Gestational age weeks, median preeclampisa. A critical appraisal of the use of umbilical artery doppler ultrasound in high-risk pregnancies: Discussion Most of reports related to PE evaluation by Doppler US have been focused on pteeclampsia 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 of the Doppler US values in some populations [ 2627 ], and reports in which the aim has been to get a spectral pattern of Doppler US to predict which pregnancies will evolve to PE [ 28 – 31 ].

Doppler ultrasound evaluation in preeclampsia

Quinta El Sol Haemodynamic changes in the second half of pregnancy: EmPlasencia et al. General Doppler US result, as well as N from uterine vessel, RI from umbilical artery, and PI from utterinas and middle cerebral arteries in their individual form, may be considered as tools to determine hemodynamic repercussion caused by PE. All authors read and approved the final manuscript.

Umbilical artery doppler velocimetry—an update. 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 xrterias. It could be because the reference values considered in previous studies consisted of standardized measures for each population, and the abnormality limits of these values may differ between populations [ 40 ].
