摘要
目的探讨全程CTA检查方法在主动脉夹层诊断和治疗中的价值。方法对63例主动脉夹层动脉瘤病人进行多层螺旋CT平扫及增强扫描,并利用原始数据在Vitrea2工作站进行MPR、MIP、SSD、VR重建。结果按DeBakey分型,表现为Ⅰ型18例,Ⅱ型6例,Ⅲ型39例。重要分支血管受累9例。结论全程CTA扫描方法可以明确主动脉夹层分型;详细评估主动脉及重要分支血管情况,器官受累情况。为临床治疗提供详细影像学依据,有较高的临床应用价值。
Objective To evaluate the diagnosis and the therapy of dissecting aneurys of aorta（AD） with whole aorta-CTA examination. Methods 63 cases with AD were performed with plain scan and contrast enhancement scan by MSCT. All raw data constructions in the Vitrea 2 works tation and reconstuition technique included. MPR, MIP, SSD, VR. Results According to type of DeBakey, 18 cases were type Ⅰ; 6 cases were type Ⅱ; 39 cases were type Ⅲ. 9 cases displayed the important arterial branches involvement. Conclusion The whole aorta-CTA examination can identify the typing of AD, allow the detail evaluation of the aortic and its important branches, and the organ involvement. This method offers detail imaging evidence for clinical therapy and have higher value in clinical application.
