[Multiple Brain Embolism Due to Brachiocephalic Artery:A Case Report].

Area of Science:

• Vascular Neurology
• Cardiology
• Radiology

Background:

• Cerebral embolism is a significant cause of stroke.
• Embolisms originating from the brachiocephalic artery are exceptionally rare.
• Identifying the source of cerebral embolism is crucial for effective treatment.

Observation:

• A 71-year-old male with hypertension, diabetes, and hyperlipidemia presented with acute neurological deficits.
• Imaging revealed cerebral infarction in multiple vascular territories inconsistent with typical major artery stenosis or atrial fibrillation.
• A calcified lesion at the origin of the brachiocephalic artery was identified as the source of a floating thrombus.

Findings:

• The patient experienced a cerebral embolism attributed to a clot originating from the brachiocephalic artery.
• Anticoagulant therapy led to the resolution of the floating thrombus within three months.
• The embolism affected the right internal carotid artery and basilar artery territories, causing widespread cerebral infarction.

Implications:

• This case highlights the importance of investigating rare sources of cerebral embolism, even when typical causes are absent.
• Advanced imaging modalities are essential for elucidating the etiology of cerebral embolism when the vascular territory is atypical.
• Understanding emboli origin from the brachiocephalic artery can refine stroke prevention and treatment strategies.
