The aim of this study is to understand Patients who undergo endovascular aneurysm repair (EVAR) often require reintervention after the index repair. The long-term rate of reintervention and how this has changed with newer device technology are poorly understood. Therefore, we performed a systematic review and meta-analysis of the available literature to determine long-term freedom from reintervention after EVAR and the change in reintervention rates over time.

We performed a systematic review of MEDLINE, Embase, Cochrane Library, and in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We included randomized controlled trials and observational studies that documented the rate of reintervention after EVAR. We performed a meta-analysis of Kaplan-Meier freedom from reintervention each year after EVAR. We used linear regression to evaluate change in reintervention rate over time with newer device technology.

We included a total of 30 studies (randomized trials, n = 3; observational studies, n = 27) comprising 32,126 patients in this review and meta-analysis. Studies ranged in the implantation date of the EVAR device from 1996 to 2014.
