目的研究支架成形术治疗症状性椎动脉起始部狭窄的效果及安全性。方法对28例症状性椎动脉起始部狭窄的患者行腔内支架成形术治疗。28例患者均成功地植入球囊扩张式支架,无1例发生严重并发症。结果术后患者动脉狭窄程度均明显改善,症状均得到改善。6例患者获得脑血管造影随访,其中1例出现约50%的再狭窄。结论支架成形术是治疗症状性椎动脉起始部狭窄的安全、有效的方法,其长期的效果还需要进一步随访研究。
Objective To study the effect and safety of stenting for the treatment of symptomatic vertebral artery stenosis. Methods 28 cases of symptomatic vertebral artery stenosis patients underwent endovascular stent. Twenty-eight patients were successfully implanted with balloon-expandable stents, none of whom experienced serious complications. Results The degree of arterial stenosis was significantly improved and the symptoms were improved. Six patients were followed up for cerebrovascular angiography, of which 1 showed approximately 50% restenosis. Conclusion Stentoplasty is a safe and effective method for the treatment of symptomatic vertebral artery stenosis. Long-term results need further follow-up studies.
