摘要 目的探讨多排螺旋CT与MRA在主动脉夹层诊断中应用分析。方法 189例主动脉夹层患者均经手术或血管造影证实,观察采用多排螺旋CT血管成像(MSCTA)与磁共振血管成像(MRA)、经胸超声心动图(TTE)检查诊断符合率。结果本组病例经多排螺旋CT血管成像(MSCTA)与磁共振血管成像(MRA)、经胸超声心动图(TTE)检查其中DebakeyI型68例,DebakeyⅡ型22例,DebakeyIlI型99例,多排螺旋CT血管成像(MSCTA)与磁共振血管成像(MRA)诊断主动脉夹层与手术或血管造影证实进行比较符合率100%。结论应用多排螺旋CT血管成像与磁共振血管成像对主动脉夹层能够明确诊断;多排螺旋CT血管成像避免了磁共振血管成像扫描时间长的缺点,并且降低了血流动力学不稳定患者的风险度;多排螺旋CT血管成像是主动脉夹层的一种安全、快速、无创、有效的诊断方法。 Objective To evaluate the application of multi-slice spiral CT and MRA in the diagnosis of aortic dissection.Methods 189 patients of aortic dissection were confirmed by surgery or angiography,the coincidence rate of diagnosis were observed using multi-slice spiral CT angiography(MSCTA),magnetic resonance angiography(MRA)and transthoracic echocardiography(TTE).Results 68 cases of Debakey I type,22 cases of Debakey Ⅱ type,99 cases of Debakey IlI type were confirmed by multi-slice spiral CT angiography(MCTA),magnetic resonance angiography(MRA)and transthoracic echocardiography(TTE),in which multi-slice spiral CT angiography(MSCTA)and magnetic resonance angiography(MRA)diagnosis of aortic dissection and confirmed by surgery or angiography were more in line with rate of 100%.Conclusion Aortic dissection can be confirmed by multi-slice spiral CT or magnetic resonance angiography.Compered with magnetic resonance angiography,multi-slice spiral CT angiography has the short scanning time,and it can reduce the risk of patients with hemodynamic instability.Multi-slice spiral CT angiography in aortic dissection is a safe,rapid,noninvasive and effective diagnostic method.
