摘要
本文分析120例主动脉夹层的影像学所见,着重讨论数字减影血管造影(DSA)应用及其诊断价值,动脉(ⅠA)和静脉数字减影血管造影(ⅣDSA)方法对主动脉夹层主要征象的显示和诊断效果:显示内膜破口和主动脉分支病变,ⅠA法优于Ⅳ法,显示假腔全貌和内膜片负影,Ⅳ法略优于ⅠA法。对Ⅰ或Ⅱ型夹层的诊断ⅠA法明显优于Ⅳ法,Ⅲ型夹层一般Ⅳ法可满足诊断,按手术适应证和治疗的需要可选择应用ⅠA法。结合本组DSA和MRI对主动脉夹层的诊断效用,本文简要讨论了主动脉夹层影像学综合诊断及优选应用问题。
The findings of aortic dissection (AD) with different imaging modalities in 120 cases were analysed in this article with emphasis on the application of digital subtraction angiography (DSA).The capabilities of intravenous (Ⅳ) and intraarterial (IA) DSA in demonstration of the major angiographic signs and diagnostic evaluation for AD might be summarized as follows: IA DSA is superior to Ⅳ in demonstrating intimal entry and re-entry tears as well as aortic branch lesion; while Ⅳ DSA is superior to IA in demonstrating intimal flap and the overall situation of the AD false lumen. For the diagnostic evaluation of DeBakey type Ⅰ and Ⅱ AD lesion, IA DSA is obviously superior to Ⅳ and generally Ⅳ DSA may satisfy the need of diagnostic requirement for type Ⅲ lesion and according to the need of therapeutic, particularly surgical management, IA study may be selectively applied.Based on the merits and demerits of DSA and MRI on the study in the present series, the comprehensive imaging approach and their optimum application in the diagnosis of AD were briefly discussed.
