Vertebral Artery Ischemia (VAI) is a condition where blood flow to the vertebrae, particularly through the vertebral artery, is restricted, leading to a lack of oxygen and nutrients. This condition can result in various symptoms and complications, making it crucial to comprehend its types, causes, symptoms, diagnostic tests, treatments, drugs, and surgeries.
Types of Vertebral Artery Ischemia:
- Embolic VAI:
- Description: Caused by blood clots or debris that travel to the vertebral artery, restricting blood flow.
- Defination: A type of VAI where blockages originate elsewhere and migrate to the vertebral artery.
- Thrombotic VAI:
- Description: Arises from the formation of a blood clot within the vertebral artery, impeding blood circulation.
- Definition: VAI caused by the local formation of blood clots within the vertebral artery.
Causes of Vertebral Artery Ischemia:
- Atherosclerosis
- Blood clots
- Trauma
- Infections
- Dissections (tearing of artery walls)
- Tumors
- Arterial spasms
- Rheumatoid arthritis
- Compression due to surrounding structures
- Connective tissue disorders
- Cervical rib
- Blood vessel inflammation
- High blood pressure
- Diabetes
- Smoking
- Hyperlipidemia (high cholesterol)
- Genetic factors
- Migraines
- Drug abuse
- Age-related degeneration
Symptoms of Vertebral Artery Ischemia:
- Dizziness
- Vertigo
- Nausea

- Description: Oral anticoagulant.
- Definition: A medication that inhibits blood clot formation.
- Enalapril:
- Description: ACE inhibitor.
- Definition: Medication that helps lower blood pressure.
- Dipyridamole:
- Description: A combination antiplatelet drug.
- Definition: Used to prevent blood clots.
