The utility of umbilical artery doppler in preterm premature rupture of membranes
… studies have shown some interest in the use of umbilical artery Doppler to predict latency as well as chorioamnionitis. This study aims to evaluate the ability of umbilical artery Doppler to predict latency period and correlate with the occurrence of chorioamnionitis. A retrospective chart …

The investigation of the calcium antagonist nifedipine on fetal umbilical artery Doppler waveforms
… on the Doppler flow velocity waveform of the umbilical artery. The thesis is divided into two parts. The first section is a literature review of the three main aspects of the thesis namely: 1. The uteroplacental circulation in humans and the pathophysiology related to this circulation in …

Umbilical artery Doppler velocimetry in predicting the perinatal outcomes in small for gestational age infants
… study is to evaluate the effectiveness of the umbilical artery Doppler velocimetry in predicting perinatal outcome of small for gestational age (SGA) infants. MATERIALS AND METHODS: During from Sep. 1995 to Feb. 2006, we retrospectively studied 422 singleton pregnancies with a diagnosis of SGA …

An assessment of the role of Doppler ultrasound velocity waveform analysis of the umbilical artery in the diagnosis of fetal distress in labour
… velocity waveform analysis of the fetal umbilical arteries in the diagnosis of fetal distress in labour is made from a review of the literature and clinical study. Study objectives: 1) To determine the value of screening with Doppler ultrasound in high-risk labours in the prediction of …

Investigating thyroid hormone transport and regulation in chorionic somatomammotropin RNAi models of intrauterine growth restricted pregnancies
… model of IUGR pregnancies. Uterine vein, uterine artery, umbilical vein, and umbilical artery serum was collected via catheterization, and maternal and fetal tissue was harvested near term (~135 dGA) from growth restricted CSH RNAi pregnancies (n=4) and control pregnancies (n=4). TTR protein …

Development in children born very preterm after intrauterine growth restriction with abnormal fetal blood flow
… growth restriction (IUGR) with abnormal umbilical artery blood flow in the second trimester represents a clinical dilemma. So far, no evidence based management protocols are available adressing when to deliver these fetuses. The high risk of hypoxia and fetal death has to be balanced …

Acute Fetal Behavioral Response to Prenatal Yoga: A Single Blinded, Randomized Controlled Trial
… and post intervention testing which consisted of umbilical and uterine artery Doppler ultrasound, non-stress testing, a biophysical profile, maternal blood pressure and maternal heart rate. A board-certified Maternal-Fetal Medicine specialist, at a different tertiary center, interpreted all …

Maternal and Umbilical Plasma Lipids Obtained During Elective Cesarean Section as Predictors of Macrosomia in Diabetic Pregnancy
… diabetic women with macrosomic babies. Radial artery, uterine vein, umbilical vein, and umbilical artery blood samples were analyzed in the fasting state for lipoprotein composition. Diabetic and diabetic-macrosomic infants had greater birth weight and skinfold measurements but not greater …

Umbilical arterial flow analysis to determine an index of placental impedance
Umbilical flow velocity waveforms (FVW' s) can be measured non-invasively using Doppler ultrasound. Changes in the FVW's occur long before the warning signs from other conventional monitoring methods. Correct interpretation of the changes in the FVW has the potential of providing the clinician with …

The impact of placental SLC2A3 (GLUT-3) RNA interference on fetal growth and physiology at mid-gestation in sheep
… the SLC2A3 RNAi pregnancies had decreased umbilical vein (p ≤ 0.05) and umbilical artery (p ≤ 0.05) glucose concentrations, as well as reduced umbilical artery insulin (p ≤ 0.10). Additionally, apparent attempts at compensation for SLC2A3-deficiency, by increasing SLC2A1, CSH, and IGF-2, …

Universal ultrasound screening in the third trimester
… age (LGA), (iii) high resistance pattern of umbilical artery Doppler flow velocimetry, (iv) low cerebro-placental ratio (CPR), (v) severe oligohydramnios, (vi) borderline oligohydramnios. I found that there was an on-going Cochrane Diagnostic Test Accuracy review for SGA, hence I focused on …

The effect of introducing Basic Antenatal Care Plus and Umbiflow on antenatal care and perinatal mortality
… viz. continuous wave Doppler ultrasound of the umbilical artery (CWDU-UmA) at a primary care level to detect placental insufficiency. (CWMU-UmA assesses the fetal blood flow to the placenta, and this has been shown to correlate very closely with placental function). Method: There were two major …

Intrauterine effects of maternal weight dynamics
… through the physiological drop in uterine and umbilical artery resistance throughout gestation. Obese women had a significantly smaller drop in uterine artery resistance between 20- and 36-weeks’ gestation, compared to normal weight women (change -21.3% [95% confidence interval -18.3, -24.3] …
