孕早期经腹超声筛查胎儿及附属结构异常的临床价值

目的：探讨经腹超声在孕早期筛查胎儿及附属结构异常中的临床价值。方法采用经腹部超声对7663例11～13＋6周孕妇进行产前筛查，发现胎儿及附属结构异常并继续妊娠者行中期超声检查，随访其结果。结果7663例孕妇（7806例胎儿）中，共检出142例胎儿及附属结构异常（1.8％），其中死胎1例，20例选择引产，24例失访，85例继续妊娠者孕中期超声发现异常11例。结论孕早期经腹超声能筛查出部分胎儿异常，应结合中孕期超声检查，为临床提供有力的诊断价值。

Clinical value of abdominal ultrasound in diagnosis of fetal and ancillary structural abnormalities at early trimester

Objective To explore the clinical value of abdominal ultrasound diagnosis of fetal and ancillary structural abnor -malities.Methods Total of 7633 pregnant women between 11~13＋6 weeks of gestation received abdominal ultrasound scan .The cases with structural abnormalities further received ultrasound screening during the second trimester .Clinical outcomes were followed up .Re-sults Among the 7806 fetuses, 142 cases with abnormal fetal and adjacent structures were detected by ultrasound during the first tri -mester （1.8%）.Of the abnormalities, one fetus was dead in uterus and 20 were treated with induced labor.There were 24 cases missed during the follow-up.Of rest 85 cases, 11 abnormal cases were further confirmed by ultrasound screening during the second tri -mester.Conclusion Abdominal ultrasound screening in the first trimester can effectively detect some abnormal fetuses .Combination of the second trimester ultrasound screening can provide powerful diagnostic value .
