Effects of Cerebral Protection With Filters vs. Flow Reversal on Cerebral Embolization After Carotid Artery Stenting

"Patients randomized to this group will receive filter devices to prevent cerebral embolization during carotid stenting, assessed by intraoperative transcranial Doppler and postoperative cerebral DW-MRI.~The filter used for this trial is the RX accunet embolic protection system manufactured by abbott."

On the flow reversal arm two type of devices will be used. The first is the Gore flow reversal system, manufactured by LW Gore and the second device is the IVANTEC MoMa Ultra Embolic protection device, manufatured by IVANTEC.
