Stent treatment of symptomatic intracranial arterial stenosis

Abstract

Objective To investigate the safety, feasibility and efficacy of the Wingspan stent in treatment of symptomatic intracranial arterial stenosis. Methods Wingspan stenting was applied in 90 cases with symptomatic intracranial arterial stenosis. The surgical success rate and periprocedural neurological complications were observed. Digital subtraction angiography was performed at 6 months after stenting to detect the occurrence of restenosis. Results The technical success rate was 98.92% (92/93). Pre⁃treatment stenosis (83.42 ± 9.53)% was improved to (21.82 ± 9.86)% after stent placement. The difference was statistically significant (t = 3.280, P = 0.002). There were 5 patients (5.56%) occurred major periprocedural neurological complications, 3 of them died within 30 days after the procedure. The restenosis rate at 6 months after operation was 19.10% (17/89). Conclusion Symptomatic intracranial arterial stenosis can be treated by Wingspan stenting with high technical success rate. The occurrence of complication is low and short⁃term efficacy is good. However, further study is needed to investigate long⁃ term effect.
