产前超声早期诊断胎儿前腹壁异常的临床意义

目的探讨早孕及中孕早期超声诊断胎儿前腹壁异常的临床意义。方法回顾性分析我院早孕及中孕早期超声诊断的21胎前腹壁异常胎儿超声表现及随访结果,分析比较前腹壁异常的超声声像图特征。结果早孕及中孕早期超声筛查出21胎胎儿前腹壁异常,均在首次超声检查时发现,均经引产直接观察或病理检查进一步证实;其中脐膨出12胎,泄殖腔外翻1胎,体蒂异常8胎。7胎接受羊水穿刺检查,1胎脐膨出为13-三体,余染色体未见异常。结论早孕及中孕早期超声检查可有效诊断及鉴别诊断前腹壁异常,具有重要临床意义。

Clinical value of prenatal ultrasound screening in early diagnosis of anterior anomaly of abdominal wall

Objective To observe clinical valve of prenatal ultrasonography in first and early second trimester for diagnosis of anterior anomaly of abdominal wall. Methods A retrospective study was performed in 21 fetuses with anterior anomaly of abdominal wall in first and early second trimester, including the time of preliminary diagnosis, ultrasonic findings, and follow-up results. The ultrasonic features were analyzed. Results All 21 fetuses were diagnosed with anomaly of abdominal wall by ultrasound in first and early second trimester, including 12 omphalocele, 1 cloacal exstrophy and 8 body stalk anomaly. Seven of the 21 fetuses underwent amniocentesis, and 1 fetus of omphalocele was diagnosed as 13-trisomy, the others were normal. Conclusion Prenatal ultrasonography in first and early second trimester is effective to diagnose fetal anterior anomaly of abdominal wall.
