Fetal Ductus Venosus Flow Velocity Waveforms and Maternal Serum Afp Transabdominal Chorionic Villus Sampling before and after First-trimester
Doppler flow velocity waveform recording in the fetal ductus venosus and umbilical artery as well as maternal blood sampling for serum alpha-fetoprotein (MSAFP) was performed before and after transabdominal chorion Mtlus sampling (TACVS) in 36 women of advanced maternal age (3 36 years). Gestational age ranged between 11 and 13 weeks. No chromosomal anomaly was detected. No statistically sigrul...
متن کاملFirst Trimester Uterine Artery Doppler, Placental Volume and Ductus Venosus Blood Flow as Predictors of Third Trimester Fetal Growth Parameters
To evaluate the potentials of the first trimester uterine artery Doppler, placental volume measurement and ductus venosus blood flow as predictors of third trimester fetal growth parameters. This study was a prospective-observational study, conducted on 200 pregnant women, during a period of 2 years starting from June 1st 2013 till May 30th 2015, in order to evaluate the potentials of the first...
متن کاملCardiac defects in chromosomally normal fetuses with abnormal ductus venosus blood flow at 10-14 weeks.
OBJECTIVE To assess a possible relationship between ductus venosus blood flow abnormalities and cardiac defects in chromosomally normal fetuses with increased nuchal translucency thickness at 10-14 weeks of gestation. METHODS Ductus venosus Doppler ultrasound blood flow velocity waveforms were obtained at 10-14 weeks' gestation immediately before fetal karyotyping in 200 consecutive singleton...
متن کاملPreferential streaming of ductus venosus blood to the brain and heart in fetal lambs.
In 16 chronically prepared fetal lambs we compared the systemic distribution of ductus venosus blood flow with that of abdominal inferior vena caval blood by simultaneously injecting microspheres labeled with different radionuclides into an umbilical vein and into the abdominal inferior vena cava. A significantly greater proportion of ductus venosus blood flow than of abdominal inferior vena ca...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
