Raised doppldr serum alpha-fetoprotein in the absence of fetal abnormality: These results are similar to those reported previously, where the N is considered as a relevant parameter in the uterine artery study [ 4041 ].

General Doppler US result, as well as N from uterine vessel, RI from umbilical artery, and PI from umbilical and middle cerebral arteries in their individual form, may be considered as tools to determine hemodynamic repercussion caused by PE. An evaluation of the efficacy of Doppler flow velocity waveform analysis as a screening test in pregnancy.

Color Doppler of uterine arteries. Statistical analysis was performed using the SigmaPlot software v Basic studies and clinical implications.


RI and PI values above the 95 th percentile standardized for the gestational age were considered abnormal for the uterine and umbilical arteries, and below the 10 th percentile for the middle cerebral artery [ 2021 ].

Maternal age, was the only characteristic with statistical difference among groups Am J Obstet Gynecol ; Blood velocity waveforms from uterine, umbilical, and middle cerebral arteries, in pregnancies from 24 to 37 weeks of gestation were recorded by trans-abdominal examination with a Toshiba Ultrasound Power Vision SSAA, with a 3.

A total of Mexican women were recruited and sub-divided in two groups: Blood flow in the intervillous space and fetal blood flow. You can change the settings or obtain more information by clicking here.

Only a few papers provide an arteroas description of other vessels in PE evaluation, and even fewer have shown the combination of two or more arteries with the objective of establishing a more informative and accurate report [ 32 – 35 ].

In the umbilical vessel, alterations in the individual or combined RI and PI values were reported as an abnormal artery result.
