80例支架植入术治疗椎动脉起始部狭窄的临床疗效长期随访

目的 探讨支架植入术治疗椎动脉起始部狭窄的安全性及有效性。方法 回顾性分析2009年1月至2014年1月在长沙市第一医院神经内科住院的80例椎动脉起始部狭窄患者进行支架成形术治疗的病例资料，并对其进行随访，观察其治疗的安全性及长期疗效。结果 80例患者成功植入80枚支架，技术成功率100%；放入支架前椎动脉狭窄率为（76.67±4.03）%，放入支架后椎动脉狭窄率为（13.70±1.88）%；80例患者最长随访7年，最短随访2年，失访1例，2例发生支架内再狭窄，再狭窄率3.75%。58例患者临床症状消失，21例临床症状缓解，1例临床症状加重，总有效率98.75%。结论 支架成形术治疗椎动脉起始部狭窄是一种非常安全及有效的方法。

Long-term Follow-up of 80 Patients with Stenosis in the Beginning Part of Vertebral Artery Treated with Stent Angioplasty

Objective To investigate the efficacy and safety of the stent angioplasty in treatment of stenosis in the starting part of vertebral artery. Methods 80 cases patients with stenosis in the beginning part of vertebral artery treated with stent angioplasty from January 2009 to January 2014 in the Neurology Department of the First Hospital of Changsha were selected for a retrospective analysis, and long-term follow-up. Results 80 brackets were successfully put in 80 patients with the technical success rate 100%. The stenosis rate after stent angioplasty was (13.70±1.88)%, and the previous rate was (76.67±4.03)%. We followed up the 80 patients, with the longest time for 7 years and the shortest time for 2 years. One case was lost to follow up, and 2 cases of patients were in-stent restenosis with restenosis rate for 3.75%. The clinical symptoms of 58 patients were cured, 21 patients alleviated, and one case aggravated. The total effective rate was 98.75%. Conclusion The stent angioplasty is a very safe and effective method in treatment of stenosis in beginning part of vertebral artery.
