摘　　要：目的:探讨320排螺旋CT血管成像(CTA)在主动脉夹层(AD)影像学诊断中的价值。方法:使用320排螺旋CT血管成像技术对112例AD患者进行平扫加增强,统计AD分型,受累的动脉分支,初次、再次破口次数及观察撕裂内膜征象。结果:112例AD患者中,De BakeyⅠ型占33.0%(37/112),Ⅱ型占12.5%(14/112),Ⅲ型占54.5%(61/112);受累头臂干动脉占15.1%(17/112)。撕裂内膜片占96.4%(108/112),真假双腔显影100%(112/112),内膜钙化移位占41.1%(46/112);初始破口占93.7%(105/112);再次破口占7.1%(8/112)。结论:320排螺旋CT血管成像技术具有快速、准确诊断的优点,是诊断AD及明确分型的可靠影像学检查之一。Objective： To evaluate the imaging diagnosis value of 320-slice spiral CT angiography in aortic dissection. Methods： A total of 112 AD patients were enrolled in this study using 320-slice spiral CT angiography. The AD classification,the number of arterial branches involved,the number of times of recurrence and the observation of endometrial features were observed. Results： Of the 112 AD patients,De Bakey type I accounted for 33. 0%（ 37/112）,type II 12. 5%（ 14/112）,type III accounted for 54. 5%（ 61/112）; involvement of nameless artery accounted for 15. 1 %（ 17/112）. True and false double-chamber imaging 100%（ 112/112）,endometrial calcification translocation accounted for 41. 1%（ 46/112）; the initial entry accounted for 93. 7%（ 105/112）; secondary entry 7. 1%（ 8/112）. Conclusion： 320-slice spiral CT angiography is one of the reliable imaging methods to the diagnosis and clarified classification of AD due to the advantage of rapid and accurate diagnosis.
