摘要目的:探究NT超声检查在早孕期胎儿畸形筛查中的应用效果。方法:选择2017年3月至2017年12月在我院进行定期产前检查的1280例孕早期孕妇(孕11～13周)为研究对象,均进行二维NT彩超检查,同时追踪孕产妇孕中期二维超声检查结果,并随访至其引产或胎儿娩出后,分析NT超声检查的排畸效果。结果:1280例孕妇中,经NT超声检查发现NT值≥2.5mm有29例,其中有8例孕妇选择引产,其余21例产妇在孕16～18周进行羊水穿刺染色体检测,有6例检出染色体异常进行了引产,而15例孕妇在孕中期(孕24周)进行二维超声发现4例胎儿畸形,选择了引产,余下11例孕产妇分娩出正常胎儿。经分析发现,NT超声诊断胎儿畸形的敏感性为38.09%、特异性100.0%、阳性预测值100.0%、阴性预测值52.38%,准确率99.14%。结论:孕早期进行NT超声检查筛查胎儿畸形准确率较高,有助于临床及时处理胎儿畸形问题,最大程度降低胎儿畸形对孕妇身心健康的影响,具有较好的社会意义。
