Number of EVAR cases, ratio of EVAR/open aneurysm repair (OAR), major clinical outcomes, and discharge status were analyzed by decade. Interval data were compared with analysis of variance (ANOVA) and proportions via chi-squared tests.Abstract: RESULTS: A total of 174,714 AAA repairs (124,869 EVARs) were identified. The ratio of EVAR/OAR increased with increasing age. Between 2005 and 2009, the total number of AAA repairs increased by 21% (7,179 vs. 8,554) and EVARs increased by 50% (5,057 vs. 7,650; P < 0.05) in patients older than 80 years. In 2009, 85% of AAA repairs in patients older than 80 years were EVARs. Patients older than 80 years constituted 25% of the total EVAR cohort. Although the in-hospital mortality rate remained acceptable in all age groups, EVAR-associated mortality, length of stay, and discharge to a skilled nursing facility increased with each successive decade of life (P < 0.05). Rates of postoperative myocardial infarction and acute renal failure also increased with increasing age (P < 0.05). EVAR results are presented by decade.Abstract: CONCLUSIONS: EVAR is being performed with increasing frequency in patients older than 80 years, with one-quarter of EVAR performed in patients aged 80 years and older in the current sample. Although mortality rates remain acceptable in this elderly population, EVAR and OAR are associated with an age-dependent increase in death, complications, and discharge to extended care facilities. These factors, in addition to long-term risk of aneurysm rupture, should be considered when evaluating the appropriateness of elective aneurysm repair in the elderly.Copyright � 2014 Elsevier Inc.
