摘要
目的 探讨双源CT血管成像技术对主动脉夹层的诊断价值.方法 选择2011年12月～2013年12月在我院进行诊疗的主动脉夹层患者20例为研究对象.使用SIEMENS公司SOMATOM DEFINITION DSCT扫描仪行平扫加增强扫描.结果 20例AD（主动脉夹层患者）按DeBakey分类法分为DeBakey Ⅰ型2例、Ⅱ型2例、Ⅲ型16例.按照Stanford分型法为A型6例、B型14例.“双腔主动脉”即真腔和假腔是AD诊断的主要和直接征象：双源CTA对AD真假腔及内膜瓣的显示率达100％.4例患者假腔内还出现不同程度的血栓,表现为假腔内的充盈缺损.结论 双源CT血管成像技术为诊断主动脉夹层提供了更有利的指导依据,操作简单且具有强大的后处理功能,值得广泛推广和应用.
Objective To evaluate the diagnostic value of DSCT angiography for aortic dissection. Methods Selected 20 Patients with aortic dissection from December 2011 to December 2013 in our hospital,used SIEMENS SOMATOM DEFINITION DSCT scanner line plain and enhanced scan. Results The 20 cases of AD by DeBakey classification into DeBakey type I 2 cases,type H 2 cases,type m 16 cases. According to Stanford type A-type six cases,B-14 cases.＂ Aortic lumen＂ that the true lumen and false lumen was a major and direct signs of AD diagnosis： DSCT CTA for AD true and false lumen and intimal flap display rate＇of 100%. 4 patients had varying degrees of false lumen thrombosis, showed a filling defect of the false lumen. Conclusion DSCT angiography is a noninvasive, simple, quick way to check, while applying the powerful post-processing features for the diagnosis of aortic dissection guide provides a favorable basis, should be popularized and applied.
