产前超声对矫正型大动脉转位的诊断价值
Chinese Journal of Radiological Health（2016）
Abstract
目的 探讨产前超声应用心脏三节段分析法对诊断矫正型大动脉转位(CTGA)的价值.方法 采用心脏三节段分析法对胎儿进行筛查,检出或疑似CTGA胎儿6例,对其超声病例资料进行回顾性分析.结果 6例检出或疑似CTGA的胎儿中,经生后超声心动图或尸检证实有1例为单纯性CTGA,3例为CTGA合并室间隔缺损,1例为CTGA合并室间隔缺损、肺动脉狭窄,1例为CTGA合并室间隔缺损、主动脉弓缩窄,其中1例漏诊肌部室间隔缺损,1例漏诊主动脉弓缩窄.结论 房室连接不一致和心室-大动脉连接不一致是诊断CTGA的关键,仔细观察四腔心切面和左、右室流出道切面是诊断CTGA的重要步骤.心脏三节段分析法是产前超声诊断胎儿CTGA的可靠方法,具有很好的临床应用价值.
