A resistência ao fluxo sanguíneo nas artérias umbilicais depende diretamente das condições da circulação útero-placentária. UtAs were examined by color and pulsed Doppler imaging, and the mean PI, as well as the presence or absence of a bilateral protodiastolic notch, were recorded. Polynomials were fitted by means of least-square regression to estimate the relationship between the mean UtA-PI and GA. Results: A total of 620 women were included. La arteria uterina, una de las ramas principales de la arteria iliaca interna (hipogástrica), entra en la base del ligamento ancho y va en dirección medial hacia el borde lateral del útero (14, 15).

Conclusion: According to the results, uterine artery Doppler ultrasonography had high negative predictive value for prediction of preeclampsia, abruption, and LBW. Therefore, absence of uterine artery notching in mid-trimester evaluation of high-risk pregnant women may predict better pregnancy outcome. We recommend Doppler ultrasonography for all high-risk pregnant women in second trimester for prediction of pregnancy outcome. Doppler imaging permits non-invasive evaluation of the uteroplacental circulation and is invaluable in the management of high risk pregnancies. A prospective quantitative experimental study tested the hypothesis that uterine artery (UA) spectral Doppler screening is able to identify patients at risk for developing pre-eclampsia.

Die Arteria uterina entspringt gewöhnlich aus dem vorderen Abschnitt der Arteria iliaca interna. Sie zieht horizontal zum Uterus und überkreuzt dabei ventral den Harnleiter. Objectives: To construct gestational age (GA)-based reference ranges for the uterine artery (UtA) mean pulsatility index (PI) at 11-41 weeks of pregnancy. Methods: A prospective cross-sectional observational study was carried out of 20 consecutive singleton pregnancies for each completed gestational week at 11-41 weeks. UtAs were examined by color and pulsed Doppler imaging, and the mean PI Doppler im II. Trimenon: A. uterina Screening: Risikoerfassung Das Risiko für eine klin.
