目的分析支架成形术治疗67例症状性椎动脉起始段狭窄的效果。方法所有病例均具有药物难治性症状,共完成74枚球扩支架的血管内置入。结果血管的狭窄率从74.5%(50%～99%)下降到4.8%(0～20%),未发生与操作相关的并发症。27例的血管管径恢复正常,术后症状消失,无神经功能缺损。对18例术后6个月造影复查,有2例出现再狭窄。结论血管内支架置入治疗症状性椎动脉起始段狭窄的近期疗效令人满意,但长期的临床观察及造影复查是必要的。
Objective To analyze the effect of stenting for the treatment of 67 cases of symptomatic vertebral artery stenosis. Methods All patients were refractory to drug-induced symptoms, a total of 74 spherical stent placement of the blood vessels into the. Results Vascular stenosis rates decreased from 74.5% (50% to 99%) to 4.8% (0 to 20%) with no complications associated with the procedure. 27 cases of vascular diameter returned to normal, postoperative symptoms disappeared, no neurological deficit. 18 cases of postoperative 6 months angiography review, 2 cases of restenosis. Conclusion The short-term curative effect of endovascular stent implantation for the treatment of symptomatic vertebral artery stenosis is satisfactory, but long-term clinical observation and radiographic review are necessary.
