摘要(Abstract)：
主动脉疾病合并心源性休克或术后低心排血量综合征的患者，常需依赖静脉-动脉体外膜肺氧合（VA-ECMO）进行生命支持。在此状态下，明确主动脉病理（如夹层、吻合口漏、新发破口等）对指导治疗至关重要。本文报道3例主动脉疾病体外膜肺氧合（ECMO）患者行主动脉CT血管造影（CTA）的经验，为ECMO患者的主动脉CTA检查提供方法参考。3例患者均为外科手术中置入ECMO,ECMO置入下行主动脉CTA检查，转流方式均为VA-ECMO。2例患者在夹闭ECMO管道状态下完成检查，分别由于对比剂分布不均和显影浅淡，无法达到诊断标准；1例患者在ECMO正常运转下完成检查，造影结果显示对比剂分布均匀，达到诊断标准。患者在VA-ECMO置入状态下能够完成主动脉CTA检查，为临床治疗提供一定参考价值。
