OBJECTIVES To construct reference ranges of uterine artery Doppler parameters against gestation in twin pregnancies and to present charts of the pulsatility index (PI) and resistance index (RI) for clinical use. [] Key MethodThis was an observational study of the uterine circulation in 557 women with dichorionic twin pregnancies at 17-38 weeks' gestation. Uterine artery measurements were performed by color and pulsed Doppler imaging. The uterine artery PI and RI were calculated as a mean of both sides…
First trimester markers of preeclampsia in twins: maternal mean arterial pressure and uterine artery Doppler pulsatility index
This study aims to evaluate the distribution of mean arterial pressure (MAP) and uterine artery Doppler pulsatility index (PI) in first trimester twins with and without preeclampsia.
Prediction of pregnancy complications by second‐trimester uterine artery Doppler assessment in monochorionic twins
We aimed to investigate whether transabdominal uterine artery (UtA) pulsatility index (PI) differs between monochorionic (MC) diamniotic and dichorionic (DC) twins and is useful to predict pregnancy
Uterine artery Doppler evaluation in twin pregnancies at 11 + 0 to 13 + 6 weeks of gestation
To compare uterine artery pulsatility index (PI) obtained at 11 + 0 to 13 + 6 weeks of gestation in singleton and twin pregnancies and to evaluate changes in PI values of twin pregnancies developing
Uterine Artery Doppler Reference Ranges in a Twin Caucasian Population Followed Longitudinally From 17 to 37 Weeks Gestation Compared to That of Singletons
TLDR
The primary aim was to measure uterine artery indices in twin pregnancies of Polish Caucasian women and compare it with a previously published study by Geipel et al for DC twins (2011), and find differences in UtA indices in MC, DC twins, and singletons.
Second trimester uterine artery pulsatility index and chorionicity in twins
TLDR
Second trimester uterine artery pulsatility index measurements do not differ between chorionicity types and has no effect on twin pregnancy outcome in terms of fetal weight and birth weight.
Doppler Velocimetry of the Ophthalmic Artery Behavior in Twin Pregnancy
TLDR
It is concluded that there are no significant differences in ophthalmic artery behavior in twins and the same reference values established in singleton pregnancies can be applied for PI and PR indexes in the evaluation of twin pregnancies.
Predicting Obstetric Vasculopathies through Study of Diastolic Notch and other Indices of Resistance to Blood Flow in Uterine Artery
TLDR
The combination of a diastolic notch and an abnormal resistance index in both uterine arteries at 20 weeks gestation is more accurate indicator in predicting severe pregnancy complications and is clinically more useful in predicting pre-eclampsia than the two conventional indices.
First-Trimester Uterine Artery Doppler Analysis in the Prediction of Later Pregnancy Complications
TLDR
Overall, first-trimester Doppler interrogation of the uterine artery performs better in the prediction of early-onset than late-ONSet preeclampsia.

TLDR
To construct gestational age (GA)‐based reference ranges for the uterine artery (UtA) mean pulsatility index (PI) at 11–41 weeks of pregnancy, the mean pulsatile index was calculated by subtracting the age of the mother and the child from the patient to construct reference ranges.
