Summary
Simultaneous arterial and venous stroke is rare. Autopsy revealed co-existing arterial and venous infarctions, alongside arterial and venous thrombosis in three patients, highlighting potential contributing factors.
Area of Science:
- Neurology
- Pathology
- Vascular Medicine
Background:
- Cerebral arterial and venous thrombosis occurring simultaneously in the same individual is an exceptionally rare clinical presentation.
- Understanding the pathogenesis of combined arterial and venous cerebrovascular events is crucial for diagnosis and treatment.
Observation:
- This report details three patients who presented with stroke and, upon autopsy, were found to have co-existing arterial and venous infarctions.
- These cases demonstrated major arterial occlusions (vertebral and internal carotid arteries) coupled with thrombosis of dural sinuses and cortical veins.
Findings:
- The study highlights the co-occurrence of arterial occlusion and cerebral venous sinus thrombosis in the same patients.
- Potential contributing factors to this rare condition, including infarcted brain tissue, haemorrheological factors, and alcohol consumption, are discussed.
Implications:
- This case series expands the understanding of rare cerebrovascular pathologies involving both arterial and venous systems.
- Further research into the interplay of vascular occlusion, brain infarction, and systemic factors may elucidate the mechanisms behind these complex stroke presentations.
