What is Carotid Angiography?
Carotid angiography is an outpatient procedure that helps find problems in blood vessels leading to your brain. These vessels include the carotid arteries, which supply your brain with blood. The procedure makes a “map” of your blood vessels. This map can show a narrowing in your arteries. Narrowing can cause numbness, weakness, trouble with speech, or changes in vision. These symptoms may be warning signs of a stroke.
Carotid angiography is often used in planning surgery to open a narrowed carotid artery. Your doctor will let you know whether surgery or another treatment is needed.
