Objective: Fusiform intracranial aneurysms are non-saccular, spindle-shaped aneurysms which are defined as a circumferantial dilation of an artery without the presence of a distinct neck. Fusiform aneurysms have unfavourable outcomes with a mortality rate of 30% and a rupture risk of 3% per year if left untreated. The aim of this study is to present a single -center’s experience in Noth-Western Greece with the use of flow diverters for the treatment of fusiform intracranial aneurysms and provide evidence of the efficacy and safety of this neurovascular procedure.
Methods: We analyzed retrospectively 3 patients with unruptured fusiform intracranial aneurysms treated with flow-diverter stents. Occlusion rates, neurologic morbidity/mortality, and other clinical variables were analyzed.
Results: Three patients with three fusiform aneurysms were treated with a flow diverter stents. One aneurysm was located in the internal carotid artery, one in the right middle cerebral artery and one in the right vertebral artery. Angiographic and clinical follow-up was available for all aneurysms 12 months after embolization. All three aneurysms have been completely occluded. Slight hemiparesis due to post-embolization ischemic stroke occurred in one patient who recovered completely. Neurologic mortality rate was 0%.
Conclusion: Based on our clinical experience, endovascular treatment with flow diverter stents seems to be a feasible and efficient treatment option for unruptured fusiform brain aneurysms. Further studies with larger cohorts should be performed in order to evaluate the safety and efficacy of this method.
