摘要
目的分析64层螺旋CT主动脉成像应用于主动脉夹层中的诊断价值。方法选取2015年1月-2016年4月期间,我院接收的连续性主动脉夹层患者30例,均采用64层螺旋CT主动成像技术进行临床诊断,并对诊断中得到的全部数据进行MPR、MRP以及VRT重建分析。结果 CT主动脉成像结果显示,30例患者均有明显的撕裂内膜片与真假腔,且动脉期真腔的平均CT值明显高于假腔高(P<0.05);30例患者的初始破口位置均得到明确,其中24例患者例显示为一个或者多个再破口,2例患者无再破口显示;其中22例III型患者的初始破口位置处于主动脉弓降部位或者是降胸主动脉附近端,且扫描图像均显示出了全部患者的主动脉重要分支受累与假腔中的血栓形成等情况。结论 64层螺旋CT主动脉成像技术,拥有快速、无创以及准确度较高等多种特点,在主动脉夹层临床诊断中效果显著,值得进一步推广与使用。
Objective To investigate the diagnostic value of 64-slice spiral CT aortic angiography in aortic dissection. Methods A total of 30 patients with consecutive aortic dissection who were admitted to our hospital from January 2015 to April 2016 were enrolled. The 64-slice spiral CT aortic angiography was used for clinical diagnosis in all patients, and MPR, MRP, and VRT reconstruction was performed for all data during diagnosis. Results The CT aortic angiography showed that 30 patients had significant intimal tear and true and false lumens, and in the arterial phase, the true lumen had a significantly higher mean CT value than the false lumen（P〈0.05）; the position of initial opening was identified in 30 patients, among whom 24 type III patients had an initial opening in the descending part of the aortic arch or in the proximal end of the thoracic aorta. The scan images showed involvement of the major branch of the aorta and thrombosis in the false lumen in all patients. Conclusion The 64-slice spiral CT aortic angiography is a fast, noninvasive, and highly accurate technique and has an excellent effect in the clinical diagnosis of aortic dissection,and therefore, it holds promise for clinical application.
