@viz.med: A chronic subdural hematoma is a slow buildup of blood beneath the dura that can develop weeks after a head injury. As blood collects, it presses on the brain, and symptoms may appear gradually—especially in older adults or those on blood thinners. When pressure increases, doctors may perform burr hole surgery to drain the blood and relieve that pressure. #SubduralHematoma #BrainHealth #Neurosurgery #3DMedicalAnimation #MedicalAnimation #PatientEducation #Neurology
