Background/Objective Endovascular aneurysm embolization is effective and safe. However, the angiographic recurrence continues to be an issue after endovascular embolization. In this study, we aimed to report the rate of recurrence at 1-year follow up angiography and to investigate the predictors of recurrence. Methods We used the SMART registry to identify subgroup of patients who underwent endovascular embolization with SMART coils and had one year follow up angiography. The primary outcome of

Results A total of 466 patients were included of whom 78 (16%) had recurrence at 1 year follow up angiography. Mean age was 60 years and 74% were female. 112 (24%) of treated aneurysms were ruptured and 125 (27%) were 4 mm in size. On Multivariate analysis, Immediate post procedure Raymond II and III (vs Raymond I), neck size 4 (vs.<4), stentassisted coiling, and age were associated with the risk of recurrence at one-year follow-up.
