产前筛查血清学指标与不良妊娠结局关系的研究进展

Research advances on prenatal maternal serum markers for screening adverse pregnancy outcomes

常规应用于出生缺陷二级预防的孕妇产前筛查血清学指标除了可以预测唐氏综合征、18三体综合征和神经管畸形外，还与其他不良妊娠如胎儿体表及结构异常、妊娠期高血压疾病、妊娠期肝内胆汁淤积症、胎膜早破、流产、死胎、早产、胎儿宫内生长受限及巨大儿等存在一定的相关性。提示异常的产前筛查血清学指标还具有其他不良妊娠结局的预示作用。

The routine prenatal maternal serum testing is widely used for screening of birth defects , including Down syndrome , trisomy 18 syndrome and neural tube defects.The testing results are also associated with other adverse pregnant outcomes such as fetal surface structural abnormalities , gestational hypertension disease , intrahepatic cholestasis of pregnancy , premature rupture of membranes , abortion , stillbirth, intrauterine growth restriction and macrosomia; therefore the abnormal levels of serum markers might be used for predicting these adverse pregnant outcomes .
