I63.21
Cerebral infarction due to unspecified occlusion or stenosis of vertebral arteries
Clinical Classification Guidelines
Medical Intelligence & Overview
Cerebral infarction, often referred to as a stroke, occurs when blood flow to a part of the brain is blocked, leading to brain cell damage or death. Specifically, ICD-10 Code I63.21 pertains to a cerebral infarction caused by an unspecified occlusion or narrowing (stenosis) of the vertebral arteries. These arteries are critical blood vessels that supply blood to the posterior part of the brain, including areas responsible for balance, coordination, and basic bodily functions. When they become narrowed or blocked, it can result in significant neurological impairments and demands prompt medical attention.
Causes & Symptoms
Clinical Causes: Atherosclerosis leading to plaque buildup within the vertebral arteries. Blood clots or emboli obstructing the arteries. Narrowing or stenosis of the arteries due to injury or congenital conditions. Arterial dissection (tear within the artery wall). Inflammation or infection affecting the blood vessel walls.
Key Symptoms: Sudden weakness or numbness in the limbs, face, or one side of the body. Difficulty speaking or understanding speech. Problems with vision, such as sudden blurry or double vision. Dizziness or loss of balance and coordination. Severe headache with no known cause. Difficulty swallowing or breathing in severe cases. Loss of consciousness or fainting in some instances.
Diagnostic & Treatment
Diagnosis Path: Diagnosing a cerebral infarction due to vertebral artery occlusion involves a combination of clinical evaluation and imaging tests. Common diagnostic procedures include:
Treatment Protocols: Treatment strategies aim to restore blood flow, prevent further strokes, and manage underlying risk factors. Typical approaches may include:
