Balloon Catheter Dilatation and Internal Stent Placement in Treating Takayasu's Arteritis with Carotid Arterial Stenosis / 介入放射学杂志

ABSTRACT

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.
