North American Symptomatic Carotid Endarterectomy Trial "NASCET"


Phase 3 Results


The risk of ipsilateral stroke was reduced significantly (p=0.045) in patients with carotid stenosis 50-69% who received carotid endarterectomy. Patients with stenosis of 70-99% showed the most significant reduction (p < 0.001) in the rate of ipsilateral stroke while patients with stenosis of <50% did not show a significantly lower rate of ipsilateral stroke.
