What antithrombotic regimen do you recommend prior to and in anticipation of CEA for patients with symptomatic carotid stenosis?  

Dual antiplatelet therapy with aspirin and clopidogrel

I prefer this regimen as well, but I make sure the surgeon won't delay treatment as a result of dual antiplt first. Most are changing their practice or are receptive to the data to support DAPT pre-op when presented with it.
