What causes seizure after subdural hematoma surgery?

Seizures after subdural hematoma surgery can occur due to several factors, including cortical irritation from the surgical procedure, changes in brain tissue integrity, or the presence of residual blood or fluid. Additionally, pre-existing brain conditions or complications such as infections or electrolyte imbalances may contribute to seizure activity. The risk is also influenced by the patient's age, overall health, and the extent of the hematoma or brain injury. Monitoring and management are crucial to minimize the risk of post-operative seizures.
