Basilar artery stent angioplasty for symptomatic intracranial athero-occlusive disease: complications and late midterm clinical outcomes.

Abstract

Despite a significant incidence of ischemic and nonischemic complications after basilar artery stent placement, most patients in this small series achieved freedom from vertebrobasilar ischemia and good to excellent clinical outcomes at late midterm follow-up (12-46 months). Ischemic complications usually had an early delayed presentation and procedural risks correlated with lesion characteristics.
