规范化中孕期超声筛查胎儿畸形的临床价值

Clinical Value of Standardized Ultrasound Screening for Fetal Abnormality in Second Trimester

目的探讨规范化中孕期超声筛查胎儿畸形的临床价值。方法2003年1月至2005年5月间对7 741例孕妇进行了中孕期超声筛查,系统地检查胎儿头颅、颜面部、脊柱、心脏、腹部脏器、四肢、脐动脉等结构,重点观察胎儿心脏和颜面部,每个孕妇采集9张标准图片。结果检出胎儿畸形218例257项畸形,161例经引产、尸检或出生后证实。超声漏诊16项畸形,漏诊率为5.9%。结论规范中孕期超声筛查胎儿畸形的操作流程,采集标准的图片和规范超声报告的格式,对尽可能地检出胎儿畸形、减少漏诊率、降低医疗风险具有重要的临床意义。

Objective To evaluate the clinical value of standardized ultrasound screening for fetal abnormality in second trimester. Methods During the period of Jan. 2003 and May 2005, 7 741 pregnancy women were subjected to ultrasound screening in second trimester in our hospital. The structures, such as the head, lips, spine, heart, abdominal organs, limbs and umbilical arteries, were scanned in detail. The lips and heart of the fetus were focused. Results 218 fetus with 257 congenital abnormalities were detected by ultrasound screening and 161 were confirmed by autopsy or after birth. However, 16 abnormalities （5.9%） were failed to report. Conclusion Standardized ultrasound screening in second trimester is of great value to screen fetal abnormality, which can reduce the risk of medical treatment in fetal abnormality screening.
