目的:分析无痛性急性主动脉夹层患者的临床特点,探讨如何提高无痛性急性主动脉夹层的诊断率及降低死亡率。方法:收集2004-2011年在武汉同济医院住院的急性主动脉夹层患者共625例,其中无痛性39例,对其临床特点进行回顾性研究。结果:无痛性夹层患者从发病到住院的时间、住院后到确认的时间均明显长于痛性主动脉夹层患者,死亡率也较痛性主动脉夹层患者高;常规心脏彩超对无痛性主动脉夹层的确诊率达到74.19%。结论:了解无痛性主动脉夹层的临床表现,有效结合彩色多普勒超声、CT等影像学检查,早期诊治是降低无痛性夹层患者死亡率的关键。
Objective: To analyze the clinical features of patients with painless acute aortic dissection and to explore ways to improve the diagnostic rate and reduce the mortality rate of painless acute aortic dissection. Methods: A total of 625 patients with acute aortic dissection who were hospitalized in Wuhan Tongji Hospital from 2004 to 2011 were recruited. Among them, 39 cases were painless and their clinical features were retrospectively studied. Results: The time between onset and hospitalization of patients with painless dissection was significantly longer than that of patients with painful aortic dissection after hospitalization, and the mortality rate was also higher than that of patients with painful aortic dissection. Conventional echocardiography had no effect on painless patients The diagnosis rate of arterial dissection reached 74.19%. Conclusion: To understand the clinical manifestations of painless aortic dissection and effectively combine the imaging findings such as color Doppler ultrasound and CT, early diagnosis and treatment are the keys to reduce the mortality of patients with painless dissection.
