摘要
目的：探讨孤立性外周动脉夹层与主动脉夹层的不同影像学特点。资料与方法：回顾性分析22例孤立性外周动脉夹层和25例主动脉夹层患者的CTA图像，对比其影像学特征。结果：主动脉夹层和孤立性外周动脉夹层CTA图像均可清晰分辨真腔、假腔及夹层累及动脉长度。两组大部分患者伴有不同程度动脉硬化表现。两组间比较，假/真腔比值、动脉受累长度、动脉硬化发生率组间差异有统计学意义，P＜0.05。结论：孤立性外周动脉夹层往往在动脉粥样硬化基础上发生，受累动脉局限，真腔往往大于假腔，病情相对稳定，其影像学表现与主动脉夹层存在明显不同。
Abstract
Objective: To investigate the different imaging features between isolated peripheral arterial dissection and aortic dissection. Materials and Methods: CTA images were retrospectively analyzed for isolated peripheral arterial dissection in 22 cases and aortic dissection in 25 cases, and then imaging features were compared. Results: The true lumen, false lumen and involved length of arterial dissection could be clearly distinguished from CTA images of aortic dissection and isolated peripheral arterial dissection. Most patients of the two groups could be found varying degrees of atherosclerosis. Between the two groups, there were statistically significant difference in the ratio of false-true lumen, the involved length of artery and the incidence of atherosclerosis, P<0.05. Conclusion: Isolated peripheral artery dissection often occurred on the basis of atherosclerosis, and the affected artery was limited, and the true lumen is often greater than the false lumen. Its condition was relatively stable, and its imaging features existed obvious differences from aortic dissection.
