Abstract

Introduction

Various studies have suggested seasonal and monthly atmospheric pressure correlation to Abdominal Aortic Aneurysm (AAA) rupture frequencies. However, such correlation to monthly/seasonal temperature and its alteration has never been studied directly. The objective of this study is to demonstrate whether temperature and its alteration are indeed associated with incidences of infra-renal AAA rupture.

Patients and methods

A total of 50 (n=50) ruptured AAA over a 5-year period were recruited. Local meteorological data on temperature were obtained from UK Meteorological Office.

Results

The p value (<0.1) (Student's t-test) was insignificant for temperature difference (mean=0.58 °C; range, −4.6 to 3.8 °C; 95% CI±°0.72), no correlation was identified between mean monthly/seasonal temperature and mean monthly/seasonal rupture incidence (Pearson) (n=12; r=0.075; p<0.81; rsq=0.0057) (n=4; r=−0.188; p<0.8118; rsq=0.0354).

Conclusion

The findings appear to confirm that temperature alteration on monthly/seasonal basis has no impact on AAA rupture incidences.

温度与腹主动脉瘤破裂:神话还是现实

各种研究表明，季节性和月度大气压力与腹主动脉瘤(AAA)破裂频率相关。然而，这种与月/季节温度及其变化的相关性从未被直接研究过。本研究的目的是证明温度及其改变是否确实与肾下AAA破裂的发生率有关。患者和方法在5年内共招募了50例(n=50) AAA破裂患者。本港气温的气象资料由英国气象局提供。结果温度差异的p值(<0.1)(学生t检验)不显著(平均值=0.58°C;范围，−4.6至3.8°C;95% CI±0.72)，月/季节平均温度与月/季节平均破裂发生率无相关性(Pearson) (n=12;r = 0.075;术中,0.81;rsq = 0.0057) (n = 4;r =−0.188;术中,0.8118;rsq = 0.0354)。结论温度的月度/季节变化对AAA破裂发生率无影响。
