The impact of weather factors, moon phases, and seasons on abdominal aortic aneurysm rupture.

Background: Several studies have documented that weather factors, seasons of the year, time of the day, and even changes in moon phases have an impact on the occurrence of rupture of an abdominal aortic aneurysm (RAAA); however, the available data are confounding. The objective of this study was to determine the impact of these factors on the prevalence and mortality rate of RAAA.

Methods: This is a retrospective analysis of medical records of patients treated for RAAA over a 10-year period.
