Prevalence and outcome of absence of ductus venosus at 11(+0) to 13(+6) weeks.
INTRODUCTION To examine the prevalence and outcome of absent ductus venosus (DV) diagnosed at 11-13 weeks' gestation. METHOD Prospective screening study for aneuploidies in 65,840 singleton pregnancies, including measurement of nuchal translucency (NT) thickness and examination of the DV. Prenatal findings and outcome of fetuses with absent DV were examined. RESULTS Absent DV was diagnosed ...
متن کاملA mixture model of ductus venosus pulsatility index in screening for aneuploidies at 11-13 weeks' gestation.
OBJECTIVE To assess the value of ductus venosus pulsatility index for veins (DV PIV) in screening for aneuploidies at 11-13 weeks' gestation. METHODS Fetal DV PIV was measured in singleton pregnancies undergoing first-trimester screening for aneuploidies. In euploid (n = 44,756) and aneuploid (202 cases of trisomy 21, 72 cases of trisomy 18 and 30 cases of trisomy 13) fetuses, DV PIV was best...
متن کاملLearning curve for Doppler assessment of ductus venosus flow at 11 + 0 to 13 + 6 weeks' gestation.
OBJECTIVE To determine the number of scans necessary for training sonographers to examine accurately the ductus venosus at 11 + 0 to 13 + 6 weeks' gestation. METHODS Ten sonographers with prior extensive experience in the measurement of nuchal translucency thickness were given practical training in the accurate assessment of the ductus venosus. They were then asked to examine the ductus venos...
متن کاملFrontomaxillary facial angle in fetuses with trisomy 13 at 11 + 0 to 13 + 6 weeks.
OBJECTIVE To investigate the frontomaxillary facial (FMF) angle in fetuses with trisomy 13 at 11 + 0 to 13 + 6 weeks of gestation. METHODS A three-dimensional (3D) volume of the fetal head was obtained before karyotyping at 11 + 0 to 13 + 6 weeks of gestation in 23 fetuses with trisomy 13. The FMF angle, defined as the angle between the upper surface of the maxilla and the frontal bone in a m...
متن کاملDuctus venosus Doppler in screening for trisomies 21, 18 and 13 and Turner syndrome at 11-13 weeks of gestation.
OBJECTIVES To investigate the performance of first-trimester screening for aneuploidies by including assessment of ductus venosus flow in the combined test of maternal age, fetal nuchal translucency thickness, fetal heart rate, and serum free beta-human chorionic gonadotropin and pregnancy-associated plasma protein-A. METHODS Screening by the combined test was performed in singleton pregnanci...
