探讨不同孕周产前超声筛查胎儿畸形的临床意义

摘要

Objective To investigate the clinical significance of different gestational weeks of prenatal ultrasound screening for fetal malformation. Methods From January 2015 to April 2016, 500 cases of pregnant women with prenatal ultrasonography of fetal malformation in our hospital, pregnant women in early pregnancy, second trimester and late pregnancy ultrasound examination of fetal malformations.ResultsAll 500 cases pregnant women, 15 cases of congenital deformity, ultrasound screening results showed that early pregnancy were detected in 1 cases of chromosomal abnormalities,3 cases of fetal malformation, second trimester were detected in 6 cases of fetal malformation, late pregnancy were detected in 4 cases of fetal malformation.Conclusion The early pregnancy ultrasound screening, can effectively detect chromosomal abnormalities, second trimester prenatal examination is an important method of detection period and fetal structural abnormalities, fetal malformations were delayed for effective screening.%目的：探讨不同孕周产前超声筛查胎儿畸形的临床意义。方法选择2015年1月-2016年4月在我院进行产前胎儿畸形超声检查的孕妇500例，孕妇分别于孕早期、孕中期和孕晚期进行超声检查胎儿畸形检出率分析。结果全部500例孕妇中，共15例畸形儿；超声筛查结果显示，孕早期共检出1例染色体异常，3例胎儿畸形；孕中期共检出6例胎儿畸形；孕晚期共检出胎儿畸形4例。结论通过孕早期超声筛查，能对染色体异常进行有效检出，孕中期产前检查是对胎儿结构异常进行检出的重要方法和时期，能对胎儿迟发型畸形进行有效筛查。
