帆状胎盘69例的超声诊断结果分析

目的 探讨帆状胎盘的超声诊断特点,为临床超声诊断提供参考.方法 对我院2007-2010年69例帆状胎盘的超声诊断情况进行回顾性分析.结果 69例帆状胎盘中,脐带帆状附着42例(占60.9%),前置血管12例(占17.4%),副胎盘型7例(占10.1%),双叶胎盘型4例(占5.8%),双胎型4例(占5.8%).超声诊断帆状胎盘62例,与病理诊断的符合率为88.4%(61/69);误诊为球拍状胎盘5例,误诊率为7.3%(5/69);漏诊3例,漏诊率为4.3%(3/69).孕＜28周的超声与病理诊断符合率为95.6%,孕≥28周的超声与病理诊断符合率为75.0%,两者比较差异有统计学意义(χ2=4.603,P=0.032).结论 彩色多普勒超声是诊断帆状胎盘的重要手段,孕＜28周时帆状胎盘的超声与病理诊断符合率高,对于降低围生儿死亡率、指导临床诊治有重要的意义.
