Treatment of Restenosis after PTA for Internal Carotid Stenosis.
Thirteen cases of restenosis occurred after percutaneous transluminal angioplasty (PTA) in 63 cases of internal carotid stenoses. They were treated by PTA or carotid endarterectomy. The patients were sufficiently informed of each treatment. Seven of them were initially treated by repeated PTA. The stenosis ratio improved from 82% to 30% after repeated PTA on average. However, one case in the PTA treated group resulted in restenosis and then carotid endarterectomy was performed. The other case also caused restenosis and was treated by PTA. Six cases were initially treated by carotid endarterectomy and all cases were successfully treated without difficulty. The success rate of the PTA was 2/7 (29%) in restenosis cases. One case causing re-restenosis had severe calcification in the arterial wall. PTA was thought to be effective for the restenosis cases after initial PTA if the arterial calcification was not severe.
