Ductus venosus Doppler in screening for trisomies 21, 18 and 13 and Turner syndrome at 11–13 weeks of gestation
Abstract
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 β‐human chorionic gonadotropin and pregnancy‐associated plasma protein‐A. Methods: Screening by the combined test was performed in singleton pregnancies, including 19 614 with euploid fetuses, 122 with trisomy 21, 36 with trisomy 18, 20 with trisomy 13 and eight with Turner syndrome. In all cases the a‐wave in the fetal ductus venosus flow was assessed. We examined the performance of two screening strategies: first, assessment of the a‐wave in all patients and, second, first‐stage screening using the combined test in all patients followed by second‐stage assessment of the a‐wave only in those with an intermediate risk of one in 51 to one in 1000 after the first stage Results: Reversed a‐wave was observed in 3.2% of the euploid fetuses, and in 66.4%, 58.3%, 55.0% and 75.0% of fetuses with trisomies 21, 18 and 13 and Turner syndrome, respectively. Inclusion of ductus venosus flow in all pregnancies would detect 96%, 92%, 100% and 100% of trisomies 21, 18 and 13 and Turner syndrome, respectively, at a false‐positive rate of 3%. The same detection rates were achieved with the two‐stage strategy at a false‐positive rate of 2.6%, in which it was necessary to assess the ductus venosus in only 15% of the total population. Conclusions: Assessment of ductus venosus flow improves the performance of first‐trimester screening for aneuploidies. Copyright © 2009 ISUOG. Published by John Wiley & Sons, Ltd.

In the citing paper
“Additionally, co-evaluation of this parameter along with maternal age, NT, maternal free h-CG, PAPP-A and fetal heart rate increases the detection rates of trisomy 21, 18, 13 and Turner syndrome to 96%, 92%, 100% and 100%, respectively [74].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
