Objective: The effect of suprarenal fixation (SR) compared with infrarenal fixation (IR) on renal function during endovascular aneurysm repair (EVAR) remains controversial. This study aims to compare the renal outcomes between fixation types in short- and long-term follow-up. Methods: Patients undergoing EVAR for infrarenal abdominal aortic aneurysm between 2005 and 2013 were included. The estimated glomerular filtration rate (eGFR) was measured at baseline and during a follow-up of 5 years. A decline in renal function was defined as a 20% or greater decrease in the eGFR. Changes in the eGFR were compared between SR and IR groups at 1 to 7 days, 30 days, and 1 to 5 years postoperatively. Preoperative renal insufficiency was defined as an eGFR of less than 60 mL/min/1.73 m2, and those patients were included in the subanalyses. Results: A total of 358 patients were included. Among these, 267 (74.6%) had SR and 91 (25.4%) had IR fixation. A decrease in renal function occurred more commonly after SR than after IR in 1 to 7 days postoperatively (P =.009), but no difference was noticed at 30 days and 1 to 5 years. Regardless of the fixation method, renal function steadily decreased steadily over time after EVAR (estimate –3.13 per a year; 95% confidence interval, –3.40 to –2.85; P <.001). Patients with preexisting renal insufficiency were included in subgroup analyses, and those with SR were more often found to have a decline in eGFR 5 years postoperatively than their counterparts with IR (59.5% vs 20.0%; P =.036). Conclusions: An immediate postoperative decrease in renal function was seen more often after SR fixation than IR fixation but this difference was transient. SR fixation is a safe method for patients with normal renal function. Long-term results seems to favor IR over SR in patients with preexisting renal insufficiency.
