Uterine artery doppler pulsatility index at 11-14 weeks in ART pregnancies with egg-donation
ثبت نشده
چکیده
Objective Uterine artery Doppler studies with measurement of pulsatility index (UtPI) represent recognized predictors of placental insufficiency and preeclampsia. Mode of conception (MC) has not been shown to modify the PI of uterine arteries; however we are not aware of studies investigating egg donations (ED). We hypothesize that perfusion of uterine arteries evaluated with Doppler studies may be different in pregnancies conceived after ED and we tested this hypothesis in an exploratory case-control trial.

Uterine artery Doppler at 11-14 weeks of gestation in chromosomally abnormal fetuses.
OBJECTIVE To determine whether the major chromosomal abnormalities are associated with impaired placentation in the first trimester of pregnancy. METHODS This was a prospective study of 692 singleton pregnancies undergoing fetal karyotyping at 11-14 weeks of gestation. Uterine artery Doppler was carried out and the mean pulsatility index was calculated just before chorionic villus sampling. ...

Background Preeclampsia is a specific pregnancy syndrome. Early diagnosis and proper administration of preeclampsia can lead to improved maternal and neonatal outcome. We aimed to investigate the uterine artery Doppler ultrasound in predicting the preeclampsia in women with a high-risk pregnancy. Materials and Methods This analytic study was conducted on 160 primigravida women with gestational...
متن کاملUterine artery Doppler study in second trimester of pregnancy
INTRODUCTION The uterine artery Doppler has potentials for screening for complications of impaired placentation. This study examines the indices of uterine artery impedance at 22-23 weeks gestation and their relationship with maternal age and parity. METHODS Uterine artery colour imaging and pulsed wave Doppler ultrasound was conducted between 22nd and 23rd weeks in 430 pregnancies. The pregn...
