摘要
目的探讨主动脉夹层的CT表现及其临床意义。方法对近年来我院收治25例主动脉夹层患者的16层螺旋CT平扫及血管造影扫描(CTA)的临床资料进行回顾性分析。结果本组25例主动脉夹层A型11例,B型14例;经螺旋CT平扫观察到7例出现主动脉直径增大,钙化内膜片内移7例,胸腔以及心包积液7例、新鲜血栓4例;CTA图像观察到内膜破口24例,CTA下内膜突破口显示率为96.00%(24/25),显示内膜片为24例,显示率为96.00%(24/25),显示真假腔25例,显示率达100%(25/25)。结论 16层螺旋CT对主动脉夹层的临床诊断具有较高的价值,应在临床诊断中加以推广并应用。
Objective To explore the CT manifestations of aortic dissection and its clinical significance. Methods The clinical data of 25 cases of patients with aortic dissection by using 16-slice spiral CT scan and angiography scan （CTA） were retrospectively analyzed in recent years in our hospital. Results 11 cases of aortic dissection type A in 25 eases,B type in 14 eases;7 cases of aortic diameter increases was observed by spiral CT scan,calcified intimal flap shift occurred in 7 cases,7 cases of pleural and pericardial effusion,4 cases of fresh thrombus. 24 cases of intimal tears was observed by CTA images,the detection rate of intimal breakthrough under CTA display was 96.00%（24/25）,24 cases of intimal,and display rate was 96.00% （24/25）,the true and false lumen in 25 cases,the display rate of 100% （25/25）. Conclusion 16-slice spiral CT in the diagnosis of aortic dissection has a high value in clinical diagnosis,should be promoted and applied in clinical diagnosis.
