Abstract: In Colombia, patients classified as obstetric low risk have maternal or fetal adverse outcomes like pathologies associated with the alteration in placentation and Doppler of uterine arteries (DUA) is a useful method to predict complications derived from inadequate placentation. We decided to evaluate the prevalence alteration of DUA between week 20 and 24 of gestation in low-risk obstetric patients in Bucaramanga and its metropolitan area. We did a prospective cross-sectional study on this population and we report the result in 120 patients that were between 18 and 35 years old. There was an abnormality IP in 15.0% (18) of the patients (95% CI from 9.1% to 22.7%), of the IR in 25.0% (30) (95% CI from 17.3% to 33.7%) and presence of Notch in 10.8% (13) (95% CI from 5.9% to 17.8%). Of 18 (15.0%) patients who had impaired PI 2 had normal RI and the Notch was absent in 6. The three parameters were altered in 11 (9.2%) patients. That result was expected according to the selection criteria we used to define the obstetric low-risk population.
