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 investigate the application of multislice spiral CT and MRA in the diagnosis of aortic dissection. Methods A total of 189 patients with aortic dissection were confirmed by surgery or angiography. The coincidence rates of MSCTA, MRA and TTE were observed. Results In this group of patients, 68 cases of DebakeyI type, 22 cases of Debakey type Ⅱ and 99 cases of DebakeyIlI type were examined by multi-slice spiral CT angiography (MSCTA) and magnetic resonance angiography (MRA) and transthoracic echocardiography (TTE) Spiral CT angiography (MSCTA) and magnetic resonance angiography (MRA) diagnosis of aortic dissection and surgery or angiography confirmed in line with the rate of 100%. Conclusion Multi-detector CT angiography and magnetic resonance angiography can make a definite diagnosis of aortic dissection. Multislice spiral CT angiography can avoid the shortcomings of long time magnetic resonance angiography scanning and reduce the risk of hemodynamic instability Risk; Multi-slice spiral CT angiography is a safe, rapid, noninvasive and effective diagnostic method of aortic dissection.
