CEA is most helpful for people who have carotid artery disease and one or more of the following:
- A prior stroke.
- A prior transient ischemic attack (TIA), also called a "mini-stroke." During a TIA, you may have some or all of the symptoms of a stroke. However, the symptoms usually last less than 1–2 hours (although they may last up to 24 hours).
- Severely blocked carotid arteries (even if you don't have stroke symptoms).
Other Treatments for Carotid Artery Disease
Anticlotting medicines, such as aspirin and clopidogrel, also are used to treat people who have carotid artery disease. These medicines help reduce blood clotting and lower the risk of stroke.
A procedure called carotid angioplasty may be used instead of CEA to treat blocked carotid arteries. For this procedure, a thin tube with a balloon on the end is threaded to the narrowed or blocked carotid artery.
Once in place, the balloon is inflated to push the plaque outward against the wall of the artery. Usually, the doctor then places a small metal stent (tube) in the artery. The stent reduces the risk that the artery will become blocked again.
