Your carotid arteries are located on each side of your neck and extend from your aorta in your chest to base of your skull. These arteries supply blood to your brain. You have one main carotid artery on each side, and each of these divides into two major branches, the external and internal carotid arteries. The external carotid supplies the blood to your face and scalp. Your internal carotid artery is more important because it supplies blood to your brain.
When plaque builds up and reduces blood flow in your carotid arteries, you have carotid artery disease. This is a serious issue because clots can form on the plaque and block the blood flow to your brain, it can cause an ischemic stroke, which can cause brain damage or death. An ischemic stroke is a stroke that occurs because there is a lack of blood flow to cells in the brain.
Carotid stenting is a minimally invasive procedure that involves placement of a stent into the carotid artery. The procedure involves a vascular surgeon inserting a slender, metal-mesh tube, called a stent, which expands inside your carotid artery to increase blood flow in areas blocked by plaque.
