摘要
目的 :探讨螺旋CT扫描对主动脉夹层动脉瘤诊断的价值。 方法 :对 12例主动脉夹层动脉瘤患者行螺旋CT扫描。 结果 :横轴位图像上可观察到主动脉壁钙化 ,真、假腔及内膜片、破口位置和受累主动脉范围 ;根据De Bakey分型 ,12例患者中夹层动脉瘤Ⅰ型 3例 ,Ⅱ型 2例 ,Ⅲ型 7例 ;按A、B两型分类为A型 10例 ,B型 2例。 结论 :螺旋CT扫描特别是增强扫描是诊断主动脉夹层动脉瘤首选的影像学方法 ,具有准确、快速、简便及价格低廉的特点 。
Objective:To evaluate the diagnosis of dissecting aneurysm of aorta with helical CT. Methods:Enhanced helical CT scanning was performed on 12 patients with dissecting aneurysm of aorta. Results:On the axial images, the calcification ,the true and false channels and intimal flap、the location of the rupture and the aortic coverage were analysed. According to type of DeBakey, 3 cases were typeⅠ;2 were typeⅡ;7 were typeⅢ and According to type of A、B,10 cases were A;2 were B . Conclusion:Enhanced helical CT scan is the principal method in diagnosis of dissecting aneurysm of aorta. This examination which is very convenient、quick 、accurate and cheap has important significance in choosing therapeutic method and in evaluating therapeutic efficacy .
