Carotid Angiogram- About the Exam

Carotid angiogram is performed to diagnose and treat abnormalities in the carotid artery of the neck. A carotid angiogram can detect atherosclerotic, plaque disease in the carotid artery which can limit blood flow to the brain and cause a stroke. In some cases, a contrast material is injected to produce clearer images of the blood vessels.

What you can expect during a carotid angiogram:

  • The neck will be cleansed with an antiseptic to avoid infection at the site of the biopsy.
  • The area near the carotid artery will be sterilized to prevent infection.
  • A small incision will be made at the site and, using imaging, a catheter is inserted through the skin into a blood vessel and navigated to the area to be examined.
  • Contrast material is then injected into the catheter. Images will then be taken or the area.
  • At the end of the procedure, the catheter will be removed and pressure will be applied to stop any bleeding.
