A large proportion of patients with small ruptured abdominal aortic aneurysms are women and have chronic obstructive pulmonary disease.

ABSTRACT: OBJECTIVE:In a population-based cohort of ruptured abdominal aortic aneurysms (rAAAs), our aim was to investigate clinical, morphological and biomechanical features in patients with small rAAAs. METHODS:All patients admitted to an emergency department in Stockholm and Gotland, a region with a population of 2.1 million, between 2009-2013 with a CT-verified rupture (n = 192) were included, and morphological measurements were performed. Patients with small rAAAs, maximal diameter (Dmax) ≤ 60 mm were selected (n = 27), and matched 2:1 by Dmax, sex and age to intact AAA (iAAAs). For these patients, morphology including volume and finite element analysis-derived biomechanics were assessed. RESULTS:The mean Dmax for all rAAAs was 80.8 mm (SD = 18.9 mm), women had smaller Dmax at rupture (73.4 ± 1
