Reference Curve for the Mean Uterine Artery Pulsatility Index in Singleton Pregnancies.
INTRODUCTION Doppler sonography of the uterine artery (UA) is done to monitor pregnancies, because the detected flow patterns are useful to draw inferences about possible disorders of trophoblast invasion. Increased resistance in the UA is associated with an increased risk of preeclampsia and/or intrauterine growth restriction (IUGR) and perinatal mortality. In the absence of standardized figur...
متن کاملUterine artery pulsatility index in hypertensive pregnancies: When does the index normalize in the puerperium?
OBJECTIVE To investigate whether the uterine artery pulsatility index (UtA PI) of hypertensive pregnancies is higher than that of normal pregnancies in the puerperium, as well as in the antepartum period. METHODS The UtA PI was measured in hypertensive (group 1) and normal pregnancies (group 2) during antepartum, immediate postpartum or late postpartum periods. Using the transvaginal approach...
متن کاملReference ranges for Doppler assessment of uterine artery resistance and pulsatility indices in dichorionic twin pregnancies.
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. METHODS This 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...
متن کاملUterine artery doppler pulsatility index at 11-14 weeks in ART pregnancies with egg-donation
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 ma...
متن کاملReference Ranges for Uterine Artery Pulsatility Index during the Menstrual Cycle: A Cross-Sectional Study
BACKGROUND Cyclic endometrial neoangiogenesis contributes to changes in local vascular patterns and is amenable to non-invasive assessment with Doppler sonography. We hypothesize that the uterine artery (UtA) impedance, measured by its pulsatility index (PI), exhibits a regular pattern during the normal menstrual cycle. Therefore, the main study objective was to derive normative new day-cycle-b...
