Angioplasty and stent placement - carotid artery

Carotid angioplasty and stenting; CAS; Angioplasty - carotid artery; Carotid artery stenosis - angioplasty;

The blood vessels that bring blood to your brain and face are called the carotid arteries. You have a carotid artery on each side of your neck.

The blood flow in this artery can become partly or totally blocked by fatty material called plaque. A partial blockage is called carotid artery stenosis (narrowing). A blockage in your carotid artery can reduce the blood supply to your brain. Sometimes part of a plaque can break off and block off another artery. A stroke can occur if your brain does not get enough blood.

Two procedures can be used to treat a carotid artery that is narrowed or blocked. These are:

  • Surgery to remove plaque buildup (endarterectomy)
  • Carotid angioplasty with stent placement
Atherosclerosis of internal carotid artery

The build-up of plaque in the internal carotid artery may lead to narrowing and irregularity of the artery's lumen, preventing proper blood flow to the brain. More commonly, as the narrowing worsens, pieces of plaque in the internal carotid artery can break free, travel to the brain and block blood vessels that supply blood to the brain. This leads to stroke, with possible paralysis or other deficits.

Carotid stenosis, X-ray of the right artery

This is an angiogram of the right carotid artery showing a severe narrowing (stenosis) of the internal carotid artery just past the carotid fork. There is enlargement of the vein or ulceration in the area after the stenosis in this close-up film. Note the narrowed segment toward the bottom of the picture.

Cholesterol producers

Cholesterol is a waxy, fat-like material that is found in all parts of the body. It comes from two sources: our liver produces it, and we consume it in meat and dairy products.
