摘　　要：目的:探讨穿透性粥样硬化性主动脉溃疡和主动脉壁间血肿CTA的影像学表现。方法:搜集27例穿透性主动脉溃疡和主动脉壁间血肿病例,对其CTA影像学特征进行分析。结果:单发溃疡24例,3例为多发溃疡。主动脉溃疡伴壁间血肿19例。CT扫描表现为主动脉壁局限性溃疡,有时表现为口部与主动脉腔延续处"狭颈征";壁间血肿时,CT表现为主动脉周围低密度影环绕,无强化。结论:无创性CTA是临床疑诊断PAU和AIH的首选检查方法。Objective：To study the CT angiography （CTA） features of penetrating atherosclerotic aortic ulcer and aortic intramural hematoma. Methods： 27 cases of penetrating atherosclerotic aortic ulcer and aortic intramural hematoma were recruited,their CTA characteristics were analyzed. Results： Of the 27 patients,there were single aortic ulcer （24 patients） ,multiple aortic ulcers （3 patients） and aortic intramural hematoma （19 cases）. The CTA findings of penetrating atherosclerotic ulcer were local defect or excavation of aortic wall, sometimes with ＂narrow neck sign＂ at the broken intima. In aortic intramural hematoma,there were hypodense attenuation surrounding aorta with no enhancement. Conclusion： CTA is non-traumatic and is the first choice in the diagnosis of penetrating atherosclerotic aortic ulcer and aortic intramural hematoma.
