Treatment of symptomatic vertebrobasilar artery stenosis with stent-assistant angioplasty in the elderly

ABSTRACT

OBJECTIVE: To study the efficacy, safety, and feasibility of stent-assistant angioplasty (SAA) in the treatment of symptomatic vertebrobasilar artery stenosis in the elderly. METHODS: SAA was performed in 26 elderly patients with symptomatic vertebrobasilar artery stenosis. The success rate, perioperative complications, and long-term effectiveness were evaluated. RESULTS: A total of 29 balloon expandable stents were implanted in these patients. The success ratio was 100%. The degree of stenosis decreased from 81.3 ± 8.8% to 3.7 ± 3.6% (p < 0.01). Complications were absent during the perioperative period. Follow-up was performed for seven to 36 months (median 21.9 months). Two patients developed the recurrent symptoms of vertebrobasilar artery stenosis, and no cerebral ischemic events were noted in the remaining patients, suggesting a favorable outcome. CONCLUSION: SAA is a safe and effective strategy for the treatment of symptomatic vertebrobasilar artery stenosis in the elderly.
