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...

Background Fetal growth restriction is the second leading cause of perinatal morbidity and mortality. The incidence of intrauterine growth restriction (IUGR) is estimated to be approximately 5 percent in the general obstetric population. Abnormal uterine artery suggest a maternal cause for the growth restriction where as normal uterine artery Doppler studies suggest that a fetal cause. Use of u...

Background and Aim: Uterine placental bloodstream pressure can be measured by Doppler ultrasonography, which is a non-invasive technique. Uterine arteries velocimetry progressively decreases during the first and second trimesters in normal gestation due to trophoblastic invasion of musculoelastic membrane of uterine spiral arteries. The relationship between trophoblastic invasion and placental ...

Objective: To determine the usefulness of uterine artery Doppler in evaluation of third trimester high-risk pregnancies in prediction of adverse perinatal outcome. Methods: In this prospective study uterine artery Doppler parameters such as PI and early diastolic notch were recorded in a group of 60 high-risk pregnancies mainly consisting of pre-eclampsia and small for gestational age. Uterine ...

Abstract Background: Epidemiologic studies have shown the relationship of maternal hemoglobin level and abnormal findings in uterine Doppler sonography with pregnancy- related complications. In this study, we evaluated the relationship of uterine artery Doppler velocimetry findings and hemoglobin level with the outcomes of pregnancy in women with preeclampsi...

OBJECTIVE To compare umbilical and uterine artery Doppler in predicting outcome of pregnancies suspected of fetal growth restriction (FGR). DESIGN A prospective study included 353 singleton pregnancies complicated by an FGR fetus. SETTING University Hospital setting. SAMPLE Pregnancies suspected of FGR diagnosed by ultrasound fetal biometry during a 5-year period. MAIN OUTCOME MEASURE P...

Background and purpose: Abortion is considered recurrent when it spontaneously occurs at least three times. Recent studies suggest a correlation between uterine artery resistance and recurrent miscarriage (RM). There are few studies on the ovarian arteries. Therefore, this study evaluated the resistance of uterine and ovarian arteries in unexplained recurrent miscarriage and normal fertile w...

Introduction: Adequate levels of progesterone and efficient uteroplacental circulatory system are considered as two important factors in maintaining normal pregnancy. Conspicuously, increased vascular resistance in the uterine artery can lead to severe complications including threatened abortion by an impairment to the embryo’s blood supply. This study was conducted to determine whether vaginal...

OBJECTIVES To evaluate the predictive capacity of umbilical, cerebral and uterine artery Doppler in women admitted for preeclampsia (PE). METHODS 190 consecutive singleton pregnancies admitted with PE were included. Umbilical, cerebral and uterine artery Dopplers were performed. The association with adverse perinatal outcome was evaluated from 2 x 2 tables and multivariately by logistic regre...
