目的：探讨分析产前超声在前脑无裂畸形诊断中的临床价值。方法选取2010年1月至2013年1月接受产前胎儿系统超声检查的15000例孕妇资料进行回顾性分析。结果15000例接受产前胎儿系统超声检查的孕妇中共有11例胎儿被检出存在前脑无裂畸形的现象。其中5例为无叶全前脑畸形，3例胎儿的超声图片显示为半叶前脑无裂畸形，3例胎儿的超声图片信息显示为叶状前脑无裂畸形。合并畸形的情况为3例胎儿为唇腭裂畸形，1例胎儿为无鼻畸形，1例胎儿为眼距畸形，2例胎儿为dandy-w alker综合征。此外还有2例胎儿为羊水多，1例为多囊肾。11例胎儿经过尸检后证实为前脑无裂畸形。结论产前超声检查在前脑无裂畸形诊断中的准确率较高，临床价值较高，值得推广。%Objective To explore the diagnostic value of prenatal ultrasound to fetal holoprosencephaly .Meth-ods A total of 15 000 cases ,receiving ultrasonography examination during Jan .2010 to Jan .2013 in this hospital were chosen to be analyzed .Results Among all 15 000 cases ,11 cases were found as holoprosencephaly ,of which 5 cases were non-forebrain-cleaved deformity ,3 cases were semi- forebrain-cleaved deformity ,and 3 cases were fore-brain-cleaved deformity .3 cases were combined with cleft lips ,1 case was combined with no nose ,1 case was com-bined with eyes distance deformity ,and 2 cases were combined with dandy-walker syndrome .2 cases were polyhydr-amnios ,and 1 case was polycystic kidney .All of the 11 cases were confirmed by corpses .Conclusion The accuracy of prenatal ultrasonography could be high ,and be with important diagnostic value for prenatal diagnosis ,which might be worth to be promoted .
