I65.01
Occlusion and stenosis of right vertebral artery
Clinical Classification Guidelines
Medical Intelligence & Overview
Occlusion and stenosis of the right vertebral artery are medical conditions involving the narrowing or blockage of this vital vessel that supplies blood to the brain. The vertebral arteries travel through the neck, entering the skull to connect to the basilar artery, which supplies blood to essential parts of the brain, including the cerebellum and the brainstem. When these arteries are narrowed or blocked, it can lead to reduced blood flow, increasing the risk of stroke or transient ischemic attack (TIA). This information aims to provide a clear understanding of the condition, its causes, symptoms, and potential management strategies.
Causes & Symptoms
Clinical Causes: Atherosclerosis (buildup of fatty deposits inside the artery walls) Arterial dissection (tear in the artery wall) Vascular inflammation (vasculitis) Embollism (blockage caused by clots or debris traveling from elsewhere) Congenital abnormalities that narrow the artery Chronic hypertension leading to arterial damage
Key Symptoms: Dizziness or vertigo Balance and coordination problems Difficulty speaking or swallowing Visual disturbances such as blurred vision Weakness or numbness on one side of the body Sudden severe headache Loss of consciousness or fainting
Diagnostic & Treatment
Diagnosis Path: Diagnosing occlusion or stenosis of the right vertebral artery includes a combination of medical history assessment and imaging studies. These may involve:
Treatment Protocols: Management of this condition focuses on restoring blood flow, preventing further artery damage, and reducing stroke risk. Treatment options may include:
