腔内支架成形术治疗椎动脉起始部狭窄

Transluminal stent-assisted angioplasty for the treatment of stenosis at original vertebral artery

目的探讨腔内支架成形术治疗椎动脉起始部狭窄的疗效。方法对16例椎动脉起始部狭窄的患者行腔内支架成形术治疗,成功置入17枚球囊扩张支架,无1例发生严重并发症。结果术后造影狭窄程度明显改善,残余狭窄<20%。在6个月的临床随访中,16例患者均无脑缺血发作及再狭窄发生。颈动脉彩超示血流通畅,未见内膜过度增生。结论腔内支架成形术是治疗椎动脉起始部狭窄的安全、有效的方法,其长期效果还需进一步随访研究。

Objective To discuss the curative effection of the patients who was disposed stent at original vertebral artery stenosis section.Methods Transluminal stent-assisted angioplasty was performed in 16 cases with stenosis at original vertebral.All cases were successfully treated with 17 baloon-expanded stents without severe complications.Results After the operation,the degree of stenosis was significantly deceased no more than 20%.During clinical follow up for 6 months,no cerebral ischemic attack was noted for all patients,and carotid artery colour doppler revealed no restenosis and intimal hyperplasia.Conclusion Percutaneous transluminal stenting is safe and effective for stenosis at original vertebral.And the long-term follow-up needs further investigation.
