Why may I need carotid artery stenting?

Carotid artery stenting is done to lower your risk of stroke or transient ischemic attack (TIA).

Your doctor may suggest that you have carotid artery stenting if:

• You have had a mild stroke or one or more transient ischemic attacks (TIAs) in the past 6 months, and your carotid artery is narrowed by 70% or more.
• You have a low risk for having problems (complications) from the procedure.
• You have a high risk of complications from carotid artery surgery (carotid endarterectomy).
