The value of combined detailed first- trimester ultrasound– biochemical analysis for screening fetal aneuploidy in the era of non-invasive prenatal testing

2023-08-03

Abstract excerpt

<h4>Purpose: </h4> This study aimed to investigate the performance, cost-effectiveness and additional findings of combined detailed ultrasound and biochemical screening for risks of major fetal trisomies in the first- trimester. Methods This is a retrospective analysis study, we estimated the risk of trisomies 21, 18 and 13 based on maternal age, fetal nuchal translucency thickness, nasal bone, ductus venosus pul...
