A systematic review on outcome after stenting for intracranial atherosclerosis
Angioplasty and stenting is increasingly being used for the treatment of intracranial stenoses. Based on a literature search (01/1998 to 04/2008) we sought to determine the immediate and long-term outcomes, as well as the durability of this procedure.

We identified 31 studies dealing with 1177 procedures, which had mainly been performed in patients with a symptomatic (98%) intracranial high-grade stenosis (mean: 78+/-7%) at high technical success rates (median: 96%; interquartile range [IQR]: 90% to 100%). The periprocedural minor or major stroke and death rates ranged from 0% to 50% with a median of 7.7% (IQR: 4.4% to 14.3%). Periprocedural complications were significantly higher in the posterior versus the anterior circulation (12.1%, versus 6.6%, P50% occurred more frequently after the use of a self-expandable stent (16/92; 17.4%, mean follow-up time: 5.4 months) than a balloon-mounted stent (61/443; 13.8%, mean follow-up time: 8.7 months; P |
