Background Ruptured abdominal aortic aneurysm (RAAA) presents with increased frequency in the winter and spring months. Seasonal changes in atmospheric pressure mirrors this pattern.Aim To establish if there was a seasonal variation in the occurrence of RAAA and to determine if there was any association with atmospheric pressure changes.Methods A retrospective cohort-based study was performed. Daily atmospheric pressure readings for the region were obtained.Results There was a statistically significant monthly variation in RAAA presentation with 107 cases (52.5%) occurring from November to March. The monthly number of RAAA and the mean atmospheric pressure in the previous month were inversely related (r = 0.752, r(2) = 0.566, P = 0.03), and there was significantly greater daily atmospheric pressure variability on days when patients with RAAA were admitted.Conclusion These findings suggest a relationship between atmospheric pressure and RAAA.
