Abstract

Objectives: This study aims to evaluate the effectiveness and share some of our experiences treating intracranial vertebral artery fusiform aneurysms (IVAFA) using flow diverting stents (FDS). Subjects and methods: Retrospective study on 10 patients with IVAFA treated with FDS at Viet Duc University Hospital from January 2020 to December 2022, with a minimum follow-up time of 6 months. Clinical features, images, and data on the procedure and outcomes were collected. Results: A total of 10 patients (9 male, 1 female, with a mean age of 48.9 ± 6.5 years) were included in the study. All patients were treated using a single stent. Complete occlusion was achieved in all patients after 6 months, and significantly improved symptoms compared with before intervention. The mean mRs score before the intervention was 1.2 points compared to 1.1 after. Major complications occurred in 2 patients (1 case died from an intracerebral hemorrhage related to antiplatelet drugs, 1 case of cerebral infarction due to occlusion of bilateral posterior inferior cerebellar artery). Minor complications were observed in 2 patients (1 asymptomatic stent occlusion and 1 asymptomatic post-stent vertebral artery stenosis). Conclusion: Flow diversion is an effective method in treating IVAFA, but there is always potential for early or late acute complications, so there must be adherence to diligent patient selection and procedural and periprocedural nuances.
