目的通过观察血管内支架置入术在治疗椎动脉开口狭窄患者的短期疗效,探讨其安全性与有效性。方法对2例经CTA证实椎动脉开口狭窄并符合支架置入指征的患者实施血管内支架置入,观察术后动脉狭窄改善及并发症的发生。术后随访6个月,复查CTA,行Malek评分。结果术后动脉狭窄改善率>70%,无并发症发生。在6个月随访中,Malek评分显著改善。结论血管内支架置入术可明显改善椎动脉狭窄,降低脑血管事件发生,安全有效。
Objective To observe the short-term effect of endovascular stenting in the treatment of open stenosis of vertebral artery and to explore its safety and effectiveness. Methods Two patients with open stenosis of vertebral artery confirmed by CTA and indications for stent placement were treated with endovascular stenting. The improvement of arterial stenosis and complication were observed. All cases were followed up for 6 months. CTA was performed and Malek scores were performed. Results Postoperative arterial stenosis improvement rate> 70%, no complications. The Malek score improved significantly at 6-month follow-up. Conclusion Endovascular stent placement can significantly improve the stenosis of vertebral artery and reduce the occurrence of cerebrovascular events, which is safe and effective.
