椎动脉支架成形术治疗椎动脉狭窄疗效观察

The curative effect of symptomatic vertebral artery stenosis on vertebral artery stent angioplasty

目的探讨椎动脉支架成形术治疗椎动脉狭窄的安全性和有效性。方法对15例症状性椎动脉狭窄患者予以椎动脉支架成形术治疗。结果 15例患者成功植入16枚球囊扩张支架,术前术后平均狭窄程度分别为(81.7±4.8)%和(11.2±2.1)%;3个月随访12例症状消失,3例症状明显改善。结论椎动脉支架成形术是治疗椎动脉狭窄的安全有效方法,长期疗效需进一步观察。

Objective To observe the feasibility and safety of vertebral artery stent angioplasty for treating the patients with symptomatic vertebral artery stenosis.Methods 15 patients with symptomatic vertebral artery stenosis were performed vertebral artery stent angioplasty.Results 15 cases were successfully treated with 16 balloon-expanded stent,the mean degree of preoperative and postoperative stenosis were 82%and 11%,respectively.Follow up data showed disappearance of clinical symptoms in 12 patients,clinical significant improvement in 3 patients.Conclusion Vertebral artery stent angioplasty is a safety and efficient method for the treatment of vertebral arterial stenosis,but long term follow-up is necessary to ensure the curative effect.
