Carotid artery surgery
When you need it—and when you don’t
There are two large arteries in the front of the neck. They are the carotid arteries, and they take blood to the brain. If one is blocked, it can lead to a stroke.
The surgery to clear a blocked artery is called a “carotid endarterectomy” (CEA). If you have a blocked artery, you may wonder if you need a CEA. But if you haven’t had symptoms, you should think twice about having CEA surgery. Here’s why:
Surgery usually isn’t needed if you don’t have symptoms.
If you have had a stroke or mini-stroke (TIA), the CEA surgery may help you avoid another stroke. The surgery is most likely to help if your arteries are very blocked.
But if you have not had a stroke or a mini-stroke, the benefit of surgery is small. There are better ways to reduce the risk of stroke, including lifestyle changes and new medicines.
The surgery has serious risks.
CEA can have serious complications, including stroke, heart attack, and death. You are more likely to have complications if you are age 75 or older or if you have a serious medical condition, such as:
• Severe heart or lung disease
• Heart failure
• Had a heart attack
The surgery can cost a lot.

When should you have carotid artery surgery?
Consider a CEA in the following cases:
• Your carotid artery is severely blocked and has already caused a stroke or mini-stroke. In this
case, the surgery can greatly reduce your risk of another stroke.
• You have moderate blockage but you have had a stroke or mini-stroke. A CEA may help if you
have it soon after your stroke or mini-stroke.
• You have severe blockage but you have not had a stroke or mini-stroke. You are 40 to 75 years old
and your risk of complications from surgery is low.
In this case, make sure your surgeon has a low complication rate for people without symptoms. It should be less than three percent, and preferably much lower. You can find more information at www.consumerreports.org/ health/doctors-hospitals/hospital-ratings.htm.
