Uterine arteries Archives - Revista Brasileira de Ginecologia e Obstetrícia
Summary
Rev Bras Ginecol Obstet. 2018;40(5):287-293
To perform a comprehensive review of the current evidence on the role of uterine artery Doppler, isolated or in combination with other markers, in screening for preeclampsia (PE) and fetal growth restriction (FGR) in the general population. The review included recently published large cohort studies and randomized trials.
A search of the literature was conducted usingMedline, PubMed, MeSH and ScienceDirect. Combinations of the search terms “preeclampsia,” “screening,” “prediction,” “Doppler,” “Doppler velocimetry,” “fetal growth restriction,” “small for gestational age” and “uterine artery” were used. Articles in English (excluding reviews) reporting the use of uterine artery Doppler in screening for PE and FGR were included.
Thirty articles were included. As a single predictor, uterine artery Doppler detects less than 50% of the cases of PE and no more than 40% of the pregnancies affected by FGR. Logistic regression-based models that allow calculation of individual risk based on the combination of multiple markers, in turn, is able to detect ~ 75% of the cases of preterm PE and 55% of the pregnancies resulting in small for gestational age infants.
The use of uterine artery Doppler as a single predictive test for PE and FGR has poor accuracy. However, its combined use in predictive models is promising, being more accurate in detecting preterm PE than FGR.

OBJECTIVE: to observe if there is any alteration in the Dopplervelocimetry of the uterine arteries of nursing and not nursing women after the insertion of the copper T 380 intrauterine device (IUD). METHODS: prospective, analytical, self-paired clinical assay, with 100 patients in whom we evaluated the color doppler flow: resistance index (RI), pulsative index (PI) and systole/diastole (SD) ratio. Nursing and not nursing women were assessed before IUD insertion as well as 30 days (one cycle) and 90 days (three cycles) after the insertion. RESULTS: the values obtained in the uterine arteries before insertion were: RI: 0.9, PI: 2.4, and SD ratio: 10.0. The values 30 days after insertion were: RI: 0.9, PI: 2.5 and SD ratio: 10.7. After three cycles we found a value of 0.9 for RI, 2.5 for PI and 10.7 for SD ratio. The comparison of the results before and after the IUD insertion showed a p value of 0.51 for RI, of 0.37 for PI and of 0.51 for SD ratio, demonstrating that after the insertion of the IUD, there were no significant changes in Dopplervelocimetry. Also, there were not significant differences between nursing and not nursing women, concerning these parameters. CONCLUSIONS: the use of copper T 380 IUD has no effect on the Doppler indices of the uterine arteries of both nursing and not nursing women.
