摘要

Numerous studies have described the association between EIF and aneu-ploidy, specifically Down syndrome.12 Meta-analyses of studies conducted primarily in high-risk pregnancies reported that the risk of trisomy 21 was increased 1.8- to 5.4-fold by the finding of an isolated EIF.3-12'13 Recently, another meta-analysis similarly identified a 2.9 likelihood ratio (LR) for isolated EIF, when defined as no major abnormalities and no evidence of ventriculomegaly, increased nuchal skinfold thickness, echogenic bowel, pyelectasis, short humerus, or short femur
