“…In fact 60% of the fetuses had an enlarged NT. In order to avoid unnecessary exposure of young fetuses to Doppler energy and because of limitations concerning time, expertise and equipment, we do not perform Doppler velocimetry routinely in all patients attending our clinics 18,19 . Therefore these results cannot be extrapolated to a general obstetric population.…”

“…The authors conclude that further studies are needed to investigate the role of ductus venosus Doppler in a low-risk population. However, in such a low-risk population it will be difficult to obtain informed patient consent, which is the prerequisite for ethical approval and publication of such studies 12 . In continuing pregnancies, unbiased information on the potential bioeffects of color and pulsed Doppler investigation during the first trimester has to be provided to the mother-to-be.…”

Objective: The aim of this study was to examine the possible role of Doppler ultrasound assessment of ductus venosus (DV) blood flow at 11⁺⁰–13⁺⁶ weeks’ gestation in fetuses with normal nuchal translucency (NT) in screening for autosomal trisomies (AT) and for congenital heart diseases (CHD) in chromosomally normal fetuses. Methods: First-trimester combined screening for trisomy 21 (T21) was carried out prospectively for 7 years in singleton pregnancies. NT and the pulsatility index for DV (DVPI) were calculated. The DV was analyzed according to its association with AT and CHD. The detection rate (DR), false-positive rate (FPR), positive predictive value (PPV), and odds ratio (OR) for abnormal DV were calculated. Results: Abnormal DV as an early marker of euploid CHD gives a DR of 12.5%, an FPR of 4.3%, a PPV of 1.4%, and a negative predictive value (NPV) of 99.5%, with an OR of 3.1 (95% CI 1.3–7.4). Moreover, abnormal DV as an early marker of AT shows a DR of 35.7%, an FPR of 4.3%, a PPV of 1.2%, an NPV of 99.9%, and an OR of 12.3 (95% CI 4.1–36), and the values are 33.3, 4.3, 0.97, and 99.9% and 11 (95% CI 3.2–36.9), respectively, for T21. Conclusions: Our data supports the association between increased DVPI and CHD or AT. The sensitivity of this marker is not strong enough to be used a screening test.
