BACKGROUND: Endovascular treatment (angioplasty with or without stenting) is an alternative to carotid endarterectomy for carotid artery stenosis but there are scarce long-term efficacy data showing that it prevents stroke. We therefore report the long-term results of the Carotid and Vertebral Artery Transluminal Angioplasty Study (CAVATAS). METHODS: Between March, 1992, and July, 1997, patients who presented at a participating centre with a confirmed stenosis of the internal carotid artery that was deemed equally suitable for either carotid endarterectomy or endovascular treatment were randomly assigned to either treatment in equal proportions by telephone or fax from the randomisation serv..View full abstract
