摘要
目的:探讨应用球囊扩张和血管内支架治疗大动脉炎、颈动脉狭窄。材料和方法:3例大动脉炎性颈动脉狭窄的患者,狭窄段均超过8cm。1例单纯球囊扩张;2例球囊扩张后植入 Wallstent 支架。结果:术后狭窄率均为0,达到了良好的治疗效果,单纯球囊扩张的动脉一年后动脉完全闭塞。植入血管内支架的2例,分别是在4.5个月和4个月检查,一例血管内支架的近端出现了再狭窄,另一例未出现再狭窄。结论:对于大动脉炎性长段颈动脉狭窄的治疗,血管内支架是一种可以选择的方法。
Purpose:To evaluate the feasibility of balloon catheter dilatation and internal stent placement in the treatment of Takayasu's arterial stenosis.Materials and Methods:Three patients with stenosis of common carotid arteries caused by Takayasu' s disease were treated with PTA by balloon catheter and intravaseular stent placement,the lenghs of stenosis were all beyond 8cm.Balloon angioplasty was performed in one patient,the others were treated with Wallstent stents after PTA.Result:Immediately after treatment,angiography and ultrasound showed that the proportion of stenosis was zero and all appeared to achieve in good result.The artery treated with PTA was completely occluded after 1 year follow-up;the other two patients with stents placement were also examined by angiography and ultrasound at 4,5 months and 4 months respectively after the praeedure.For the patient with left carotid artery stenosis,the proximal part of the segment with the intravascular stent showed a restenosis;the other patient was normal.Conclusion:We considered that intravascular stent placement be might to the treatment for Takayacu' s arteritis with long segment stenosis of common carotid artery.
