Small case series have been reported in the literature but few studies with a large number of patients have been published. We present our experience with the SFD for the treatment of intracranial aneurysms in Canada.Methods Centers across Canada using SFDs were contacted to fill out a case report form for patients treated with an SFD 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 patients were treated with SFDs in eight centers in Canada between January 2009 and August 2013. The aneurysms were located in the posterior circulation in 16 patients and in the anterior circulation in 76 patients. Most aneurysms (75\%) were saccular in shape; 22\% were fusiform and 3\% were blister aneurysms. The size of the aneurysms 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 aneurysms were either completely or near-completely occluded. The rate of complications was higher for fusiform aneurysms (p\<0.001).Conclusions The SFD appears to be an important tool for the treatment of complex intracranial aneurysms. 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.}, issn = {1759-8478}, URL = {https://jnis.bmj.com/content/8/3/273}, eprint = {https://jnis.bmj.com/content/8/3/273.full.pdf}, journal = {Journal of NeuroInterventional Surgery} }
