Abstract：Objective To analyze the feasibility and safety of endovascular stenting for subacute and chronic vertebrobasilar artery occlusion and its curative effect. Method The clinical data of 18 patients with subacute or chronic vertebrobasilar artery occlusion undergoing endovascular stenting in Renji Hospital from October, 2012 to August, 2016 were analyzed retrospectively, including the perioperative complications, clinical effect, recurrent events during the following-up, pre- and post-operative modified Rankin scale (mRS) scores, Makel scale score and so on. Results Of 18 patients with vertebrobasilar artery occlusion, 16 had recanalization of the occluded arteries and 2 not after the endovascular stenting. Of 16 patients with vertebrobasilar artery recanalization, 6 were improved in the clinical symptoms, 9 had unchanged clinical symptoms and 1 died of intracranial hemorrhage. The following-up 1 year after the operation showed that of 15 patients, 11 were improved in mRS scores and 4 not. Malek scale score was 1 point in 12 patients and 2 points in 3. DSA 1 year after the operation showed that the vertebrobasilar artery had restenosis (stenosis degree>50%) in 1 patient who underwent balloon angioplasty and 14 not. Conclusions Endovascular stenting for the recanalization of symptomatic subacute and chronic vertebrobasilar artery occlusion is technically feasible and safe, and its mid-or long- term curative effect is satisfactory.
