摘要
目的探讨双源CT诊断主动脉夹层的影像学特征及其术前评价价值。方法收集35例主动脉夹层患者的双源CT血管成像检查资料,所有患者的图像分析及后处理工作均在工作站上完成,重建方法包括多平面重建(MPR)、最大密度投影(MIP)、容积再现技术(VR)等。重点观察主动脉夹层的范围、分型及重要分支受累情况等。结果依据夹层累及范围,35例患者包括DeBakeyⅠ型13例,DeBakeyⅡ型4例,DeBakeyⅢ型18例,所有患者均观察到撕裂的内膜片及近端初始破口的位置,并准确显示了主动脉重要分支血管的受累情况。结论双源CTA检查操作简便,综合原始及各种后处理图像可以准确诊断并评价主动脉夹层情况,是主动脉夹层诊断及随访的重要影像学检查方法之一。
Objective To investigate the clinical value of dual-source CT(DSCT) angiography in the diagnosis and preoperative assessment of aortic dissection.Methods Thirty-five patients with aortic dissection from Jul 2009 to Feb 2011 were retrospectively analyzed.Imaging reconstruction and analysis of all patients were finished at the workstation.The reconstruction techniques included multiplanar reconstruction,maximum intensity projection,and volume rendering technique.The extension,type,and involvement of important branches of aortic dissection were focused.Results According to involvement extension of aortic dissection,there were 13 cases of DeBakey type I,4 cases of DeBakey type II and 18 cases of DeBakey type Ⅲ.Lacerated intimal flap and initial entry site of aortic dissection were observed in all patients,and involvements of main branches of aorta were accurately showed.Conclusions DSCT angiography should be one of important imaging Methods in diagnosis and preoperative assessment of aortic dissection,for its simple operation and accuracy.
