I63.43
Cerebral infarction due to embolism of posterior cerebral artery
Clinical Classification Guidelines
Medical Intelligence & Overview
Cerebral infarction, commonly known as a stroke, occurs when blood flow to a part of the brain is blocked, resulting in damage to brain tissue. The specific type identified by ICD-10 code I63.43 refers to a cerebral infarction caused by an embolism blocking the posterior cerebral artery. This artery supplies blood to parts of the brain responsible for visual processing, memory, and sensory interpretation. Recognizing this subtype is important because it influences treatment approaches and prognosis.
Causes & Symptoms
Clinical Causes: Embolism originating from the heart (e.g., atrial fibrillation, valvular heart disease). Blood clots forming elsewhere in the body and traveling to the brain via the bloodstream. Atherosclerosis leading to plaque rupture and embolus formation. Medical conditions like infective endocarditis which can produce emboli. Rarely, fat or air bubbles entering the circulation causing embolism.
Key Symptoms: Sudden visual disturbances, such as loss of vision in one or both eyes. Weakness or numbness on one side of the body, especially affecting the face, arm, or leg. Difficulty speaking or understanding speech. Sudden confusion or trouble with coordination and balance. Headache that may be severe and sudden in onset. Loss of consciousness in some cases. Altered sensation or perceptual deficits, such as difficulty perceiving objects or depth.
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a combination of clinical evaluation and imaging tests. Magnetic Resonance Imaging (MRI) is the preferred modality to visualize brain tissue damage and confirm the location of the infarct. Magnetic Resonance Angiography (MRA) or Computed Tomography Angiography (CTA) can help identify the site of arterial blockage or embolism. Additional assessments may include ultrasound of neck arteries and cardiac evaluation, such as echocardiography, to identify potential sources of emboli.
Treatment Protocols: Immediate management aims to restore blood flow, minimize brain damage, and prevent future events. Treatments may include:
