OBJECTIVE: Imaging surveillance after @entity449 repair (EVAR) is critical. In this study we analyzed compliance with imaging surveillance after EVAR and its effect on clinical outcomes. METHODS: Retrospective analysis of prospectively collected data of 565 EVAR @entity1 (August 2001-November 2013), who were followed using duplex ultrasound and/or computed tomography angiography. @entity1 were considered noncompliant (NC) if they did not have any follow-up imaging for 2  years and/or missed their first post-EVAR imaging over 6  months. A Kaplan-Meier analysis was used to compare compliance rates in EVAR @entity1 with @entity135 ( @entity135 ) vs @entity135 ( @entity135 ) anatomy (according to instructions for use). A multivariate analysis was also done to correlate compliance and comorbidities. RESULTS: Forty-three percent were compliant (7% had no follow-up imaging) and 57% were NC. The mean follow-up for compliant @entity1 was 25.4  months (0-119  months) vs 31.4  months for NC (0-140  months). The mean number of imaging was 3.5 for compliant vs 2.6 for NC (P  < .0001). Sixty-four percent were NC for @entity135 @entity1 vs 50% for @entity135 @entity1 (P  = .0007). The rates of compliance at 1, 2, 3, 4, and 5  years for all @entity1 were 78%, 63%, 55%, 45%, and 32%; and 84%, 68%, 61%, 54%, and 40% for @entity135 @entity1 ; and 73%, 57%, 48%, 37%, and 25% for @entity135 @entity1 (P  = .009). The NC rate for @entity1 with late endoleak and/or sac expansion was 58% vs 54% for @entity1 with no endoleak (P  = .51). The NC rate for @entity1 with late reintervention was 70% vs 53% for @entity1 with no reintervention (P  = .1254). Univariate and multivariate analyses showed that @entity1 with @entity3657 had an odds ratio of 1.9 (P  =  .0331), @entity1 with @entity66 had an odds ratio of 2 (P  = .0305), and @entity135 @entity1 had an odds ratio of 1.8 (P  = .0007) for NC. Age and residential locations were not factors in compliance. CONCLUSIONS: Overall, compliance of imaging surveillance after EVAR was low, particularly in @entity135 EVAR @entity1 , and additional studies are needed to determine if strict post-EVAR surveillance is necessary, and its effect on long-term clinical outcome.
