Open carotid endarterectomy is a procedure used to treat carotid artery disease by surgically removing plaque buildup from the carotid arteries, which supply blood to the brain. The surgery is performed through an incision in the neck, allowing the surgeon to access and clean the carotid artery. This reduces the risk of stroke caused by blocked or narrowed arteries.

Carotid endarterectomy is effective in preventing strokes and improving brain health, particularly in patients with significant narrowing of the carotid arteries.
