Ultrasonographic diagnosis of fetal structural abnormalities in prenatal screening at 11-14 weeks.
PURPOSE The aim of the study was to determine the detection rate of structural abnormalities at the 11-14 week ultrasound examination as a part of two-stage screening process in low-risk pregnancies. MATERIALS AND METHODS A total of 1085 consecutive low-risk pregnant women participated in screening by two-stage ultrasonography for the estimation of the sensitivity of the first and second trim...
متن کاملIncreased fetal nuchal translucency at 11-14 weeks.
Nuchal translucency (NT) is the sonographic appearance of a subcutaneous collection of fluid behind the fetal neck. The measurement of fetal NT thickness at the 11-14-week scan has been combined with maternal age to provide an effective method of screening for trisomy 21; for an invasive testing rate of 5%, about 75% of trisomic pregnancies can be identified. When maternal serum free-beta human...
متن کاملFetal cardiac abnormalities identified prior to 14 weeks' gestation.
OBJECTIVE An increasing number of patients are presenting at early gestational age as being at high risk for congenital heart disease, as a result of ultrasound screening by nuchal translucency. The feasibility and accuracy of fetal echocardiography was assessed in a series of pregnancies studied before 14 weeks' gestation. METHODS Echocardiography was attempted in 478 fetuses of crown-rump l...
متن کاملDetection of sex chromosome abnormalities by nuchal translucency screening at 10-14 weeks.
At 10-14 weeks of gestation more than 80 per cent of fetuses affected by trisomy 21 can be detected by a screening programme based on a combination of maternal age and fetal nuchal translucency thickness (NT). The screen positive group in such a programme also identifies fetuses with sex chromosome abnormalities. In this ongoing multicentre screening study, involving 61,972 singleton pregnancie...
متن کاملScreening for chromosomal abnormalities at 10-14 weeks: the role of ductus venosus blood flow.
OBJECTIVE To assess the possible role of Doppler ultrasound assessment of ductus venosus blood flow in screening for chromosomal abnormalities at 10-14 weeks of gestation. METHODS Ductus venosus flow velocity waveforms were obtained immediately before fetal karyotyping in 486 consecutive singleton pregnancies at 10-14 weeks of gestation. All cases were screened for chromosomal defects by a co...
