[目的]急性主动脉夹层临床早期诊治困难,应引起临床医生注意。[方法]分析30例急性主动脉夹层病例核磁共振诊断和保守治疗与支架植入术治疗等经验。[结果]急性主动脉夹层病应采取核磁进行诊断,支架植入术治疗,患者恢复较快,效果良好。[结论]患者发病常有高血压病史,并伴劳累、激动等诱因,核磁共振诊断则对急性主动脉夹层病有高度敏感性和特异性。 [Objective] The clinical diagnosis and treatment of acute aortic dissection is difficult and should be paid attention to by clinicians. [Methods] The experience of diagnosis and conservative treatment of 30 cases of acute aortic dissection and stent implantation were analyzed. [Results] The diagnosis of acute aortic dissection should be taken by magnetic resonance imaging (MRI) and stent implantation. The patients recovered quickly and the effect was good. [Conclusions] Patients often have a history of hypertension, accompanied by exertion and agitation. MRI diagnosis is highly sensitive and specific to acute aortic dissection.
