Clinical study on the treatment of symptomatic intracranial arterial stenosis with Apollo stent

Abstract

Objective To explore the safety and effect of angioplasty with Apollo stent for symptomatic intracranial arterial stenosis. Methods Twenty⁃two symptomatic intracranial arterial stenosis patients (24 arteries) underwent Apollo stent placement. The follow⁃up period was 3-28 months (average 14 months). Successful rate, perioperative complications, pre ⁃ and post ⁃ operative National Institute of Health Stroke Scale (NIHSS), in⁃sent restenosis (ISR), stroke recurrence and case⁃fatality rate were asessed. Results Procedural and clinical success was achieved in 22 (91.67% ) target vessels. The degree of stenosis was reduced from the baseline of (73.23 ± 9.59)% to (4.12 ± 9.17)% after stenting (t = 3.325, P = 0.005). No perioperative complications occurred. Neural function was improved (NIHSS score: postoperation, 0.59 ± 1.35 vs. preoperation, 0.59 ± 1.74; t = 2.718, P = 0.015). No in⁃stent restenosis was seen by CT angiography (CTA). No patients had stroke recurrence or died. Conclusion Angioplasty and stenting with Apollo stent for treating symptomatic intracranial arterial stenosis is safe and effective.
