Cerebral Aneurysms: Evaluation and All Treatment Options
Overview
Carotid stenting is a minimally invasive treatment used in selected patients with carotid artery narrowing, usually caused by atherosclerotic plaque in the carotid arteries of the neck. These arteries supply blood to the brain, and significant narrowing can increase the risk of stroke or transient ischemic attack (TIA).
What is carotid stenosis?
Carotid stenosis means narrowing of the carotid artery, usually from plaque buildup. Over time, plaque can reduce blood flow or shed embolic material to the brain. This can cause transient neurologic symptoms, stroke, or no symptoms at all until discovered on ultrasound or vascular imaging.
Symptoms
Some patients with carotid stenosis may have:
- Transient weakness or numbness of the face, arm, or leg.
- Trouble speaking or understanding language.
- Vision loss in one eye.
- Prior TIA or ischemic stroke.
Any sudden neurologic deficit should be treated as an emergency and should prompt immediate emergency evaluation.
How carotid disease is diagnosed
Carotid narrowing may be evaluated with:
- Carotid ultrasound.
- CT angiography.
- MR angiography.
- Catheter angiography in selected cases when anatomy or treatment planning requires further clarification.
Treatment
Many patients with carotid stenosis are treated initially or exclusively with medical therapy. This may include:
- Antiplatelet medication.
- Statin therapy.
- Blood pressure control.
- Diabetes management.
- Smoking cessation.
- Lifestyle and vascular risk reduction.
- Procedure-based therapy
What to expect before and after stenting
Evaluation usually includes review of symptoms, imaging, medical history, blood-thinner requirements, and anatomy of the aortic arch and carotid vessels. After treatment, follow-up can include neurologic monitoring, blood pressure management, continuation of prescribed medications, and surveillance imaging over time.
