I66.09

Clinical Causes: Atherosclerosis leading to buildup of fatty deposits within the artery walls Blood clots that obstruct blood flow within the middle cerebral artery Emboli originating from other parts of the body traveling to the brain Vasculitis, which involves inflammation of blood vessels Rarely, trauma or injury causing vessel damage

Key Symptoms: Sudden weakness or numbness in the face, arm, or leg, typically on one side of the body Difficulty speaking or understanding speech Sudden confusion or problems with comprehension Sudden loss of vision or blurred vision in one or both eyes Trouble walking, dizziness, or loss of balance and coordination Severe headache that may be sudden and intense

Diagnosis Path: Neuroimaging: MRI or CT scans to visualize ischemic areas or blockages Angiography: Magnetic resonance angiography (MRA) or computed tomography angiography (CTA) to assess blood vessel status Ultrasound Doppler studies: To evaluate blood flow in cerebral arteries Clinical evaluation: Detailed neurological examination to identify deficits and symptoms

Treatment Protocols: Thrombolytic therapy: Use of clot-busting medications within a specific time window after symptom onset Endovascular procedures: Mechanical thrombectomy or angioplasty to physically remove or open narrowed arteries Medications: Antiplatelet agents or anticoagulants to prevent clot formation Blood pressure management: To maintain optimal cerebral perfusion Rehabilitation services: Physical, occupational, and speech therapy to recover neurological functions
