Having a stroke is one of the most frightening prospects of aging. Strokes can come on suddenly, stealing the use of an arm or the ability to speak. A stroke can be fatal or leave us permanently disabled.
About half of all strokes are caused by atherosclerosis -- the same process of narrowing and hardening of the arteries that causes heart attacks. Atherosclerosis progresses silently, without symptoms, putting our brains and our independence at risk.

For people who have partial obstruction of a carotid artery -- the artery in the neck that provides blood supply to the brain -- a surgery called a carotid endarterectomy may be an option to prevent a stroke or TIA. This procedure involves the removal of fat and plaque buildup from these arteries.
If diagnosed early, because of warning signs of a problem, a carotid aneurysm can be repaired, preventing a possible stroke.
