I63.432
Cerebral infarction due to embolism of left posterior cerebral artery
Clinical Classification Guidelines
Medical Intelligence & Overview
Cerebral infarction due to embolism of the left posterior cerebral artery is a type of stroke caused by a blockage in a specific blood vessel supplying blood to parts of the brain. This condition leads to the death of brain tissue in the affected area, often resulting in neurological deficits. The posterior cerebral artery plays a crucial role in supplying blood to the occipital lobe, thalamus, and parts of the temporal lobe, impacting vision, memory, and other functions when compromised.
Causes & Symptoms
Clinical Causes: Embolism originating from a clot or debris traveling through the bloodstream and lodging in the left posterior cerebral artery. Atrial fibrillation leading to formation of blood clots in the heart that can travel to cerebral arteries. Other sources of emboli such as heart valve disease, patent foramen ovale, or carotid artery plaques.
Key Symptoms: Visual disturbances, such as loss of vision in the affected visual field, often on the same side as the infarction. Difficulty recognizing objects or faces (visual agnosia). Memory impairment or deficits in understanding visual information. Weakness or numbness on the opposite side of the body from the infarct. Possibility of sensory loss or coordination problems depending on the extent of the stroke.
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of clinical evaluation and imaging studies. Typically, doctors use neuroimaging techniques such as MRI or CT scans to confirm the location and extent of the infarction. Carotid and cerebral artery imaging, like angiography or ultrasound, may be performed to identify potential sources of emboli. Additionally, cardiac evaluations, including ECG and echocardiography, help identify cardiac sources of emboli.
Treatment Protocols: Treatment aims to restore blood flow, prevent further embolic events, and manage neurological symptoms. It may include:
