摘　　要：目的:探讨急性主动脉夹层早期CTA诊断价值。方法:回顾性分析2016年1月至2018年1月期间于新疆医科大学第一附属医院诊治的主动脉夹层动脉瘤患者152例,对所有患者实施MSCT扫描,并进行MPR、MIP、VRT等处理。结果:按照DeBakey分型,Ⅰ型67例,Ⅱ型9例,Ⅲ型86例,共显示破口166处,141例患者显示单个破口,8例患者显示多个破口;119例显示真假腔和主动脉夹层内膜瓣,其中18例显示内膜移位的特征,26例显示主动脉扩张、各段管径不一致的特征,双侧胸腔积液64例,心包积液31例;97例患者存在分支血管受累:肝总动脉受累21例,头臂干受累者17例,肾动脉受累者31例,左锁骨下动脉受累24例,肠系膜上动脉受累者4例。结论:多层螺旋CTA扫描是诊断急性主动脉夹层首选检查方法,可以提供较为准确的临床分型和分支受累情况,可以在临床上作进一步推广。Objective:To explore the diagnostic value of early CTA in acute aortic dissection.Methods:Retrospective analysis from January 2016 to January 2018 during the period of diagnosis and treatment of 152 patients with aortic dissection aneurysm,implement multislice CT scan for all patients,and multiplanar reconstruction(MPR),maximum density projection(MIP)and volume reconstruction(VRT),and other processing.Results:According to DeBakey typing,typeⅠ67,typeⅡ9 cases,typeⅢ86 cases,a total of 166 cases,141 patients showed single fracture,8 patients showed multiple fractures;119 cases showed the true and false cavity and aortic dissection intimal flap,including 18 cases showed characteristics of shifting the endometrium,26 cases showed aortic expansion,paragraphs diameter,the characteristics of the inconsistent bilateral pleural effusion in 64 cases,31 cases of pericardial effusion;97 patients exist branch vascular involvement,common hepatic artery involvement 21 cases,dry head arm involvement of 17 cases,31 cases of renal artery involvement,left subclavian artery involvement 24 cases,4 cases of superior mesenteric artery involvement.Conclusion:Multilayer helical CTA scan is the preferred method for diagnosis of acute aortic dissection,which can provide more accurate clinical typing and branch involvement,and can be further promoted clinically.
