目的 探讨开展产前系统超声筛查的临床价值.方法 回顾性分析产前系统超声筛查对胎儿畸形的检出率,及其孕周分布、系统分布等特点.结果 接受产前系统超声检查的3910胎中,84胎被诊断为畸形.孕周以15～27周为主(50/84,59.52％)；严重畸形54胎(54/84,64.29％)；单发畸形52胎(52/84,61.90％).胎儿各系统畸形中,以神经系统畸形最常见(16/84,19.05％),其次为心血管系统(13/84,15.48％)、生殖泌尿系统(12/84,14.38％)等.结论 产前系统胎儿筛查能发现胎儿畸形,减少出生缺陷.%Objective To observe the clinical value of prenatal systematic ultrasonic screening in diagnosis of fetal malformations. Methods The detection rate of fetal malformations with prenatal systematic ultrasonic examination was calculated, and getational age distribution, systems distribution and so on were analyzed retrospectively. Results Totally 3910 fetuses underwent prenatal systematic ultrasonic examination, among them 84 were diagnosed as abnormal. The gestational weeks distributed mainly in 15-27 weeks (50/84, 59.52%). Serious deformations were found in 54 fetuses (54/84, 64. 29%) , and single malformation was found in 52 fetuses (52/84, 61. 90%). Nervous system malformations were most common (16/84, 19.05%), followed by cardiovascular system (13/84, 15.48%) and genitourinary system (12/84, 14. 38%) etc. Conclusion It is necessary to promote prenatal systematic ultrasonic examination in general hospitals in order to detect fetal malformations and reduce birth defects.
