statistics and parameter estimation test were performed. ResultsIn the pathological Doppler group there was increased incidence of retro-placental haematoma, preterm delivery, intrauterine growth restriction, and caesarean section, showing high specificity to rule out adverse events. The risk groups most benefited from uterine artery Doppler were autoimmune diseases and previous history of preeclampsia. ConclusionsThe Doppler of uterine arteries in the second trimester is a useful test in the prediction of preeclampsia and its maternal- perinatal complications in high-risk patients.
