摘　　要：【目的】探讨主动脉夹层（AD）的临床特点和各种影像学特征。【方法】收集53例AD患者的临床及各种影像学资料，分析其临床特点和影像学特征。【结果】AD主要病因是高血压（77．3％），表现为突发胸、背、腰腹撕裂样疼痛等典型症状（48例，90．6％），血压升高伴休克貌，四肢血压脉搏不对称，部分患者以并发症为首发症状；超声心动图（TTE）、CT血管造影（CTA）、MRI确诊率分别为75％、100％、92．9％。【结论】AD临床表现复杂，CTA是临床急诊诊断AD的首选方法，掌握临床特点早期诊断和合理治疗是改善患者预后的关键。[Objective] To explore the clinical characteristics and imaging findings of aortic dissection （AD）. [Methods] The clinical data and imaging data in 53 AD patients were collected, and their clinical char- acteristics and imaging findings were analyzed. [Results]The major cause of AD was hypertension （77.4 %）. The typical symptoms were tearing pain involvement of chest, back, waist and abdomen in 48 patients （90.6 %）. The patients presented high blood pressure accompanying with shock appearance. The initial symp- toms of some patients were complications such as inconsistent blood pressure and pulse of extremities. The di- agnostic accuracy of echocardiography （TTE）, CT angiography （CTA） and MRI were 75%, 100% and 92.9%, respectively. [Conclusion] The clinical manifestations of AD are complex. CTA may be the first choice method of the emergency diagnosis of AD. Grasping the clinical characteristics, early diagnosis and the rational therapy is the key of improving the prognosis.
