Fetal anomalies detection in China by screening with ultrasound

Purpose: To correlate sonographic findings of fetal developmental abnormalities resulting from chromosomal aberrations and structural anomalies in 2nd trimester. Design: Cross-sectional study. Setting: Tertiary care centre. Patients and methods: Amid the reporting period from August 2007 to July 2014, prenatal fetal anomaly diagnosis in 9524 fetuses/babies were inspected and contrasted with pos...

Ultrasound evaluation of fetal gender at 12-14 weeks.

AIMS The aim of this study was to assess the feasibility and accuracy of fetal gender assignment by transabdominal ultrasound at 12-14 weeks of gestation. METHODS Fetal gender assessment was performed in 1222 singleton pregnancies. In all fetuses the crown-rump length (CRL) was measured and the genital area of the fetus was examined in the mid-sagittal plane. The result of ultrasound examinat...

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...

Prenatal Ultrasound to Detect Fetal Anomalies

P-226: Non-Invasive Prenatal Screening for Fetal Chromosomal Anomalies in South of Iran

Background: Prenatal diagnosis for Fetal Chromosomal anomalies currently relies on assessment of risk followed by a combination of biochemical and nuchal translucency. Trisomy 21 is the most common trisomy that is associated with intellectual disability. Pregnant women who receive a prenatal diagnosis of trisomy 21 currently have the option of continuing or terminating their pregnancy, but no f...
