BACKGROUND AND PURPOSE: We sought to assess the long-term outcome and efficacy of percutaneous transluminal angioplasty in the treatment of symptomatic intracranial atherosclerotic stenoses.
METHODS: Twenty-three patients with fixed symptomatic intracranial stenoses were treated over a 5-year period with percutaneous transluminal angioplasty. Patients who underwent successful angioplasty were followed up for 16 to 74 months (mean, 35.4 months).
RESULTS: An angioplasty that resulted in decreased stenosis was performed in 21 of 23 patients (91.3%). In 1 case a stenosis could not be safely crossed, and in another balloon dilatation resulted in vessel rupture. This vessel rupture resulted in the 1 periprocedural death in the series. In follow-up there was 1 stroke in the same vascular territory as the angioplasty and 2 strokes in the series overall. This yielded an annual stroke rate of 3.2% for strokes in the territory appropriate to the site of angioplasty.
CONCLUSIONS: Intracranial angioplasty can be performed with a high degree of technical success. The long-term clinical follow-up available in this series suggests that it may reduce the risk of future stroke in patients with symptomatic intracranial stenoses.
