产前系统性超声筛查在中晚期孕妇检查中的诊断价值

目的：探讨产前系统性超声筛查在中晚期孕妇检查中的诊断价值。方法总结和分析仪征市中医院2010年5月至2014年3月对孕22-32周3550例中晚期孕妇进行产前系统性超声筛查结果。结果本组3550例胎儿筛查中，胎儿畸形共80例（2．25％），单发畸形71例，多发畸形9例，其中漏诊5例（0．14％）。在单发畸形中，神经系统畸形17例、泌尿系统畸形12例、心脏畸形10例、消化系统（包括腹部）畸形11例、骨骼系统畸形5例、呼吸系统畸形4例、颈面部8例、其他畸形4例。在漏诊5例中，胎儿复杂心脏畸形1例、腭裂1例、膀胱部分外翻1例、足内翻1例、肛门闭锁1例。结论产前系统性超声筛查对胎儿诊断检查中具有较高特异性和准确性，应作为产前孕妇检查的常规检查手段。

Diagnostic value of systematic prenatal ultrasound screening of pregnant women in the middle and late of pregnancy

Objective To explore diagnostic value of systematic prenatal ultrasound screening of pregnant women in the middle and late of pregnancy. Methods Summary and analysis into 3 550 cases of prenatal ultrasound screening of pregnant women in between 22nd and 32nd of pregnancy. Results Among the 3 550 cases in this arti-cle, 80 of them were fetal anomaly （2.25%）, including 71 single malformation and 9 multiple malformations. Five were missed diagnosed. Single malformation consisted of 17 nervous system malformations, 12 urinary system malforma-tions, 10 heart malformations, 11 digestive system malformations （including abdominal）, 5 skeletal malformations, 4 respiratory system malformations, 8 neck facial malformations, 4 other forms of malformation. Five missed diagnosed cases consisted of 1 congenital heart malformation, 1 cleft palate, 1 partial bladder exstrophy, 1 talipes varus, 1 proc-tatresia. Conclusion Systematic prenatal ultrasound screening has a high value of specificity and accuracy, thus it should be a routine examination for pregnant women.
