Results A total of pregnant Mexican women 65 PE women and 37 normotensive women were recruited in a cases and controls study. Second trimester placental changes associated with elevated maternal serum alpha-fetoprotein.

Cada gestante es un ser individual diferente, en algunos casos por diferentes factores, como por ejemplo, obesidad o edema de pared abdominal.

Alterations in any of the uterine artery parameters were interpreted as an abnormal result of this artery and consequently an abnormal general Doppler result was reported.

Raised maternal serum alpha-fetoprotein in the absence of fetal abnormality: Non-invasive measurement of human fetal circulation using ultrasound: Usefulness of a placental profile in high-risk pregnancies. Forbes K, Westwood M. Br J Obstet Gynaecol. For umbilical and middle cerebral vessels only their combination with another abnormal artery was considered to report an abnormal general Doppler result.

The uterine arteryvelocities and especially mean velocity showed better sensitivity, PPV, NPV, odds ratio and likelihood ratio than indexes as indicators of uterine hypoperfusion in pregnant women with intrauterine growth restriction. 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 of the Doppler US values in some populations [ 2627 ], and reports in doppldr the aim has been to get a spectral pattern of Doppler US to predict which pregnancies will evolve to PE [ 28 – 31 ].

The median of GW was 34 for the cases ranging from Placental bed spiral arteries in the hypertensive disorders of pregnancy. 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 dopler the fetus status evaluation [ 12 – 15 ].

Its routine use as a screening test is proposed, makinguse of the routine ultrasound scan at 20 weeks. Uterine artery doppler velocimetry during mid-second trimester to predict complications of pregnancy based on unilateral or bilateral abnormalities.

Results A total of Mexican women were recruited and sub-divided in two groups: Fetal umbilical artery flow velocity arterkas and placental resistance: Doppler blood flow in obstetrics. The prevalence of pre-eclampsia was 3.

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

Results in normal pregnancy. The pathophysiology of PE is based on the incapability of the trophoblast to invade properly the myometrium causing a limited remodeling of spiral arteries [ 7 ].

The aim of this study was to evaluate the uterine, umbilical, and the middle cerebral arteries using Doppler US parameters [resistance index RIpulsatility index PInotch Nsystolic peak SP and their combinations] in pregnant women, in order to make a global evaluation of hemodynamic repercussion caused by the established PE.
