Long-term follow-up results of stenting angioplasty for elderly patients with severe symptomatic intracranial vertebral artery atherosclerotic stenosis
Abstract：Objective To assess the safety and efficacy of stenting angioplasty for elderly patients with severe symptomatic intracranial vertebral artery atherosclerotic stenosis during the long-term follow-up period.Methods Forty elderly patients with severe symptomatic intracranial vertebral artery atherosclerotic stenosis admitted to our hospital for stenting angioplasty were included in this study.Six months after they underwent multimodality imaging-guided stenting angioplasty,the instent restenosis was detected by DSA.The patients were followed up,during which perioperative ischemic stroke or death,receurrent ischemic stroke and stent restenosis were recorded.Results The operative success rate,preoperative and postoperative mean stenosis rate were 100％,82.3％ ±9.6％ and 23.3％ ±12.0％ respectively.No nervous system complication and death occurred.The patients were followed up for 3-64 (34.4± 18.5) months,during which serevere ischemic stroke occurred in 1 patient (2.5％) due to instent occlusion.Of the 25 patients (62.5％) who underwent DSA reexamination,instent restenosis occurred in 12 (48.0％) including 3 with instent occlusion.The rate of Enterprise instent restenosis was higher than that of Wingspan instent restenosis or Apollo instent restenosis.The incidence of instent restenosis was higher in patients with their residual stenosis rate ＞ 35％ than in those with their residual stenosis rate ＜35％ (P＞0.05).Conclusion Stenting angioplasty is safe and effective for elderly patients with severe symptomatic intracranial vertebral artery atherosclerotic stenosis.
