Cerebral infarction due to thrombosis of posterior cerebral artery
ICD-10 I63.33 is a used to indicate a diagnosis of cerebral infarction due to thrombosis of posterior cerebral artery.
Cerebral infarction due to thrombosis of the posterior cerebral artery is a type of ischemic stroke that occurs when a blood clot obstructs blood flow in the posterior cerebral artery (PCA), which supplies blood to the occipital lobe and parts of the temporal lobe. Clinically, patients may present with sudden onset of visual disturbances, such as homonymous hemianopia, and may experience sensory deficits or cognitive changes depending on the extent of the infarction. The PCA is crucial for visual processing, and infarction in this area can lead to significant neurological deficits. Disease progression can vary; some patients may recover partially or fully, while others may experience long-term disability. Diagnostic considerations include neuroimaging techniques such as CT or MRI to confirm the presence of an infarct and to rule out hemorrhagic stroke. Additionally, risk factors such as hypertension, diabetes, and hyperlipidemia should be assessed to guide management and prevention strategies.

I63.33 specifically covers cerebral infarctions resulting from thrombosis of the posterior cerebral artery. This includes ischemic strokes that lead to neurological deficits primarily affecting visual processing and sensory functions.
I63.33 should be used when the cerebral infarction is specifically due to thrombosis of the posterior cerebral artery, distinguishing it from other types of strokes such as those due to embolism or occlusion of different arteries.
Documentation should include clinical findings, imaging results confirming the infarction in the posterior cerebral artery, and a detailed account of the patient's symptoms and risk factors.
