摘要
Object. Utilization of covered stent grafts in treating neurovascular disorders has been reported, but their efficacy and safety in vertebral artery (VA) dissecting aneurysms needs further investigation. Methods. Six cases are presented involving VA dissecting aneurysms that were treated by positioning a covered stent graft. Two aneurysms were located distal to the posterior inferior cerebellar artery, and 4 were located proximal to the posterior inferior cerebellar artery. Aspirin as well as ticlopidine or clopidogrel were administered after the procedure to prevent stent-related thrombosis. All patients were followed up both angiographically and clinically. Results. Five of the 6 patients underwent Successful placement of a covered stent graft. The covered stent could not reach the level of the aneurysm in I patient with serious vasospasm who died secondary to severe subarachnoid hemorrhage that occurred 3 days later. Patient follow-Lip ranged from 6 to 14 months (mean 10.4 months), and demonstrated complete stabilization of the obliterated aneurysms, and no obvious intimal hyperplasia. No procedure-related complications such as stenosis or embolization occurred in the 5 patients with successful stent graft placement. Conclusions. Although long-term follow-up studies using a greater number of patients is required for further validation of this technique, this preliminary assessment shows that covered stent graft placement is an efficient, safe, and microinvasive technique, and is a promising tool in treating intracranial VA dissecting aneurysms.
