Submission of 3 images demonstrating color flow mapping and waveforms of the uterine artery at weeks. Br J Obstet Gynaecol. Uteroplacental arterial changes related to interstitial trophoblast migration in early human pregnancy.
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.

Comparison dpopler placental growth factor and fetal flow doppler ultrasonography to identify fetal adverse outcomes in women with hypertensive disorders of pregnancy: Cada gestante es un ser individual diferente, en algunos casos por diferentes factores, como por ejemplo, obesidad o edema de pared abdominal.

Decreases adterias individual RI or PI values, as well as their combination in the middle cerebral artery were considered as an abnormal artery result. Its routine use doppled a screening test is proposed, makinguse of the routine ultrasound scan at 20 weeks. Acta Colombiana de Cuidado Intensivo.
Doppler ultrasound evaluation in preeclampsia
The authors declare that they have no competing interests. The general Doppler result had the most representative values with specificity and PPV of Considering the abnormal middle cerebral artery results, 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.
Longitudinal evaluation of uteroplacental and umbilical blood flow changes in normal early pregnancy. Services on Demand Journal. Uterine artery Doppler velocimetry in relation to trophoblast migration into the myometrium of preecclampsia placental bed. Estudo recente de Coleman et al. 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 ].
Doppler ultrasound of the uterine arteries: Even though PE prediction was not the aim of this study, the capability of Doppler assessment to classify correctly the study groups was determined using individual parameters and their combinations.
Uterine Artery Doppler in Screening for Preeclampsia and Fetal Growth Restriction.
A comparison of Doppler ultrasound waveform indices in the umbilical artery. Most of the patients were not on any treatment at the time of examination, the patients from the cases group with treatment, had been on it for less than 2 days. The latter has been considered a useful method for prediction of PE and adverse pregnancy outcome [ 89 ].
Trophoblastic invasion of human decidua from weeks of pregnancy. In general, individual or combined measurements showed high specificity and PPV, conversely to the low sensitivity and NPV.
