OBJECTIVE We examined intraplacental color Doppler flow patterns and spectral Doppler flow velocity waveforms of villous arteries in pregnancies with intrauterine growth retardation. STUDY DESIGN A total of 192 uncomplicated pregnancies and 29 pregnancies with intrauterine growth retardation between 26 and 41 weeks' gestation were examined in this cross-sectional study. Intraplacental color D...

OBJECTIVE To relate Doppler velocimetry findings in fetoplacental and uteroplacental circulation to placental histomorphology. MATERIAL AND METHODS In 14 uncomplicated and 31 high-risk pregnancies Doppler velocimetry was performed in umbilical artery and vein, and in maternal uterine veins and arteries during the second half of gestation. Histopathology of the placentas was examined, especial...

Introduction: The incidence of intrauterine growth restriction is approximately 10%. The management depends upon diagnosis, follow up and timely delivery of the fetus. Material & Methods: Prospective cohort study was conducted at a zonal hospital from Oct 2014 to Aug 2016 on 60 women with clinical suspicion of FGR. After confirming FGR with ultrasound, these patients were followed with umbilica...

This review aims to provide the reader with an update on the present and potential clinical applications in Doppler ultrasound in perinatal medicine. Umbilical artery Doppler plays an important role in the management of intrauterine growth restriction (IUGR) and pre-eclampsia and aids in twin-to-twin transfusion syndrome management while notching in the waveform is a predictor of umbilical cord...

OBJECTIVES To evaluate placental volume and vascular indices in pregnancies with severe fetal growth restriction and determine their correlations to normal reference ranges and Doppler velocimetry results of uterine and umbilical arteries. METHODS Twenty-seven fetuses with estimated weights below the 3rd percentile for gestational age were evaluated. Placental volume and vascular indices, inc...

Background: True knot of the umbilical cord is an uncommon finding, which is difficult to diagnose antenatally. The appropriate management of patients with a sonographically identified true knot is yet to be determined. Case: We present a twin pregnancy, in which antenatal diagnosis of a true knot of the umbilical cord was made at 33 weeks’ gestation. Fetal Doppler examination showed an absence...

BACKGROUND Fetal growth restriction (FGR) is a condition with heterogeneous pathophysiology which characterized by fetal weight less than the tenth percentile for gestational age. Several factors have impact on maternal, placental and fetal due to growth restriction. OBJECTIVE The aim of this study was to investigate the relationship between levels of leptin in the cord, and serum leptin of m...

OBJECTIVE The purpose of this study was to evaluate Doppler flow velocity changes in cerebral vessels of monochorionic twins with twin-twin transfusion syndrome (TTTS). METHODS Repeated Doppler umbilical and cerebral blood flow studies were performed in 7 twin pairs with TTTS. Eight monochorionic twin pairs and 11 dichorionic twin pairs served as control groups. The following Doppler paramete...

Objective: To evaluate the screening efficiency of ultrasound and Doppler measurements in the prediction of fetal anemia in alloimmunized pregnancies. Materials and Method: In a prospective study, 24 nonhydropic fetuses with red blood cell alloimmunization were evaluated with ultrasound and Doppler imaging. Middle cerebral artery peak systolic velocity, intrahepatic umbilical venous maximum vel...

OBJECTIVE To evaluate the usefulness of Color Doppler flowmetry in the prediction of intrauterine growth restriction (IUGR) in high-risk pregnancies. MATERIALS AND METHOD A total of 62 high-risk pregnant women underwent Color Doppler flowmetric umbilical artery pulsatility index (PI), resistive index (RI) and systolic/diastolic (S/D) ratio, middle cerebral artery PI, RI and S/D ratio, Ductus ...
