MSCT在主动脉夹层的临床应用

Clinical Diagnosis of CT Angiography in Aortic Dissection

目的:探讨MSCT在主动脉夹层的临床诊断应用价值。方法:选取39例来我院进行多层螺旋CTA检查的主动脉夹层患者为研究对象。观察经MSCT后图像并进行三维重建分析。结果:39例主动脉夹层患者中,有De BakeyⅠ型13例、De BakeyⅡ型2例、De BakeyⅢ型20例,不典型夹层4例。39例图像能够清楚成像,主动脉血管分支清晰,夹层动脉位置及范围、管壁病变情况、动脉真假腔及血管壁血栓与病变的空间位置都能很好显示。同时还能表现出内膜血管破口情况。结论:多层螺旋MSCT对主动脉夹层诊断准确、快速,且可以明确分型。MSCT能很好协助临床医生制定对应治疗方案,并为手术提供精准的解剖信息,有着积极的临床意义,值得推广应用。

Objective： To explore the clinical diagnosis effect of CT angiography in aortic dissection. Methods：39 cases of aortic dissection with multi-slice spiral CT were selected as the research object. After CT angiography, the 3D reconstruction results are observed and analyzed. Results：In 39 cases,13 cases of DeBakey type Ⅰ ,2cases of DeBakey type Ⅱ ,and the remaining 20 cases of DeBakey typeⅢ. All cases can clearly show the entire and branch of the aortic, true and false lumen intimal lesions as well as dissecting the location and extent of wall calcification, and mural thrombus and lesion spatial relationships can also be satisfied with the show. Conclusion ：The multi-slice spiral CT angiography can accurately rapid diagnosis of dissecting and genotyping to assist the clinical develop appropriate treatment programs, to provide precise anatomical information for the surgery and the presence of spent deformation there is a very important clinical significance, clinical widely applications.
