Objective: To sonographically evaluate the dominant fibroid nodule vascularity and flow velocity pattern of perifibroid and intrafibroid arteries. Methods: We recruited 140 women with uterine fibroids. Their uteri were scanned to determine the vascularity of fibroid nodules and the Doppler indices of the fibroid arteries. Results: The median volume of the dominant leiomyoma nodule was 133 cm3 (range=1.5-2,575 cm3 ). Eighty-three subjects (59...

OBJECTIVES: To evaluate different strategies for the prediction of late preeclampsia. METHODS: A retrospective study was undertaken. A predictive model including maternal parameters (maternal age, maternal BMI, maternal history of preeclampsia or intrauterine growth restriction (PE/IUGR) or maternal chronic disease, and maternal arterial pressure) and mean pulsatility index (PI) of uterine Doppler was created. It was evaluated as an independent model in each trimester, considering 11-13...

OBJECTIVES: Endocan plays a role in the development of vascular tissue in health and disease and is an indicator of endothelial cells activation and angiogenesis. Therefore, this study aimed to investigate the relationship between maternal endocan serum level and intrauterine growth restriction (IUGR) as well as ultrasound Doppler flow measurements indicating placental insufficiency. METHODS: This study included a group of women with IUGR (n = 37) and a group of healthy pregnant women (controls, n = 37)...

OBJECTIVE: To identify key factors implicated in adverse perinatal outcome in monochorionic twin pregnancies complicated by selective fetal growth restriction. METHODS: This is a retrospective cohort study conducted in a single tertiary referral centre included all monochorionic diamniotic (MCDA) twin pregnancies complicated by selective fetal growth restriction (sFGR). The presence of co-existing twin to twin transfusion syndrome (TTTS) was noted. Fetal biometry and Doppler indices, including the umbilical artery (UA) and ductus venosus (DV), were recorded at the time of diagnosis...

Purpose: The aim of the study was to evaluate the effect of clomiphene citrate on uterine artery blood flow using pulsed Doppler and endometrial and subendometrial micro vascularization using 3D power Doppler in unexplained infertility. Patients and methods: In a prospective observational study at a university teaching hospital, the mid-luteal (peri-implantation) endometrial thickness and volume, uterine artery pulsatility index (PI) and resistance index (RI), endometrial and subendometrial vascularization index (VI), flow index (FI), and vascularization flow index (VFI), and serum estradiol and progesterone levels were compared between natural and clomiphene citrate stimulated cycles in the same group of 50 patients with unexplained infertility...

OBJECTIVES: To assess whether in a cohort of patients with small for gestational age (SGA) foetuses with estimated fetal weight ≤10th percentile, maternal hemodynamics, fetal biometry and Dopplers at presentation, can predict the subsequent development of abnormal fetal Dopplers or delivery with birthweight <3rd percentile. METHODS: The study population comprised of 86 singleton pregnancies with SGA fetuses presenting at a median gestational age of 32 (range 26-35) weeks...

AIM: To develop a first-trimester or combined first- and second-trimester screening algorithm for the prediction of small-for-gestational age (SGA) and late growth-restriction (FGR). METHODS: This was a retrospective study of pregnant women with singleton pregnancy, who attended routine first- second- and third-trimester ultrasound scan. Late FGR was defined, at ≥32 weeks in the absence of congenital anomalies as, either (a) estimated fetal weight (EFW) or birthweight (BW) <3rd centile , OR (b) EFW<10th centile and either uterine artery mean PI >95th centile or cerebroplacental ratio (CPR) <5th centile...

The effect of Shoutai pill on endometrial receptivity was analyzed. A total of 160 patients with spontaneous abortion were enrolled in this study. They were treated in the Fifth People's Hospital of Jinan (Shandong, China) from February 2014 to June 2016. The following treatment regimen was performed for the patients: after menstruation, Shoutai pill was taken as continuous medication for more than 5 menstrual cycles, the pill was taken 20 days per month, medication was stopped during menstruation, and contraceptive measures were taken during this period...

