产前超声筛查283例胎儿畸形分析

Analysis of 238 Cases of Fetal Abnormalities in Prenatal Ultrasound Dcreening

目的：总结某院产前系统超声筛查情况,分析常见与多发的胎儿畸形种类,探讨连续顺序追踪扫查法对胎儿超声检查的意义,旨在增加基层医院对胎儿先天畸形的认识,提高产前超声筛查业务水平。方法：选取应用连续顺序追踪扫查法对某院2013年1月~2015年12月超声筛查胎儿畸形283例,分析常见与多发胎儿超声声像图特征,随访或分娩后胎儿畸形例数（对照组）与超声诊断例数（试验组）一致例数作对比。结果：随访283例胎儿畸形中239例选择在我院或他院引产,病理检查或解剖符合诊断率达95%,其余继续妊娠直至分娩,多次复查或进一步检查好转,其中多数为孕中期NT增厚经羊水穿刺DNA检查阴性、左心室强光斑、室间隔缺损（多数出生半年左右自然愈合）。总之,随访或分娩后胎儿畸形与超声诊断一致例数达273例,符合率达96.46%,两组对比,差异均有统计学意义（P〈0.05）。结论：采用连续顺序追踪扫查法筛查出胎儿畸形,随访准确率高,误诊与漏诊率大大减少,适合推广与普及,减少胎儿出生缺陷,一定程度上减少医疗纠纷。

Objective：To summarize prenatal ultrasound screening in our hospital,analyze types of common and frequent fetal abnormalities and investigate the importance of continuous order tracking scanning method to fetal ultrasound in order to improving powers of primary hospital employee＇s perception about fetal malformation and the professional skill of prenatal ultrasound screening.Methods：283cases of fetal malformation from ultrasound screening were selected to analyze common and frequent fetal ultrasound ultrasonographic characteristics and following up with fetal abnormalities after childbirth.And then make a comparison and analysis between them.All in all,follow-up or after childbirth fetal abnormalities consistent with ultrasonic diagnosis cases of 273 cases,coincidence rate was 96.46%.Compare the two groups and the difference had statistical significance（P0.05）.Results：Pathological examination or anatomical meet diagnostic rate is more than 95%.Conclusion：It has high accuracy for continuous order tracking scanning method to screening for fetal abnormalities,the rate of missed diagnosis and misdiagnosis is greatly reduced.It＇s suitable for promotion and popularization to reducing birth defects and the medical disputes.
