    Abstract:

    Endovascular aneurysm repair (EVAR) is an increasingly used alternative to open surgical repair of unruptured abdominal aortic aneurysms (AAAs). The effect of EVAR on postprocedure acute renal failure has not been determined. We hypothesized that EVAR would be associated with a lower risk of acute renal failure and acute renal failure requiring hemodialysis.A retrospective cohort study was conducted of the 2002 Nationwide Inpatient Sample, the largest all-payer inpatient care database in the United States, reflecting discharges from a representative sample of United States hospitals. We identified 6614 discharges with a primary diagnosis of unruptured AAA and a primary procedure code for open AAA repair or EVAR. We excluded 56 patients with end-stage renal disease and 42 patients who underwent concomitant aortorenal bypass. We compared EVAR vs open repair in this cohort. The main outcome measures were acute renal failure and acute renal failure requiring dialysis.A total of 6516 patient discharges met the inclusion criteria for the study, and postprocedure acute renal failure developed in 439 (6.7%). EVAR was associated with lower odds of acute renal failure (adjusted odds ratio, 0.42; 95% confidence interval, 0.33 to 0.53) and acute renal failure requiring dialysis (adjusted odds ratio, 0.30, 95% confidence interval, 0.15 to 0.63). Results were similar when EVAR and open AAA repair were compared within quintiles of the propensity score for the receipt of EVAR.Compared with open AAA repair, EVAR is associated with a lower risk of postprocedure acute renal failure.
