Key result
Octogenarians with AAA face higher mortality than septuagenarians, driven primarily by EVAR outcomes.
Why the study?
Optimal management of abdominal aortic aneurysm in elderly patients is not straightforward, necessitating evaluation of treatment outcomes in this population.
Does age ≥80 years compared to 70-79 years worsen survival and complications in patients undergoing treatment for asymptomatic abdominal aortic aneurysm?
Population
283 patients aged 70 years and older with asymptomatic AAA meeting treatment criteria
Comparison
Patients aged 70-79 years vs patients aged 80 years or older undergoing EVAR, OPEN repair, or conservative management
Design
Retrospective cohort study reviewing hospital charts from 2005 to 2012

Higher long-term mortality after EVAR in octogenarians versus septuagenarians warrants age-stratified caution; leaves open optimal treatment selection for asymptomatic AAA in patients ≥80 years.

p-value: p=< 0.01
Long-term mortality after EVAR for asymptomatic abdominal aortic aneurysm is significantly higher in patients aged 80 years and older compared to those aged 70-79 years.
Leur et al. (2015) conducted a cohort in asymptomatic abdominal aortic aneurysm (n=283). Age 80 years or older vs. Age 70-79 years was evaluated on mortality rate (p=< 0.01). Octogenarians with abdominal aortic aneurysm had a significantly higher overall mortality rate than those aged 70-79 years, a difference driven primarily by patients undergoing EVAR (p < 0.01).
