Carotid endarterectomy (CEA) is fairly safe when done by surgeons who have experience with it. However, serious complications, such as stroke and death, can occur.
CEA also can cause less serious complications. For example, you may have a bad reaction to the anesthesia, bleeding, or infection. Short-term nerve injury may cause numbness in your face or tongue.
Certain factors may raise your risk of having CEA complications. For example, women are at higher risk of complications than men. Other risk factors include having diabetes or other serious medical conditions. People who are older than 75 and have other risk factors also are at higher risk.
Talk with your doctor about the risks of CEA. He or she can help you decide whether the surgery may benefit you.
