摘　　要：目的评价多层螺旋CT血管造影(MSCTA)对主动脉夹层术前诊断和腔内隔绝术后评估的价值。方法应用多层螺旋CT对25例主动脉夹层患者进行检查诊断,并行主动脉腔内隔绝术前评估及术后随访,将结果与DSA造影进行比较。结果与动脉瘤腔内隔绝术前DSA对照,MSCTA对主动脉夹层的诊断符合率达100%,依据其测量数据选定的内膜支架规格、型号、经手术证实完全符合要求,MSCTA共显示破口50个,DSA显示破口31个;两者在显示破口方面差异有统计学意义(χ2=5.959,P=0.015),术后随访有1例发生内漏,发生率为4%。结论多层螺旋CT血管造影对主动脉夹层的诊断、主动脉腔内隔绝术及术后评估的价值要优于DSA,可作为首选的影像检查手段。[Objective] To evaluate the application and evaluation of multi-slice spiral CT angiography before and after intervention therapy of＇ aortic dissection. [Methods] Multi-slice CT angiography was per-formed in 25 eases with aortic dissection, all patients were treated in endovascular graft exclusion. MSCT were performed in the preoperative evaluation and postoperative tbllow-up. The results were compared with DSA checking. [Results] Compared with DSA, the diagnostic accordance rate in MSCT were reached to 100%. The stent grafts according to the parameters, obtained by MSCT prior EVGE procedure, measured per-fectly to need of implantation. MSCT showed 50 entry tears in all cases, DSA showed 31 entry tears. The statistic analysis was taken at the same time, the difference in displaying the entry tears in two kinds of scan was highly significant in statistic （X^2=5.959, P=0.015）, the leakage occurred in 1 case （4%） after operation. [Conclusion] MSCT is of high value to the diagnosis of aortic dissection, preoperative evaluation and postop-erative follow-up of endovascular grail exclusion, it was better than DSA, it also can be used as a iirst-choice imaging method.
