Carotid stenosis is a medical condition that affects the carotid arteries in your neck, which are vital for supplying blood to your brain. When these arteries become narrow or blocked, it can lead to serious health problems, including strokes. In this article, we’ll explain carotid stenosis, its types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical options in simple language to help you understand this condition better.
Carotid stenosis happens when the carotid arteries get clogged or narrowed. These arteries carry blood from your heart to your brain, and when they’re not working well, it can be a problem.
Types of Carotid Stenosis:
There are two main types:
- Atherosclerotic Stenosis: This occurs when fatty deposits build up in the arteries over time, making them narrower.
- Fibromuscular Dysplasia: This is a rare condition where the artery walls become abnormal and narrow.
Causes of Carotid Stenosis
- Smoking: Smoking can damage your arteries and lead to blockages.
- High Blood Pressure: High blood pressure can harm your arteries over time.
