Open Versus Endovascular Repair of Abdominal Aortic Aneurysms

Retrospective Cohort Study of Open Versus Endovascular Repair of Abdominal Aortic Aneurysms

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.

Inclusion Criteria:

• This is an observational retrospective cohort study of all patients consecutively submitted to elective AAA surgery repair at a tertiary academic referral center from south Europe, between January 2009 and December 2015.

Exclusion Criteria:

• 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.
