CONCLUSIONS	In conclusion , with the Rosuvastatin Pretreatment to Reduce Embolization during Carotid Artery Stenting trial , we want to evaluate whether a high dose of rosuvastatin for 6 weeks before CAS in asymptomatic patients with severe carotid stenosis is able to reduce the rate of plaque embolization during the procedure , thus suggesting a possible reduction in cerebral ischemic complications .\
