摘　　要：目的研究急性主动脉夹层时间分布规律。方法回顾性研究我院2000年1月2010年12月所有急性主动脉夹层患者的时间资料,分析其月份、季节、周以及时刻分布特点。结果急性主动脉夹层月份分布高峰点为1月4日,高峰段为9月21日~次年4月19日（P〈0.05）;季节分布以冬春季较多（P〈0.05）;周分布无高峰点及高峰段（P〉0.05）;时刻分布高峰点为上午10点及下午4点。结论急性主动脉夹层具有明显的时间分布规律,我们应该在该病的高峰时间更加重视其发生的可能,从而减少误诊,改善预后。Objective To investigate the features of time distribution in the occurrence of acute aortic dissection（AAD）.Methods We retrospectively analyzed all the databases of AAD in our hospital between January 1,2000 and December 31,2010,and studied the monthly,seasonal,weekly,and circadian distribution of the cases.Results In terms of monthly distribution,the occurrence of AAD peaked at January 4th with the high frequency in the period of September 21st to April 19th of the next year（P0.05）.According to the seasonal distribution,the occurrence of AAD peaked in winter and spring（P0.05）.There was no peak time in weekly distribution（P0.05）.In accordance with circadian distribution,the occurrence of AAD peaked at 10 and 16 o＇clock（P0.05）.Conclusion Because of the obvious rhythm of time distribution of AAD,We can pay more attention to the diagnosis of AAD especially in the peak time,thus reducing the mistakes in diagnosis and improving the prognosis.
