Screening for fetal aneuploidies at 11 to 13 weeks.
Effective screening for major aneuploidies can be provided in the first trimester of pregnancy. Screening by a combination of fetal nuchal translucency and maternal serum free-β-human chorionic gonadotrophin and pregnancy-associated plasma protein-A can identify about 90% of fetuses with trisomy 21 and other major aneuploidies for a false-positive rate of 5%. Improvement in the performance of f...
متن کاملLearning curve in measurement of fetal frontomaxillary facial angle at 11-13 weeks of gestation.
OBJECTIVE To determine the number of ultrasound examinations required to train sonographers to accurately measure the fetal frontomaxillary facial (FMF) angle at 11-13 weeks of gestation. METHODS Eight sonographers accredited for nuchal translucency thickness (NT) measurement (and with different levels of experience) were trained to measure the fetal FMF angle using specially acquired three-d...
متن کاملChallenges in the diagnosis of fetal non-chromosomal abnormalities at 11-13 weeks.
OBJECTIVE To examine the performance of the 11-13 weeks scan in detecting non-chromosomal abnormalities. METHODS Prospective first-trimester screening study for aneuploidies, including basic examination of the fetal anatomy, in 45 191 pregnancies. Findings were compared to those at 20-23 weeks and postnatal examination. RESULTS Aneuploidies (n = 332) were excluded from the analysis. Fetal a...
متن کاملMaternal thyroid function at 11-13 weeks of gestation in fetal trisomies 21 and 18.
OBJECTIVE To examine the association between maternal serum levels of thyroid stimulating hormone (TSH) and free β-human chorionic gonadotrophin (free β-hCG) in trisomy 21, trisomy 18 and euploid pregnancies at 11-13 weeks and investigate the potential value of TSH in first-trimester screening for aneuploidies. METHODS Maternal serum TSH and free β-hCG levels at 11-13 weeks in 25 trisomy 21 a...
متن کاملFetal RHD genotyping in maternal plasma at 11-13 weeks of gestation.
OBJECTIVE To examine the feasibility of fetal RHD genotyping at 11-13 weeks' gestation from analysis of circulating cell-free fetal DNA (ccffDNA) in the plasma of RhD negative pregnant women using a high-throughput robotic technique. METHODS Stored plasma (0.5 ml) from 591 RhD negative women was used for extraction of ccffDNA by a robotic technique. Real-time quantitative polymerase chain rea...
