【摘要】 目的运用CTA影像学探究孤立性外周动脉夹层与主动脉夹层的区别。方法分析我院2014年6月—2017年1月治疗并确诊为动脉夹层的患者80例,其中主动脉夹层患者45例,孤立性外周动脉夹层35例,分别对其影像学特点进行分析。结果孤立性外周动脉夹层(IPAD)的真假腔比值和动脉受累长度小于主动脉夹层患者,差异具有统计学意义(P<0.01)。另外IPAD患者硬化发生率同样小于AD组患者,差异具有统计学意义(P<0.05)。但血管变异程度两组患者差异无统计学意义(P>0.05)。结论孤立性外周动脉夹层在动脉粥样硬化的基础上发生,累及范围窄,真假腔相当,与主动脉夹层CTA不同。更多还原

【Abstract】 Objective To explore the difference between isolated peripheral arterial dissection and aortic dissection using CTA imaging. Methods Eighty patients with dissection were treated in our hospital from June 2014 to January 2017, including 45 patients with aortic dissection and 35 patients with isolated peripheral arterial dissection. The imaging features were analyzed. Results The true and false cavity ratio and the length of arterial involvement of isolated peripheral arterial dissection(IPAD) were significantly smaller than those of aortic dissection, and there was significant difference(P < 0.01). In addition, the incidence of sclerosis in patients with IPAD was also lower than that in AD group(P < 0.05). However, there was no significant difference in the degree of vascular variability between the two groups(P > 0.05). Conclusion Isolated peripheral arterial dissection occurs on the basis of atherosclerosis, involving a narrow range, true and false cavity, and is significantly different from aortic CTA of dissection.更多还原
