Observational retrospective cohort of patients consecutively submitted to elective abdominal aortic aneurysm surgery repair at a tertiary academic referral center from south Europe, between January 2009 and December 2015 through endovascular repair. The exclusion criteria were non-elective cases, aortic intervention due to diagnosis other than infrarenal AAA and complex aortic aneurysms such as juxta-renal, thoraco-abdominal or thoracic aneurysms.

Observational retrospective cohort of patients consecutively submitted to elective abdominal aortic aneurysm surgery repair at a tertiary academic referral center from south Europe, between January 2009 and December 2015 through open repair. The exclusion criteria were non-elective cases, aortic intervention due to diagnosis other than infrarenal AAA and complex aortic aneurysms such as juxta-renal, thoraco-abdominal or thoracic aneurysms.

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.

Acute myocardial infarction (with PCI, CABG or no intervention), decompensated heart failure, neurological deficit (including transient ischemic attack or stroke) or death

Death of any cause

Including digestive complications such as intestinal obstruction or ischemia, acute myocardial infarction (with PCI, CABG or no intervention), decompensated heart failure, neurological deficit (including transient ischemic attack or stroke), respiratory failure (including pneumonia, prolongation of endotracheal intubation, need for a tracheostomy) or acute renal failure (plasma creatinine > 3 mg/dL with or without the need for dialysis).
