I65.03
Occlusion and stenosis of bilateral vertebral arteries
Clinical Classification Guidelines
Medical Intelligence & Overview
Occlusion and stenosis of the bilateral vertebral arteries refer to blockages or narrowing in these important blood vessels in the neck. These arteries supply blood to the back part of the brain, including the cerebellum and brainstem. When they are affected, it can impact blood flow and potentially lead to neurological issues. Recognizing and understanding these conditions is crucial for managing health and preventing complications.
Causes & Symptoms
Clinical Causes: Atherosclerosis (hardening of the arteries due to fatty deposits) Blood clots forming within the arteries Arterial dissection (tear in the artery wall) Vasculitis (inflammation of blood vessels) Congenital artery abnormalities External compression of the arteries Trauma to the neck or head
Key Symptoms: Dizziness or vertigo Blurred or loss of vision Weakness or numbness on one side of the body Difficulty speaking or swallowing Uncoordinated movements or balance problems Headache in the back of the head Transient ischemic attacks (brief episodes of neurological symptoms) In severe cases, stroke symptoms
Diagnostic & Treatment
Diagnosis Path: Doppler ultrasound to assess blood flow Magnetic resonance angiography (MRA) Computed tomography angiography (CTA) Digital subtraction angiography (DSA), which provides detailed images of blood vessels Neurological examinations to evaluate functional deficits
Treatment Protocols: Lifestyle modifications such as a healthy diet, exercise, smoking cessation, and managing blood pressure and cholesterol levels Medications including antiplatelet drugs, blood thinners, or statins Endovascular procedures like angioplasty or stenting to open narrowed arteries Surgical options, such as bypass surgery, in selected cases Managing underlying conditions like vasculitis or arterial dissection
