摘要
目的：探讨中孕早期（14～17周）超声规范检查的临床价值。方法：对2009年1月～2013年6月在我院超声科接受超声检查，孕周处于14～17周孕妇的病例，进行回顾分析，并跟踪随访全部病例的妊娠结局。结果：3550例胎儿中，发现结构异常的胎儿34例（27例单发畸形，7例多发畸形，其中2例发生于双胎妊娠）；软指标异常25例，均在孕28周前消失。阴性病例后期出现3例四肢短小，6例肾盂分离，2例脑室系统轻度增宽，8例单纯侧脑室后角轻度增宽。结论：中孕早期（14～17周）的胎儿超声检查可以准确诊断大部分结构异常，弥补了前期检查为空白的缺憾，是一种有效的筛查方法。
Objective：To assess the clinical value of standardized diagnostic ultrasonography for screening the birth defects in the early stages of second tri-mester of pregnancy（week 14-17）.Methods：The ultrasonic findings were retrospectively examined in 3350 pregnant women during their second-trimes-ter undergone ultrasonography in our department between January 2009 and June 2013,and all patients were followed up concerning their pregnancy out-comes.Results：Of the 3350 cases,structural abnormalities were found in 34 （ single deformity in 27;multiple malformation in 7 in which 2 being associat-ed with twins）,and abnormal ultrasonographic soft markers in 25,which disappeared before the 28th week of pregnancy.In the negative ultrasonic find-ings,three cases were associated with micromelia,6 with separation of the fetal renal pelvis,2 with mild broadened ventricular system,and 8 with simple widened lateral cerebral ventricles at the posterior angle in mild manner occurred in later stages .Conclusion：Diagnostic ultrasound in the early stage of second trimester of pregnancy may reveal the structural abnormalities in majority of the birth defects ,which may serve as a supplement tool for effective screening the birth defects in this stage of pregnancy .
