This is an observational retrospective cohort study of all patients consecutively submitted to elective abdominal aortic aneurysm surgery repair at a tertiary referral centre between 2009 and 2015. Patients were excluded if they were non-elective cases or had complex aortic aneurysms (juxta-renal, thoraco-abdominal or thoracic). Differences between both groups of repair were assessed, as well as short- and long-term complications including medical complications, duration of hospital stay, major cardiovascular events, mortality and vascular reintervention.

In open surgery repair group, aneurysm repair was performed by open surgery including aortobifemoral bypass, aorto-bi-iliac bypass and tubular aortic bypass. In endovascular repair (EVAR group), aneurysm correction was performed by percutaneous approach, femoral cutdowns and aorto-uni-iliac EVARs with femorofemoral bypass.
