Cerebrovascular accident, abbreviated CVA, is a common neurologic pathology. It is also known as a stroke.
General
- Very common.
- Leading cause of morbidity and mortality.
Etiologies:[1]
- Atherosclerosis of the cerebral vessels or internal carotid artery.
- Embolism.
- Hemorrhage (ruptured berry aneurysm, cerebral amyloid angiopathy).
- Tumour.
- Others.
Clinical classification:
- Hemorrhagic stroke.
- Ischemic stroke.
Gross
- Soft/mushy brain.
- Older infarcts.
- A "roof" is present - a thin submeningeal layer is preserved by the CSF.[2]
- "Roof" is absent in trauma.
- Cavity - in older infarcts.
- Multiple sclerosis does not cavitate.
- A "roof" is present - a thin submeningeal layer is preserved by the CSF.[2]
- Laminar necrosis = (thin) chalky line replaces grey mater.[3]
