大动脉炎颈动脉狭窄球囊扩张和内支架的治疗

目的：探讨应用球囊扩张和血管内支架治疗大支脉炎、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、西入血管内支架的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

Balloon Catheter Dilatation and Internal Stent Placement in Treating Takayasu's Arteritis with Carotid Arterial Stenosis

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.
