Carotid Artery Problems: Surgery for TIAs
- VHL HealthSheet #83086_VA
The carotid artery is a blood vessel in your neck. A transient ischemic attack (TIA) is when narrowing in this artery blocks blood to your brain for a short time. It is caused by a substance called plaque that has built up in your artery. A TIA does not cause permanent damage to the brain. Symptoms go away within 24 hours.
