The role of color Doppler imaging of the uterine arteries at 20 weeks’ gestation in stratifying antenatal care. Br J Obstet Gynaecol, 92pp. Ultrasound Obstet Gynecol, 18pp. Uterine artery doppler flow and uteroplacental vascular pathology in normal pregnancies and pregnancies complicated by pre-eclampsia and small for gestational age fetuses.

Uterine Artery Doppler in Screening for Preeclampsia and Fetal Growth Restriction.

Mean gestational age for the IUGR and control groups were respectively Most of reports related to PE evaluation by Doppler US have been focused on the study of the uterine artery and its parameters [ 22 – 24 ]; there are descriptive trials about the hemodynamic changes during pregnancy [ 25 ], studies to determine the normality ranges uterinss the Doppler US values in some populations [ 2627 ], and arrterias in which the aim has been to get a spectral pattern of Doppler US to predict which pregnancies will evolve to PE [ 28 – 31 ].

Regional hemodynamic adaptation during the menstrual cycle. Although there are some studies including the umbilical artery as a relevant vessel in the PE evaluation, traditionally this artery is taken together with the middle cerebral artery in the fetus status evaluation [ 12 – 15 ].

Uterine Artery Doppler in Screening for Preeclampsia and Fetal Growth Restriction.

The authors declare that they have preeclamlsia competing interests. Uterine artery is the most studied vessel in the Doppler evaluation in PE, because it represents the maternal vascular condition, through the pulsatility and resistance index PI and RI respectively and the presence of early diastolic notch N [ 1011 ].

Agterias of 3 images demonstrating color flow mapping and waveforms of the uterine jterinas at weeks. Mechanotransduction of shear in the endothelium: Am J Obstet Gynecol. The examination included one uterine artery from the placental side or the mean if there was a symmetrical placenta, the umbilical artery, and one middle cerebral artery indistinct hemisphere [ 1819 ]. New doppler technique for assessing uteroplacental blood flow.

In Mexico, there are no reports about the Doppler US features for the three arteries in the PE evaluation; our results provide evidence about the possibilities to select better and specific measurements of each vessel in future early PE Doppler US screenings.

In this study we evaluate the uterine, umbilical, and the middle cerebral arteries using several Doppler US parameters RI, PI, N, SP and their combinations in order to make a global evaluation of hemodynamic repercussion caused by the established PE, in a cases and controls study.
