I65.02
Occlusion and stenosis of left vertebral artery
Clinical Classification Guidelines
Medical Intelligence & Overview
Occlusion and stenosis of the left vertebral artery are serious medical conditions affecting blood flow to the brain. The vertebral arteries are vital blood vessels that supply blood to parts of the brain, including the cerebellum and the posterior part of the brain. When these arteries become narrowed (stenosis) or blocked (occlusion), it can lead to significant neurological issues, including strokes. Recognizing the symptoms and understanding the causes can help in early diagnosis and management of this condition.
Causes & Symptoms
Clinical Causes: Atherosclerosis: Build-up of fatty plaques inside the artery wall, leading to narrowing or blockage. Embollism: Blood clots or other debris traveling from elsewhere and lodging in the vertebral artery. Vasculitis: Inflammation of the blood vessels that can cause narrowing or damage. Arterial dissection: Tear in the artery wall leading to blood entering between layers and causing stenosis or occlusion. Congenital abnormalities: Rare structural anomalies present from birth that affect artery width or integrity. External compression: Tumors or other masses pressing on the artery, reducing blood flow.
Key Symptoms: Dizziness or vertigo Difficulty with balance or coordination Loss of vision in one or both eyes Headache, often located at the back of the head Weakness or numbness, especially on one side of the body Difficulty swallowing or speaking Sudden confusion or memory problems Signs of stroke such as sudden weakness or paralysis Drop attacks or feeling of instability
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a combination of physical examinations and imaging studies. Common tools include:
Treatment Protocols: Management of occlusion and stenosis of the left vertebral artery focuses on restoring blood flow, preventing stroke, and managing risk factors. Common approaches include:
