During angioplasty, a balloon catheter is guided to the area of the blockage or narrowing. When the balloon is inflated, the fatty plaque or blockage is compressed against the artery walls to improve blood flow. A carotid stent is placed inside the carotid artery at the site of the blockage and provides support to keep the artery open.
For patients who meet certain eligibility criteria, carotid stenting offers a less invasive approach than carotid endarterectomy, the traditional surgical treatment for carotid artery blockages.
Carotid stenting can be performed while the patient is awake, reducing recovery time.
