Among patients with symptomatic carotid artery stenosis, carotid artery stenting (CAS) is associated with a higher risk of periprocedural stroke or death than carotid endarterectomy (CEA). Uncertainty remains whether the balance of risk changes with time since the most recent ischemic event. ⋯ The increase in risk of CAS compared with CEA appears to be greatest in patients treated within 7 days of symptoms. Early surgery might remain most effective in stroke prevention in patients with symptomatic carotid artery stenosis.
