目的探讨血管内支架置放术治疗症状性颈动脉狭窄的临床效果。方法对35例颈动脉狭窄>70%的患者行血管内自膨式支架置放术,术中选用保护装置27例,行球囊预扩22例,行后扩5例。结果全部患者操作顺利,共置放支架42枚,影像学评价残余狭窄<20%。临床治愈29例,好转6例。随访1～36个月,症状无复发,无再狭窄。结论血管内支架置放术是治疗症状性颈动脉狭窄的一种有效方法,术后再狭窄有待于长期随访。
Objective To investigate the clinical effect of endovascular stent placement on symptomatic carotid artery stenosis. Methods 35 patients with carotid artery stenosis> 70% underwent endovascular stent placement. In the operation, 27 cases were selected with protective device, 22 cases were pre-expanded with balloon and 5 cases were performed with posterior extension. Results All the patients operated smoothly, a total of 42 stent placement, imaging evaluation of residual stenosis <20%. Clinical cure in 29 cases, improved in 6 cases. Follow-up 1 ~ 36 months, no recurrence of symptoms, no restenosis. Conclusion Endovascular stent placement is an effective method for the treatment of symptomatic carotid artery stenosis. Postoperative restenosis remains to be followed up for a long time.
