Carotid Angioplasty and Stenting (CAS) is a catheter-based procedure used to open narrowed or blocked carotid arteries — the major blood vessels in the neck supplying blood to the brain. By restoring blood flow and stabilizing plaque, CAS plays a vital role in stroke prevention, especially in high-risk or symptomatic patients.
Carotid angioplasty and stenting restores blood flow to the brain and helps prevent stroke in high-risk patients.
The carotid arteries supply nearly 70–80% of blood flow to the brain. When these arteries become narrowed (carotid artery stenosis), the risk of stroke, transient ischemic attack (TIA), and sudden neurological deficits increases significantly.
- Atherosclerosis (fatty plaque buildup)
- Diabetes and high blood pressure
- High cholesterol
- Smoking and tobacco use
- Age above 60 years
- Family history of stroke or vascular disease
Warning Signs & Symptoms
Carotid artery stenosis is often silent until a stroke occurs. Symptoms may appear suddenly and require urgent medical attention.
Symptoms may include sudden weakness or numbness of the face, arm, or leg; difficulty speaking; slurred speech; sudden vision loss; and loss of balance or coordination.
TIAs or “mini-strokes” are warning signs that indicate a high risk of a future major stroke and should never be ignored.
CAS is recommended for symptomatic patients with ≥70% stenosis, asymptomatic patients with 80% stenosis, and patients unsuitable for surgery due to high surgical risk.
The procedure is performed under local anesthesia using femoral or radial access. A filter device prevents debris embolization, a balloon opens the narrowing, and a self-expanding stent keeps the artery open.
Carotid stenting prevents future stroke, avoids open neck surgery, offers faster recovery, and shows excellent long-term stent patency with reduced stroke risk.
