经腹部超声与经阴道超声诊断孕11～14周胎儿畸形的对比分析

摘要

Objective To investigate the clinical value of transvaginal ultrasonography and transabdominal ultrasonography in the diagnosis of fetal structural abnormalities at 11-14 weeks of gestation.Methods 22 pregnant women with fetal structural abnormalities at 11-14 weeks of gestation admitted in our hospital form April 2013 to February 2015 were randomly selected,all abnormal fetuses were confirmed by odinopoeia and autopsy.22 pregnant women underwent transvaginal ultrasonography and transabdominal ultrasonography,and the detection outcome of abnormal fetuses by two inspecting methods was observed,recorded,compared and analyzed.Result The detectable rate of fetal structural abnormalities by transvaginal ultrasonography was 96.77％ (30/31),which was significantly higher than 58.06％ (18/31) by transabdominal ultrasonography,with statistically significant difference (P＜0.05).Conclusion Transvaginal ultrasonograpy can effectively improve the detectable rate of fetal structural abnormalities of early pregnant stage,but transabdominal ultrasonography still has very important value of screening in late pregnant stage.%目的 探讨经阴道超声和经腹部超声在孕11 ～ 14周胎儿畸形诊断方面的临床价值.方法 随机选取本院2013年4月至2015年2月收治的孕11～14周胎儿畸形孕妇22例,所有畸形胎儿均经由引产尸检得到确认.对22例孕妇分别进行经阴道超声检查和经腹部超声检查,观察并记录两种检查方式对畸形胎儿的检出情况,并对其进行对比分析.结果 经阴道超声检查的胎儿畸形检出率为96.77％(30/31),明显高于经腹部超声的检出率58.06％(18/31),差异有统计学意义(P＜0.05).结论 经阴道超声检查能够有效提高孕早期胎儿畸形的检出率,但是对于孕周较大胎儿,经腹部检查仍具有十分重要的临床筛查价值.
