Thirty-five patients awaiting carotid stenting were randomized either to 300mg clopidogrel with aspirin or 600mg clopidogrel alone preoperatively. The effects on platelet aggregometry were similar, and there was no difference in the number of Doppler-detected microemboli during the stenting procedure.
