Insights
Surgical revascularization for common carotid artery occlusion effectively treated progressive stroke symptoms. A novel aortic arch to internal carotid artery shunt restored cerebral perfusion, resolving neurological deficits.
Area of Science:
- Vascular Surgery
- Neurology
- Diagnostic Imaging
Background:
- Progressive neurological symptoms in a 45-year-old man were investigated.
- Standard diagnostic imaging revealed complex cerebrovascular pathology.
Observation:
- Duplex sonography identified left common carotid artery occlusion with retrograde flow and pseudovenous flow in the internal carotid artery.
- Transcranial duplex sonography demonstrated pseudovenous flow in the ipsilateral middle cerebral artery, indicating compromised intracranial collateral circulation.
Findings:
- Operative revascularization using a primary shunt from the aortic arch to the internal carotid artery was performed.
- Post-revascularization, perfusion of the left middle cerebral artery normalized, and neurological symptoms resolved.
Implications:
- Revascularization for common carotid artery occlusion presenting with progressive stroke is a viable therapeutic option.
- The described surgical technique and shunt placement ensure adequate cerebral perfusion in complex cases.
Abstract:
We report on the case of a 45-year-old man with stroke and progressive neurological symptoms. Duplex sonography showed an occlusion of the left common carotid artery as well as an open internal carotid artery due to retrograde flow from the external carotid artery into the internal carotid artery with pseudovenous flow. Transcranial duplex sonography showed a pseudovenous flow in the ipsilateral middle cerebral artery, because of insufficient intracranial collateralisation. During operative revascularisation, a primary shunt from the aortic arch to the internal carotid artery was necessary. After revascularisation, perfusion of the left middle cerebral artery was normal and the neurological symptoms abated. Revascularisation of a common carotid artery occlusion in case of progressive stroke may be indicated. The central position of the shunt and the surgical procedure described provide sufficient cerebral perfusion.
