The aim of this paper was to determine whether weather factors including atmospheric pressure are associated with the occurrence of ruptured abdominal aortic aneurysm (RAAA). We investigated our institutional experiences of RAAA in more than 150 patients during 8 years. Further, we performed a meta-analysis of published studies reporting the influence of atmospheric pressure on RAAA. We retrospectively evaluated 152 patients who underwent surgery for RAAA (including ruptured iliac arterial aneurysm) at our institute between 1 January 2006 and 31 December 2013. Daily regional meteorological data (in the nearest weather station located 3.5 km from the hospital) were obtained online from Japan Meteorological Agency. To identify comparative studies of mean atmospheric pressure on the day with RAAA versus that on the day without RAAA, MEDLINE and EMBASE were searched through January 2014 using Web-based search engines (PubMed and OVID). Mean sea level atmospheric pressure, delta mean atmospheric pressure (difference between mean sea level atmospheric pressure on the day and that on the previous day), and sunshine duration on the day with RAAA were significantly lower than those on the day without RAAA: 1012.43±7.44 versus 1013.71±6.49 hPa, P=0.039, -1.18±5.15 versus 0.05±5.62 hPa, P=0.005; and 4.76±3.76 versus 5.47±3.88 h, P=0.026; respectively. A pooled analysis of 8 studies (including our institutional study) demonstrated that mean atmospheric pressure on the day with RAAA was significantly lower than that on the day without RAAA: standardized mean difference, -0.09; 95% confidence interval, -0.14 to -0.04; P=0.0009. Atmospheric pressure on the day with RAAA appears lower than that on the day without RAAA. Atmospheric pressure may be associated with the occurrence of RAAA.
本文旨在确定包括大气压力在内的天气因素是否与腹主动脉瘤破裂（RAAA）的发生有关。我们调查了本机构在8年多时间里150多名RAAA患者的情况。此外，我们对已发表的关于大气压力对RAAA影响的研究进行了荟萃分析。我们回顾性评估了2006年1月1日至2013年12月31日期间在本机构接受RAAA（包括髂动脉瘤破裂）手术的152例患者。每日区域气象数据（来自距离医院3.5公里的最近气象站）从日本气象厅在线获取。为了确定RAAA发生日与非RAAA发生日平均大气压力的比较研究，使用基于网络的搜索引擎（PubMed和OVID）在2014年1月前对MEDLINE和EMBASE进行了检索。RAAA发生日的平均海平面大气压力、平均大气压力差值（当天与前一天平均海平面大气压力之差）和日照时长显著低于非RAAA发生日：分别为1012.43±7.44与1013.71±6.49百帕，P = 0.039；-1.18±5.15与0.05±5.62百帕，P = 其005；以及4.76±3.76与5.47±3.88小时，P = 0.026。对8项研究（包括我们机构的研究）的汇总分析表明，RAAA发生日的平均大气压力显著低于非RAAA发生日：标准化平均差值为-0.09；95%置信区间为-0.14至-0.04；P = 0.0009。RAAA发生日的大气压力似乎低于非RAAA发生日。大气压力可能与RAAA的发生有关。
