AbstractAltered flow in ductus venosus (DV) may be caused by the changes in preload or afterload. Its association with aneuploidy and congenital heart defects (CHDs) was widely described.The aim of this study was to examine the incidence of a reversed a-wave in DV flow (revDV) and the absence of DV (noDV), their coincidences with other markers of aneuploidy or fetal abnormalities in a mixed-risk population.The study group covered women who underwent an ultrasound scan between 11+0 and 13+6 weeks’ gestation.Singleton pregnancies with known pregnancy outcome and a crown-rump length of 45–84 mm.A total of 5811 cases, including 137 aneuploidies, met the inclusion criteria: 35 subjects of noDV, 189 of revDV and 5587 of normal DV flow. The incidence of noDV in euploidy was 0.47%, and in aneuploidy 5.8%. The incidence of revDV in euploidy was 2.46%, and in aneuploidy 35.7%. Among aneuploidy, the highest prevalence of noDV was found in monosomy 45X. revDV showed the highest prevalence in trisomy 18. Isolated noDV was only found in euploidy. Isolated revDV subjects were only observed in euploidy and trisomy 21. Any combination of revDV with additional markers showed high incidence in major trisomies. Extracardiac anatomy and abnormal cardiac findings showed a higher prevalence in noDV and revDV cases.The presence of noDV might be useful in suspicion of monosomy X among cases with increased nuchal translucency, as well as in differentiating them from other aneuploidies. The combinations of aneuploidy markers with revDV are strong indicators of aneuploidy. revDV alone is a poor screening tool for aneuploidy and euploidy with CHD.

AbstractObjectivesTo identify the most common ultrasound patterns of markers and anomalies associated with Patau syndrome (PS), to explore the efficacy of multiparameter sonographic protocols in detecting trisomy 13 (T13) and to analyze the influence of maternal age (MA) on screening performance. Methods: The project was a prospective study based on singleton pregnancies referred for a first-trimester screening examination. The scan protocol included nuchal translucency (NT), fetal heart rate (FHR), secondary ultrasound markers [nasal bone (NB), tricuspid regurgitation (TR), ductus venosus reversed a-wave (revDV)] and major anomaly findings. Results: The study population comprised 6133 pregnancies: 6077 cases of euploidy and 56 cases of T13. Statistically significant differences were found in MA, FHR, NT, absence of NB, presence of revDV, TR and single umbilical artery. Fourteen cases of T13 (25%) demonstrated no markers of aneuploidy. The best general detection rate (DR) (DR of 78.6% with an false positive rate (FPR) of 1.2%) was obtained for a cutoff of 1/300 utilizing the “NT+T13” algorithm. The logistic regression model revealed that the central nervous system (CNS) anomalies had the greatest odds ratio (of 205.4) for T13. Conclusions: The effectiveness of the multiparameter sonographic protocol used for T13 screening showed promising results in patients older than 36 years and suboptimal results in patients between 26 and 36 years old. When screening for T13 left heart defects, CNS anomalies, abdominal anomalies, FHR above the 95th percentile, increased NT, revDV and lack of NB should receive specific attention.
