摘　　要：目的 :研究SCTA和血管仿真内镜在主动脉弓缩窄和离断诊断中的应用价值、检查方法和影像学表现。方法 :对 3例主动脉弓缩窄和离断的患者进行静脉注射对比剂容积扫描 ,利用后处理技术重建成三维图像和仿真内镜图像 ,并经动脉造影和手术证实。结果 :CTA清晰显了纵隔内血管的解剖细节 ,配合血管仿真内镜 ,可对此二种疾病进行分型及诊断。结论 :SCTA及血管仿真内镜作为一种无创性血管造影技术 ,对诊断主动脉弓缩窄和主动脉弓离断有重要价值。Objective:To evaluate the application,imaging techniques and findings of spiral CT angiography(SCTA) and CT virtual endoscopy(CTVE) in coarctation and interruption of aorta.Methods:Three patients with aortic coarctation and interruption of aortic arch were performed spiral CT volumetric scanning with administration of contrast agent.Three dimensional images were reconstructed based on the source data,and resultant reconstructed CTVE were obtained. All of the patients were confirmed by surgery and conventional angiography. Results:SCTA clearly demonstrated the detailed anatomical information of vasculature in mediastinum,by which the aortic coarctation and interruption of aortic arch could be diagnosed and classified on SCTA combined with CTVE.Conclusion:Being a non invasive angiographic technique,SCTA and CTVE are valuable for the diagnosis of the aortic coarctation and interruption of aortic arch.
