Four years experience of first-trimester nuchal translucency screening for fetal aneuploidies with increasing regional availability
Background. A prospective screening study was carried out at the regional genetic and perinatal center in South Hungary in order to determine the efficiency of first-trimester nuchal translucency screening for fetal aneuploidies, following augmentation of the availability of nuchal translucency scre...

| 520 | 3 | |a Background. A prospective screening study was carried out at the regional genetic and perinatal center in South Hungary in order to determine the efficiency of first-trimester nuchal translucency screening for fetal aneuploidies, following augmentation of the availability of nuchal translucency screening in the region by the inclusion of newly-trained hospital sonographers. Methods, Nuchal translucency thickness was measured by transvaginal sonography in 7,044 women with singleton or multiple pregnancies at weeks 10-12. Fetal karyotyping was performed when the nuchal translucency was greater than or equal to2.5 mm, and in women with fetuses at high cytogenetic risk. Results. Follow-up was performed in 6,841 of the 7,044 screened women. An abnormal karyotype was found in 33 cases (0.48%). The level of increased nuchal translucency was 4.5% at a cutoff of greater than or equal to2.5 mm, and 2.8% at a cutoff of greater than or equal to3 mm. Seventeen cases of trisomy 21, eight of trisomy 18, four of trisomy 13, one of 45,X, one of triploidy and two cases with other chromosomal abnormalities were detected. In the 33 fetuses with a chromosomal abnormality, the nuchal translucency thickness was <2.5 mm in a case of trisomy 18, greater than or equal to2.5 mm in 32 cases and greater than or equal to3 mm in 28 cases. With cutoffs of 2.5 mm and 3 mm, the sensitivity was 96.97% and 84.85%, respectively. Conclusions. Application of a nuchal translucency thickness cutoff of 2.5 mm is highly efficient for the screening of fetal aneuploidies at 10-12 weeks. This efficiency can be maintained by increasing the regional availability of nuchal translucency screening through the inclusion of newly-trained hospital sonographers. | |
