I65.0
Occlusion and stenosis of vertebral artery
Clinical Classification Guidelines
Medical Intelligence & Overview
Occlusion and stenosis of the vertebral artery refer to conditions where the blood flow through this important artery is reduced or blocked. The vertebral arteries are major blood vessels that supply blood to the posterior part of the brain, including the cerebellum and brainstem. When these arteries become narrowed (stenosis) or completely blocked (occlusion), it can lead to symptoms impacting balance, coordination, and other neurological functions. Recognizing these conditions is crucial for timely management to prevent serious complications such as stroke.
Causes & Symptoms
Clinical Causes: Atherosclerosis: Build-up of fatty deposits inside the artery walls leading to narrowing or blockage. Vascular inflammation: Conditions like vasculitis that cause inflammation and damage to the vessel walls. Embryological abnormalities: Congenital defects that may predispose to narrowing or occlusion. Trauma: Injury to the neck or head that damages the vertebral artery. Large artery dissection: A tear in the artery wall can cause blood to enter the vessel wall, leading to stenosis or occlusion. Takayasu arteritis: A rare inflammatory disease that affects large arteries, including the vertebral arteries.
Key Symptoms: Dizziness or vertigo Loss of balance or coordination Blurred or doubled vision Rarely, sudden headache or neck pain Weakness or numbness on one side of the body Difficulty speaking or swallowing in severe cases Transient ischemic attacks (TIAs) or warning strokes
Diagnostic & Treatment
Diagnosis Path: The diagnosis of vertebral artery occlusion or stenosis involves a combination of clinical assessment and imaging studies. These may include ultrasound Doppler studies, magnetic resonance angiography (MRA), computed tomography angiography (CTA), and conventional angiography. These imaging techniques help visualize blood flow and identify areas of narrowing or blockage in the vertebral arteries.
Treatment Protocols: Treatment strategies aim to restore and maintain adequate blood flow to prevent strokes. Approaches may include:
