This study assessed the proportion of previously known abdominal aortic aneurysm (AAA) in patients presenting with a ruptured AAA (rAAA) and analyzed the reasons for nontreatment at the time of the initial AAA diagnosis.
This retrospective, observational study included all patients with rAAA admitted to a hospital in the counties of Stockholm and Gotland during 2009 to 2013.
