摘　　要：目的探讨64排螺旋CT全程、双期扫描结合重建技术在主动脉夹层诊断中的应用。方法对40例主动脉夹层病人的64排螺旋CT扫描血管成像资料进行回顾性分析。结果 40例全部能辨别真假腔,按De-BaKey分型属于Ⅰ型17例,Ⅱ型1例,Ⅲ型22例。25例显示破口,主动脉弓3大分支或部分分支受累13例,累及腹腔干6例,累及肠系膜上动脉5例,累及右肾动脉7例,累及左肾动脉12例,累及髂动脉19例。并发心包积液7例,胸腔积液13例,肺动脉栓塞1例。结论 64排螺旋CT全程、双期扫描结合重建技术能够明确诊断主动脉夹层,具有较高临床应用价值。Objective To discuss the application of 64-slice spiral CT in the diagnosis of dissection aorta by double-phase scanning on whole aorta combined with reconstruction technique. Methods Vascular imaging data of 64-slice spiral CT in 40 patients with aortic dissection were analyzed retrospectively. Results Real and false lumens were identified in all 40 cases studied.Of whom,those belonged to DeBakey types Ⅰ,Ⅱ and Ⅲ were 17,one,and 22 cases,respectively.The leakages were found in 25 patients.Involvement of the three main branches of aortic arch or part of them were showed in 13 cases,celiac artery trunk in six,superior mesenteric artery in five,right renal artery in seven,left renal artery in 12,and iliac artery in 19;Seven cases were complicated with pericardial effusion,13 with pleural effusion,and one with pulmonary embolism. Conclusion By double-phase scanning of whole aorta combined with reconstruction technique,64-slice spiral CT shows a high clinical value in detection of aortic dissection.
