胎儿Dandy-Walker综合征6例分析及文献复习

目的：探讨胎儿Dandy-Walker综合征的超声影像学特征、诊断及处理。方法：总结6例胎儿Dandy-Walker综合征病例，复习有关文献，讨论胎儿Dandy-Walker综合征的超声影像学特征、诊断及处理。结果：6例患者中有3例于妊娠中期超声检查发现胎儿Dandy-Walker综合征，经羊膜腔穿刺胎儿核型分析发现染色体异常后引产，另3例于妊娠晚期超声发现胎儿Dandy-Walker综合征，1例引产，2例分娩后CT检查未发现明显异常。结论：掌握胎儿Dandy-Walker综合征的超声影像学特征，早期识别，及时产前诊断，正确处理，对降低Dandy-Walker综合征胎儿出生率至关重要。

Analysis of Prenatal Dandy-Walker Syndrome in Six Cases and Literature Review

Objective:To investigate the prenatal sonographic features,diagnosis and treatment of Dandy-Walker Syndrome.Methods:Review the literature with the six cases of Dandy-Walker Syndrome to discuss the prenatal sonographic features,diagnosis and treatment of it.Results:At the 2nd-trimster,Dandy-Walker Syndrome was found in three cases via ultrasound,all cases were induced labor with chromosomal abnormalities by amniocentesis.The other three cases among the six cases were found to have Dandy-Walker Syndrome at the 3nd-trimster,one case was induced labor,two cases were found normal via CT after birth.Conclusions:It is important to reduce the birth rate of the Dandy-Walker Syndrome by prenatal ultrasound.
