症状性颈动脉狭窄的血管内支架治疗

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。

The application of percutaneous transluminal stenting in patients with symptomatic carotid artery stenosis

Objective To assess the efficacy of the application of percutaneous transluminal stenting in patients with sympotomatic carotid artery stenosis. Methods Percutaneous transluminal self-expandable stenting was performed in 35 patients with carotid artery stenosis (luminal stenosis>70%). Among the 35 patients, the cerebral protection device was used in 27 patients, and balloon dilation was performed in 22 patients before placement of stents and in 5 patients after stenting. Results Stents were successfully implantated in all patients and 42 stents were placed. After stenting, residual stenosis was less than 20%. Of the 35 patients, 29 were cured and 6 were improved.All the patients were followed up for 1 to 36 months and there were no recurrence or restenosis.Conclusion Percutaneous transluminal stenting is an effective method in treating patients with symptomatic carotid arterial stenosis. The occurrence of restenosis after stent implantation remains to be evaluated in long-term follow-up.
