First- or second-trimester screening should not be performed after NIPT.1 Using NIPT only as a contingent follow-up test avoids invasive testing and its associated risks in most women,29 although some models suggest that as many as one in 50 pregnancies with positive first- or second-trimester screening and normal NIPT results may have an undetected chromosomal abnormality.30 The contingent approach is supported by the Society of Obstetricians and Gynaecologists of Canada.7 ACOG and the Society for Maternal-Fetal Medicine note that NIPT can be used in low-risk populations,1 although positive predictive values are lower. CPC is found in approximately 2 to 4% of fetuses at 16 to 24 weeks of gestation usually as an isolated finding in otherwise normal low-risk pregnancy [1,20]. Proposal of a simple clinical summary for management of specific soft markers in pregnancies.

Fetal Diagn Ther. first-trimester screen, integrated screen, sequential screen, contingent The waiting is awful. Before 10 weeks' gestation, the percentage of fetal vs. maternal cell-free DNA circulating in maternal serum (the fetal fraction) may be too low to create a result. have greatly evolved in the last 2 decades, the relative importance of Cicero et al.

What are the Implications of a Short Fetal Humerus? SUMMARY: Soft markers are ultrasound findings that do not represent a structural anomaly, may be a normal variant, but have been associated with increased risk for fetal aneuploidy. Prenat Diagn. In cases of isolated IEF in euploid fetuses there is no evidence of an altered cardiac function and a detailed echocardiogram is not recommended as long as the second trimester scan is normal [42]. Pediatr Nephrol. We I am going in for a fetal echo at 28 weeks based on the recommendation from mfm. In support of improving patient care, this activity has been planned and implemented by the Postgraduate Institute for Medicine and The ObG Project. recommend a third-trimester ultrasound examination to evaluate growth Echogenic bowel has been described as normal variant, but may be associated with congenital viral infections (particularly CMV), aneuploidy, intra-amniotic bleeding, severe uteroplacental insufficiency, meconium peritonitis, cystic fibrosis, anemia, and fetal growth restriction (FGR) [3,6,13]. First-trimester combined screening is designed to report 5% of all results as positive, most of which will be false positives.
