Vertebral Artery Stenosis
Vertebral Artery Stenosis: Understanding, Symptoms, and Treatment in Thousand Oaks, CA
The vertebral arteries play a vital role in delivering oxygenated blood to the brainstem, cerebellum, and posterior regions of the brain. When these arteries become narrowed (stenosis) due to plaque buildup or other vascular conditions, blood flow is restricted, increasing the risk of transient ischemic attacks (TIAs) and strokes. Left untreated, vertebral artery stenosis can lead to severe neurological complications and long-term disability.
At Vascular Neurology of Southern California (VNSC), we specialize in the early detection and treatment of vertebral artery disease. Our team offers cutting-edge diagnostics and personalized treatment plans to help restore healthy blood flow and reduce the risk of stroke.

What Is Vertebral Artery Stenosis?
Vertebral artery stenosis occurs when the arteries that supply the back portion of the brain become narrowed due to atherosclerosis, blood clots, or other vascular abnormalities. As blood flow decreases, critical areas of the brain receive less oxygen, which can result in serious neurological symptoms.
This condition is a leading cause of posterior circulation strokes, which can impact coordination, vision, and balance. Because vertebral artery stenosis often progresses silently, early detection is key to preventing life-altering complications.
Recognizing the Symptoms
The symptoms of vertebral artery stenosis can vary in intensity and may be mistaken for other conditions. Key signs include:
- Dizziness or vertigo – Sudden loss of balance or a spinning sensation
- Double vision or visual disturbances – Blurry or distorted vision
- Difficulty swallowing – Problems coordinating throat muscles
- Numbness or weakness – Particularly affecting the face or limbs
- Sudden headaches – Often severe and persistent
- Drop attacks – Unexpected falls without loss of consciousness
- Slurred speech or trouble speaking – Difficulty forming words
If these symptoms appear, especially in combination, seek immediate medical attention to reduce the risk of stroke.
What Causes Vertebral Artery Stenosis?
This condition is primarily caused by vascular diseases that affect artery health. Common contributing factors include:
The most common cause, where plaque buildup narrows the arteries.
Chronic hypertension can weaken artery walls.
Poorly managed blood sugar can contribute to vascular damage.
Tobacco use accelerates plaque accumulation and arterial narrowing.
Excess LDL cholesterol promotes atherosclerosis.
Cardiac conditions can lead to clot formation, which may block vertebral arteries.
Damage from whiplash or sudden movements may impact artery function.
Identifying and managing these risk factors is crucial for preventing further arterial narrowing and stroke risk.
How Is Vertebral Artery Stenosis Diagnosed?
At VNSC, we utilize advanced imaging technology to diagnose vertebral artery stenosis and determine the severity of the condition. Diagnostic methods include:
Evaluates blood flow in the vertebral arteries.
Provides a detailed view of the blood vessels in the neck and brain.
Captures high-resolution images to detect blockages or narrowing.
A minimally invasive test that provides precise images of the arteries.
Helps assess cholesterol, clotting factors, and other vascular risk indicators.
A comprehensive evaluation allows for the development of a targeted treatment plan tailored to each patient’s needs.
Treatment Approaches for Vertebral Artery Stenosis
The goal of treatment is to improve blood flow to the brain while reducing the risk of stroke. Treatment options include:
- Antiplatelet drugs (aspirin, clopidogrel) to prevent clot formation
- Statins to lower cholesterol and slow plaque buildup
- Blood pressure medications to reduce arterial stress
- Angioplasty and Stenting – A catheter-based procedure to widen narrowed arteries and place a stent to maintain blood flow.
- Thrombectomy – For acute cases, this procedure removes clots to restore circulation.
- Bypass Surgery – In severe cases, a new pathway for blood flow may be created to bypass the blockage.
- Adopting a heart-healthy diet with low saturated fats and high fiber
- Engaging in regular physical activity to support cardiovascular function
- Eliminating smoking and reducing alcohol intake
- Managing diabetes and hypertension with proper medical guidance
A combination of medical treatment and lifestyle modifications significantly reduces the risk of stroke and improves overall vascular health.
How Vertebral Artery Stenosis Differs from Middle and Basilar Artery Stenosis
While all three conditions affect major arteries supplying blood to the brain, they differ in location, symptoms, and potential complications:
- Vertebral Artery Stenosis affects the arteries in the neck that supply the brainstem and cerebellum. It primarily causes dizziness, balance issues, and visual disturbances.
Middle Cerebral Artery (MCA) Stenosis impacts a key artery supplying blood to the frontal, temporal, and parietal lobes. It is associated with weakness or paralysis on one side of the body, speech difficulties, and cognitive impairment.
Basilar Artery Stenosis affects the main artery supplying the brainstem. It can lead to life-threatening strokes, causing severe neurological dysfunctions like locked-in syndrome or loss of consciousness.
Understanding these distinctions helps in choosing the appropriate diagnostic and treatment approach for each condition.
