  • hematoma compresses the brain tissue, various symptoms such as hypertensive intracranial pressure, consciousness disorder, progressive dementia, and hemiplegia may appear depending on the size of the hematoma. Therefore, when a chronic subdural hematoma is confirmed by imaging tests and these symptoms appear, the doctor inserts a drainage tube into the hematoma to drain it.
