Chronic subdural Hematomas: The Crucial Role of Eosinophils In The Lifecycle, Radiographic Architecture, And Risk Of Recurrence

Video Transcription

Video Summary

In this video, Ben Davidson, a fourth-year neurosurgery resident at the University of Toronto, discusses the crucial role of eosinophils in chronic subdural hematomas (SDH). Chronic SDH is a common neurosurgical condition, particularly in the elderly population. The pathogenesis of chronic SDH involves inflammation, angiogenesis, and hyperfibrolysis. Davidson explains that eosinophils, although normally not found in the brain, are present in approximately 40-60% of chronic SDH cases. He discusses how the presence of eosinophils can be visualized through CT scans and correlated with different stages of the disease. The study found that a dense eosinophilic infiltrate is associated with a lower risk of recurrence requiring reoperation. Further research is being conducted to validate these findings and explore alternative outcome measures. The talk was supported by the Codman Fellowship in Neurotrauma and Critical Care. No other credits are mentioned.
