INTRODUCTION: The @entity450 ( @entity450 ) is used for the treatment of @entity438 . Small case series have been reported in the literature but few studies with a large number of @entity1 have been published. We present our experience with the @entity450 for the treatment of @entity438 in Canada. METHODS: Centers across Canada using SFDs were contacted to fill out a case report form for @entity1 treated with an @entity450 in their center. Individual centers were responsible for approval from their ethics committee. Image analysis was performed by individual operators. The case report forms were collected and the final analysis was performed. RESULTS: A total of 92 @entity1 were treated with SFDs in eight centers in Canada between January 2009 and August 2013. The @entity439 were located in the posterior circulation in 16 @entity1 and in the anterior circulation in 76 @entity1 . Most @entity439 (75%) were saccular in shape; 22% were fusiform and 3% were @entity439 . The size of the @entity439 varied from 2 to 60   mm with the neck varying from 2 to 60   mm. Perioperative morbidity and mortality were 8.7% and 2.2%, respectively. At the last available follow-up, 83.1% of the @entity439 were either completely or near-completely occluded. The rate of complications was higher for @entity439 (p<0.001). CONCLUSIONS: The @entity450 appears to be an important tool for the treatment of @entity438 . Treatment outcomes and complication rates remain a problem, but should be considered in the context of available alternative interventions. Ongoing analysis of flow-diverting stents for radiographic and clinical performance is required.
