摘要
目的：探讨产前超声检查对先天性肛门闭锁的诊断价值。方法回顾性分析在产前超声筛查中发现肛门闭锁异常征象的出生儿13例的超声声像图特征。结果所有胎儿中未探及肛门“靶环征”声像图的有13例，引产、流产或生后均证实为肛门闭锁。2例为单纯闭锁，11例合并其他畸形及异常，8例出现了肠管扩张，3例肠管内可见强回声的胎粪。结论产前超声筛查能检出胎儿先天性肛门闭锁，但尚缺乏特异性的诊断，胎儿肛门闭锁的产前诊断率仍然很低。
Objective To evaluate the clinical value of prenatal ultrasound in the diagnosis of congenital anal atresia.Methods A retrospective analysis was studied from January 2013 to December 2015 which analyzed abnormal sonographic features by prenatal ultrasound screening in 13 cases of anal atresia.Results 13 cases of anal atresia were confirmed after abortion,miscarriage or birth which were not probed ＆quot;target ring sign＆quot;by prenatal ultrasound screening.That included 2 simple atresia cases and 11 cases associated with other malformations and abnormalities including 8 cases with bowel dilatation and 3 cases with intestine visible echogenic meconium. Conclusion Prenatal ultrasound screening for fetal congenital anal atresia can be detected.But for lacking of specific diagnostic standard,the detection rate of anal atresia remains very low.
