QUINTERO, Janeth et al. Velocimetría Doppler de la arteria uterina como factor de predicción de preeclampsia y crecimiento fetal restringido. Rev Obstet Ginecol Venez [online]. 2002, vol.62, n.3, pp.153-159. ISSN 0048-7732.

Objective: To determine the usefulness of uterine artery Doppler ultrasound in the prediction of pre eclampsia or fetal growth restriction, in low risk women. Method: Uterine arteries Doppler screening was performed in 100 pregnant women, since 26 week. A systolic/diastolic index was calculated from each uterine artery and the presence or absence of a notch was determined. Systolic/diastolic index > 2.7 or notch was defined as abnormal. All patients were followed to birth and main outcome measures were preeclampsia and fetal growth restriction. Setting: High risk obstetric, prenatal service at "Concepcion Palacios" Maternity Hospital. Results: Eight women (8%) developed preeclampsia and eight women (8%) developed fetal growth restriction. The sensitivity and specificity of bilateral notch for preeclampsia and fetal growth restriction was: 62,5%, 92,2% and 85,7%, 93,4% respectively. The sensitivity and specificity of abnormal systolic/diastolic index for preeclampsia and fetal growth restriction was: 37,5%, 94,5% and 87,5%, 98,9% respectively. Conclusion: uterine artery Doppler waveform analysis is useful in the prediction of preeclampsia and fetal growth restriction in low risk women.
