BACKGROUND: Elective repair of large @entity1028 ( @entity1028 ) is associated with the risk of significant perioperative mortality. When @entity439 repair is delayed, @entity1 with asymptomatic large @entity1028 face the risk of death from @entity397 . In addition to the risk of @entity397 , the advancing age of the @entity1 adds a future operative risk. This risk has been historically documented in age groups. However, a more accurate representation of the increasing operative risk with age is needed. METHODS: We analyzed all @entity1 in the American College of Surgeons National Surgical Quality Improvement Program database who underwent endovascular or open repair for asymptomatic infrarenal AAA between 2005 and 2012. Multivariable logistic regression was used to evaluate the effect of increasing age and operative delay on 30-day postoperative mortality. RESULTS: There were 27,576 @entity1 who underwent AAA repair during the study period (mean age 73.5 years, standard deviation 8.6, 80% male, 24% open repair). There was a linear relative increase of 5% (odds ratio [OR] 1.05, 95% confidence interval [CI] 1.04-1.06, P < 0.001) in the odds of @entity204 after AAA repair with each year of operative delay irrespective of treatment approach. There was a linear relative increase of 4% for @entity439 repair (OR 1.04, 95% CI 1.02-1.05, P < 0.001) and 6% for open repair (OR 1.06, 95% CI 1.04-1.08, P < 0.001) with each year of delay in repair. CONCLUSIONS: Because of increasing age, delay in surgery is associated with uniform increase in the risk of perioperative mortality in asymptomatic @entity1 who meet criteria for AAA repair. It is important for surgeons to incorporate this more accurate estimation of operative risk into discussions with @entity1 who qualify for treatment yet decide to forgo surgery for the repair of their AAA.
