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，DeBakey Ⅰ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, DeBakey 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.
