多层螺旋CT血管成像技术在主动脉夹层动脉瘤诊断中的应用价值分析

摘要

Objective To explore the value of multi-slice spiral CT angiography (MSCTA) in the diagnosis of aortic dissecting aneurysms (ADA).Methods 57 cases of ADA in our hospital from April 2013 to October 2016 were selected as research objective,all cases are examined by MSCTA,and the original data were processed by curved planar reconstruction (CPR),multiplanar reformation (MPR),maximum intensity projection (MIP),and shaded surface display (SSD).Analysis of aortic rupture,true and false lumen,intimal flap,the location and extent of aortic dissecting aneurysm,intracavitary thrombosis,and wall calcification were conducted,then compared with diagnosis result of digital subtraction angiography (DSA).Results There were no statistically significant differences in the test results of two kinds of imaging techniques for aortic rupture,true and false lumen,intimal flap,location and scope of aortic dissecting aneurysm,intracavitary thrombosis,wall calcification (P＞0.05),but MSCTA diagnosis had higher accuracy.Conclusion MSCTA can diagnose ADA rapidly,accurately,and safely.It has higher diagnostic value and helps to develop corresponding program timely in clinic,suitable for clinical application.%目的 探讨多层螺旋CT血管成像技术(MSCTA)在主动脉夹层动脉瘤(ADA)诊断中的应用价值.方法 选取本院2013年4月至2016年10月收治的57例患有ADA的患者为研究对象,患者均采用MSCTA进行检查,并将原始数据进行曲面重建(CPR)、多层面重建(MPR)、最大密度投影(MIP)、表面阴影重建(SSD)等技术后处理,分析主动脉破口、真假腔、内膜瓣、主动脉夹层动脉瘤的位置和范围、腔内血栓、管壁钙化等情况,与数字减影血管造影(DSA)诊断进行比较.结果 两种影像技术对主动脉破口、真假腔、内膜瓣、主动脉夹层动脉瘤的位置和范围、腔内血栓、管壁钙化等的检查结果比较,差异无统计学意义(P＞0.05),MSCTA诊断具有较高的准确率.结论 MSCTA能快速、准确、安全的诊断ADA,具有较高的诊断价值,可协助临床上及时制定相应的方案,适合临床推广应用.
