Carotid Artery Anatomy with Angiography. Carotid angiography, also called carotid angio or an arteriogram, is an invasive X-ray imaging procedure used to detect the presence of narrowing or blockage (atherosclerosis) in the carotid arteries and determine your risk for future stroke.hen the balloon is inflated, the fatty plaque or blockage is compressed against the artery walls to improve blood flow. During the angioplasty procedure, a carotid stent (a small, metal mesh tube) is placed inside the carotid artery at the site of the blockage and provides support to keep the artery open.
