彩色多普勒超声在基层医院胎儿畸形筛查中的应用价值

目的 探讨超声诊断在基层医院中对胎儿畸形的临床价值.方法 对17 401例孕11周以上的胎儿分3个阶段进行超声检查,记录胎儿畸形的超声检查结果,与分娩、引产后及部分尸解后结果进行对照.结果 经分娩、引产后及部分尸解后证实的胎儿畸形共170例,超声检出159例,畸形儿发病率为9.77‰,超声诊断符合率为93.52％,漏诊11例,漏诊率为6.47％.结论 超声检查是一种无损伤,可反复检查,价格相对低廉,在胎儿畸形诊断中有重要的临床价值,已成为基层医院产科诊断胎儿畸形的主要工具.

Application Value of Color Doppler Ultrasound for Screening Fetal Abnormalities in Primary Hospitals

Objective To evaluate the clinical diagnosis value of ultrasonic for screening fetal abnormalities in primary hospitals.Methods Ultrasound examination was performed on 17,401 fetuses at 11-39 weeks gestation in three stages,and then examination of fetal abnormalities was recorded and compared with the results after childbirth,postpartum and partial autopsy.Results 130 fetal abnormalities with total of 170 cases were confirmed after childbirth,postpartum and partial autopsy.159 cases were detected using ultrasound,and the rate was 9.14‰,with diagnose accordance rate of 93.52％.11 cases of missed diagnosis accounted for 6.47％.Conclusion Ultrasound is a non-invasive,convenient and inexpensive screening method with an important clinical value in the diagnosis of fetal abnormalities,and has become a major tool for diagnosis of fetal malformations in obstetrics of primary hospitals.
