【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。更多还原

【Abstract】 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.更多还原
