Ultrasonographic study of ductus venosus in healthy neonates.
AIM To assess ultrasonographically the flow pattern and the time of postnatal closure of ductus venosus related to the other fetal shunts. METHODS Fifty healthy, term neonates were studied from day 1 up to day 18 using a VingMed CFM 800A ultrasound scanner. RESULTS Ductus arteriosus was closed in 94% of the infants before day 3. Ductus venosus, however, was closed in only 12% at the same ti...
متن کاملDuctus venosus Doppler velocimetry in normal pregnancies from 11 to 13 + 6 weeks' gestation - a Taiwanese study.
BACKGROUND To investigate flow in the ductus venosus at 11-13 + 6 weeks of gestation in women with normal pregnancies in the Taiwanese population. METHODS Two hundred and fifty-two normal singleton pregnancies with gestational ages ranging from 11 to 13 + 6 weeks were examined in this study. The pulsatility index for veins (PIV), resistance index (RI), peak velocity during ventricular systole...
متن کاملContribution of ductus venosus Doppler in first-trimester screening for major cardiac defects.
OBJECTIVE To determine whether assessment of ductus venosus flow at 11-13 weeks' gestation improves the detection rate of cardiac defects achieved by screening with nuchal translucency (NT) thickness. METHODS Prospective first-trimester screening for aneuploidies, including measurement of fetal NT and assessment of ductus venosus flow. The performance of different combinations of increased fe...
متن کاملNeonatal mortality in dogs: Prognostic value of Doppler ductus venosus waveform evaluation - Preliminary results
AIM To define the prognostic value of Doppler ultrasonographic morphology of ductus venosus (DV) waveform on canine neonatal mortality. MATERIALS AND METHODS Fifty-four healthy pregnant bitches underwent fetal ultrasonographic assessment. The DV waveforms were classified as diphasic (dDVw) or triphasic (tDVw) and compared with neonatal mortality. RESULTS Ninety-three fetuses were evaluated....
متن کاملDuctus venosus Doppler in fetuses with cardiac defects and increased nuchal translucency thickness.
OBJECTIVE To examine the possible role of Doppler ultrasound assessment of ductus venosus blood flow in screening for major cardiac defects in chromosomally normal fetuses with increased nuchal translucency (NT) thickness at 11 + 0 to 13 + 6 weeks' gestation. METHODS Ductus venosus blood flow velocity waveforms were obtained immediately before chorionic villus sampling for fetal karyotyping i...
