摘要 目的讨论彩色多普勒超声、多层螺旋CT(multislice spiral CT,MSCT)及MRI对主动脉夹层动脉瘤(aortic disection,AD)的诊断价值,评价3种检查方式的优势与不足,为临床选择检查提供依据。方法回顾性分析2008年1月~2010年6月期间,32例经手术证实为AD患者的彩色多普勒超声、MSCT及MRI检查资料,并与术中所见及病理分型进行对比分析。结果术前彩色多普勒超声检出率为78.1%(25/32),诊断准确率为84%(21/25),MSCT及MRI检出率及诊断准确率均为100%。结论 3种检查方法对AD术前均有较高的诊断价值,彩色多普勒超声术前诊断准确率及检出率低于MSCT及MRI,应存患者病情允许情况下,MSCT及MRI为首选检查方法,若病情危重则以床旁彩色多普勒超声为最佳检查方法,3种检查在临床应用上各有优势与不足,具体选择应视患者病情而定。
