[Cervical spinal cord infarction in a patient with unilateral internal carotid artery occlusion and cervical
Insights
A patient experienced right hemiparesis due to cervical spinal cord infarction, linked to internal carotid artery occlusion. This condition may result from a steal phenomenon and local cervical spondylosis ischemia.
Area of Science:
- Neurology
- Vascular Neurology
- Spinal Cord Medicine
Background:
- Cervical spinal cord infarction is a rare condition.
- Internal carotid artery occlusion can lead to complex cerebrovascular events.
Observation:
- A 68-year-old male presented with right hemiparesis.
- Cerebral angiography showed right internal carotid artery occlusion.
- The right middle cerebral artery was supplied by the basilar artery via the posterior communicating artery.
Findings:
- The patient's condition was diagnosed as cervical spinal cord infarction.
- The infarction was potentially caused by a steal phenomenon, where the anterior spinal artery supplied the middle cerebral artery via the posterior communicating artery.
- Local ischemia due to cervical spondylosis was also considered a contributing factor.
Implications:
- This case highlights an unusual mechanism for spinal cord infarction.
- Understanding these complex vascular dynamics is crucial for diagnosing and treating similar neurological deficits.
- The findings emphasize the interconnectedness of cerebral and spinal cord blood supply.
Abstract:
We report a 68-year-old male patient with right hemiparesis caused by cervical spinal cord infarction. Cerebral angiography revealed right internal carotid artery occlusion. The blood flow of right middle cerebral artery was fed by the basilar artery via right posterior communicating artery. In this case, the upper cervical spinal cord infarction might be induced by steal phenomenon of anterior spinal artery to the middle cerebral artery via posterior communicating artery in addition to the local ischemia by cervical spondylosis.
