Carotid artery stenting (CAS) appears to be feasible, safe, and useful in patients with acute atherosclerotic extracranial internal carotid artery occlusions with severe stroke symptoms when used within the first 6 hours of symptom onset. In a small study, 95% of patients achieved successful revascularization with acute CAS. At 90 days, the mortality rate was 13.6%.
