Subependymal hemorrhage following drainage of chronic subdural hematoma: Probable causative mechanisms and prevention strategies

Chronic subdural hematoma (cSDH) is a common clinical entity treated by neurosurgeons with good cure rates. Recurrence of the hematoma and failure of the brain to re-expand are commonly observed complications following surgery for cSDH. An intracerebral or intraventricular hemorrhage following evacuation of cSDH is very rarely observed, albeit with devastating consequences. We report the finding of a subependymal hemorrhage after evacuation of a cSDH and discuss the probable causative mechanisms underlying this rare occurrence and the prevention strategies to avoid it.
