Summary
A rare case of bilateral carotid artery occlusion presented with arm symptoms. The study highlights the vertebrobasilar system
Area of Science:
- Vascular Neurology
- Diagnostic Imaging
Background:
- Bilateral carotid artery occlusion is a rare condition.
- Understanding collateral circulation is crucial for managing such cases.
Observation:
- A 40-year-old male presented with right arm pain and numbness.
- Clinical examination revealed no neurological deficits.
- Duplex sonography showed no flow in bilateral common carotid arteries.
Findings:
- Cerebral digital subtraction angiography revealed total occlusion of the brachiocephalic trunk and left carotid artery.
- A moderate stenosis was noted in the left vertebral artery.
- Collateral circulation to the intracranial carotid system primarily originated from the left vertebrobasilar system.
Implications:
- This case underscores the importance of comprehensive vascular imaging in patients with non-specific neurological symptoms.
- The findings emphasize the critical role of the vertebrobasilar system in maintaining cerebral perfusion during bilateral carotid occlusion.
- Reviewing previous literature aids in understanding the pathophysiology and management strategies for this rare condition.
