Ultrasound Obstet Gynecol ; 7: New doppler technique for assessing uteroplacental blood flow. The abnormality in the wave morphology was considered as the presence of a protodiastolic N after the 24 GW in the uterine artery [ 20 ]. The utility of uterine artery doppler velocimetry in prediction of preeclampsia in a low-risk population.

Duvekot J, Peeters I. Between [uly and April Doppler ultrasound of the uterine arteries was performed in pregnant women participating in the study and uterine arteries indexes and velocities were calculated; media were compared and RCIU diagnosis validity tests were performed.


Doppler ultrasound of the uterine arteries: 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. Br J Obstet Gynaecol. Ultrasound Obstet Gynecol, 16pp.

For umbilical and middle cerebral vessels only their combination with another abnormal artery was considered to report an abnormal general Doppler result. How to cite this article.

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 ]. 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 velocimetry of the uterine arteries in nulliparous women. Maternal preeclampsia and neonatal outcomes. 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.
