Ruptured abdominal aortic aneurysm (RAAA) is a highly mortal entity. In recent years, the role of seasonality has been proposed in the incidence of RAAA. In this study, we sought possible correlations between monthly atmospheric pressures and the number of patients admitted with RAAA.
Twenty-four patients who were admitted to our Trauma and Emergency Surgery Department with a diagnosis of RAAA from January 1995 to May 2003 were retrospectively evaluated. Data were collected from patient records, admission charts, hospital death certificate registry, and operating-room records. Only patients whose diagnosis of RAAA was confirmed during surgery were included. Atmospheric pressure records of Istanbul for individual months covering the study period were obtained from the Meteorology Office. The incidences of RAAA and the mean monthly atmospheric pressures were compared.
Most of the patients were admitted in winter months. Admissions culminated in January with six patients, at which time the mean atmospheric pressure was 765.5 mmHg. There were no admissions in May, during which the mean atmospheric pressure was 760.8 mmHg. The distribution of monthly admissions for RAAA was not statistically significant (p>0.05). The mean atmospheric pressures tended to run a higher course before the months in which increased admissions were seen.
Our findings do not corroborate the presence of a relationship between the incidence of RAAA and the atmospheric pressure.
腹主动脉瘤破裂（RAAA）是一种致死率很高的疾病。近年来，有人提出季节性因素在RAAA发病率中起作用。在本研究中，我们探寻每月大气压力与RAAA入院患者数量之间可能存在的相关性。
回顾性评估了1995年1月至2003年5月间因RAAA诊断入住我院创伤与急诊外科的24例患者。数据收集自患者病历、入院记录、医院死亡证明登记处和手术室记录。仅纳入手术中确诊为RAAA的患者。研究期间伊斯坦布尔各月的大气压力记录来自气象局。比较了RAAA的发病率和月平均大气压力。
大多数患者在冬季入院。1月份入院人数最多，有6例患者，此时平均大气压力为765.5 mmHg。5月份无入院患者，该月平均大气压力为760.8 mmHg。RAAA每月入院人数的分布无统计学意义（p>0.05）。在入院人数增加的月份之前，平均大气压力往往呈上升趋势。
我们的研究结果并未证实RAAA发病率与大气压力之间存在关联。
