G45.0
Vertebro-basilar artery syndrome
Clinical Classification Guidelines
Medical Intelligence & Overview
Vertebro-basilar artery syndrome is a neurological condition caused by compromised blood flow through the vertebral and basilar arteries, which supply blood to the brainstem, cerebellum, and posterior parts of the brain. This condition can lead to a range of symptoms depending on the severity and location of the blockage or hemorrhage. Recognizing the signs and understanding its causes are crucial for timely medical attention and management.
Causes & Symptoms
Clinical Causes: Atherosclerosis (buildup of fatty deposits in the arteries) Embolism (blockage caused by a blood clot or other debris) Arterial dissection (tear in the artery wall) Vasculitis (inflammation of blood vessels) Blood vessel narrowing due to injury or congenital abnormalities Cardiac sources of emboli, such as atrial fibrillation Spasm or constriction of the arteries
Key Symptoms: Dizziness or vertigo Drop attacks or sudden loss of balance Double vision or difficulty focusing Weakness or numbness on one side of the body Difficulty speaking or swallowing Loss of coordination and ataxia Sudden severe headache Visual disturbances, such as loss of vision in one eye Nausea and vomiting
Diagnostic & Treatment
Diagnosis Path: Magnetic Resonance Imaging (MRI) of the brain for detailed images Magnetic Resonance Angiography (MRA) or CT Angiography to visualize blood vessels Carotid and vertebral artery Doppler ultrasound for blood flow assessment Digital Subtraction Angiography (DSA) in specific cases Blood tests to assess risk factors such as clotting disorders or inflammation
Treatment Protocols: Medications such as antiplatelets (aspirin) or anticoagulants to prevent clot formation Thrombolytic therapy in acute settings to dissolve blood clots Surgical interventions, including endarterectomy or carotid artery stenting, if applicable Lifestyle modifications like controlling blood pressure, cholesterol, and diabetes Rehabilitation therapies, including physical, speech, and occupational therapy, for recovery Addressing underlying causes such as atrial fibrillation or vasculitis
