Wingspan stent for high-grade symptomatic vertebrobasilar artery atherosclerotic stenosis.

Purpose: This study was designed to present the treatment outcomes with Wingspan stent angioplasty of high-grade intracranial vertebrobasilar artery (VBA) stenosis in symptomatic patients.

Methods: Between 2007 and 2010, the records of 30 patients with 31 intracranial high-grade VBA stenoses (all ≥ 70%) who underwent elective stenting due to the failure of medical therapy were retrospectively reviewed. Clinical evaluation was performed based on the modified Rankin scale and the National Institutes of Health Stroke Scale.
