Objective: To examine the hypothesis of seasonal variation in the rupture of abdominal aortic aneurysm in our region.
Design: Retrospective open study.

Patients: Forty-six patients with abdominal aortic aneurysm admitted between 1991-1995.
Intervention: The month of admission was registered.

Results: The majority of ruptures (78%) occurred during the months October and April, a phenomenon proven to be periodical (p<0.05).
Conclusions: The abdominal aortic aneurysm rupture clearly showed seasonal variation.
