Vertebral Artery Thrombosis occurs when blood clots form in the vertebral arteries, crucial vessels that supply blood to the brain. In this article, we’ll break down the condition into simple terms, exploring its types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical options.
Types of Vertebral Artery Thrombosis:
- Embolic Thrombosis: Caused by blood clots that travel from other parts of the body to the vertebral arteries.
- In-situ Thrombosis: Blood clots form directly in the vertebral arteries.
Causes
