摘要目的:探讨中孕期胎儿超声软指标阳性的临床意义。方法:选取庐江县人民医院2019年2－11月行产前超声检查的中孕期孕妇486例的临床资料，对产检超声检查提示阳性的209例共244项单项阳性指标进行回顾性分析。结果:486例孕妇中检出阳性指标209例，阳性率43.0%(486/209)；阳性单项244项中，胎儿畸形或缺陷10项，占4.10%；胎儿附属物阳性106项，占43.44%；胎儿软指标阳性128项，占52.46%。结论:产前超声检查提示阳性中，超声软指标占大多数，运用超声软指标预测胎儿染色体风险，不宜过度解读，防止导致孕妇和近亲属恐慌，选择有创性产前诊断技术，造成检查过度，在一些基层医疗机构甚至采取人工终止妊娠，给母胎带来不必要的伤害。

abstractsObjective:To explore the clinical significance of fetal ultrasound soft index positive in middle pregnancy.Methods:The clinical data of 486 pregnant women who were examined by prenatal ultrasound from February 2019 to November 2019 in the People's Hospital of Lujiang County were collected, and a retrospective analysis was made in 244 single positive indicator in 209 pregnant women who were positive by prenatal ultrasound.Results:Among 486 pregnant women, 209 cases were positive, with a positive rate of 43.0%(486/209). Among 244 positive items, 10 items were fetal malformation or defect, accounting for 4.10%; 106 items were fetal appendage, accounting for 43.44%; 128 items were fetal soft index, accounting for 52.46%.Conclusion:The soft index of ultrasound is the majority of the positive results in prenatal ultrasound examination.It is not suitable to over interpret the soft index of ultrasound to predict the risk of fetal chromosome, so as to prevent the panic of pregnant women and their families.The invasive prenatal diagnosis technology is chosen to cause over examination, and even to terminate pregnancy manually in some basic medical institutions, which will bring unnecessary harm to the mother and fetus.