The objective of this study was to assess the uterine blood flow following estradiol benzoate administration in Holstein-Friesian dairy cows by trans-rectal color Doppler ultrasonography. Six healthy lactating Holstein-Friesian cows were examined daily for 10 days starting at 4 weeks postpartum. All the cows, which were clinically healthy based on vaginal mucus scoring and endometrial cytology, were examined by trans-rectal Doppler ultrasonography to measure pulsatility index (PI), resistance index (RI), time average maximum velocity (TAMAX), blood flow volume (BFV) and diameter in the uterine arteries ipsilateral and contralateral to the previously pregnant uterine horn...

Pain relief of two different oral contraceptive pills (OCPs) in severe primary dysmenorrhoea (PD) was compared. Sixty-six nulliparous patients with severe PD requiring contraception were evaluated. Group 1 comprised 33 healthy controls. Patients with severe PD were divided into two groups. Patients in Group 2 were administered oestradiol valerate/dienogest and patients in Group 3 were administered ethinylestradiol/drospirenone. Doppler indices of both uterine arteries (left and right) including systolic/diastolicrates (S/D), pulsatility index (PI) and resistance index (RI) were measured, and a visual analogue scale (VAS) was applied to patients before treatment...

The primary aim of this study is to determine the value of using a combination of serum histidine-rich glycoprotein (HRG) level and uterine artery pulsatility index (PI) in pregnant women at 11-13+6 weeks' gestation to predict preeclampsia. The secondary aim is to determine the association between other pregnancy complications with the use of these combined tests. Transabdominal uterine artery PI and serum HRG level were measured at the time of first-trimester aneuploidy screening at 11-13+6 weeks' gestation in 327 pregnant women...

A greater understanding of the uterine artery's (UtA) biology is essential to the increase in female reproductive abilities. The UtA flow velocity waveform, blood flow volume (BFV), pulsatility and resistance indices (PI and RI), blood flow velocities, dynamics of the dominant follicle (DF), and estradiol (E2) and progesterone (P4) levels in an induced ovulatory cycle were evaluated in Thai native cattle. Twenty cows were induced with synchronized ovulation through a P4-releasing device, from Day -9 to Day -4, concurrent with the administration of two doses of a gonadotropin-releasing hormone on Day -9 and Day -1, and two doses of prostaglandin F2α on Day -4 and 8 h later...

Introduction: Postpartum haemorrhage (PPH) accounts for a high proportion of maternal mortality and morbidity throughout the world. A uterine compression belt which has been developed recently represents a very low tech, low cost solution in managing postpartum haemorrhage. Objectives: To evaluate the blood flow changes in pelvic vessels following application of the postpartum haemorrhage compression belt (Laerdal Global Health, Stavanger, Norway). Methods: The sample included healthy postpartum women within 6 hours of vaginal delivery...

INTRODUCTION: We evaluated the utility of placental volume and three-dimensional (3D) vascular flow indices to predict early and late preeclampsia. MATERIAL AND METHODS: In 1,004 pregnancies attending routine care, we recorded first-trimester screening program for aneuploidy (FTSA) parameter and measured uterine artery pulsatility index (uterine-a PI). Placental volume and vascular flow indices were obtained using 3D power Doppler and VOCAL techniques. RESULTS: Placental volume was lower and uterine-a PI was higher in both early and late preeclampsia groups versus nonaffected pregnancies...

Background: Recurrent spontaneous abortion has high incidence rate. The etiology is unknown in 30-40%. However high uterine artery resistance is accounted as one of the recurrent abortion reasons. Objective: The objective of the current study was to determine the impacts of vitamin E and aspirin on the uterine artery blood flow in women having recurrent abortions due to impaired uterine blood flow. Materials and Methods: This randomized clinical trial was conducted on 99 women having uterine pulsatility index (PI) more than 2...
