“Zero mortality and minimal morbidity” for epidural hematoma is the goal of neurosurgeon. The main reason for not attainning this goal is delayed diagnosis and treatment of delayed hemorrhage, which is not found initially. During a 2 year period, 33 patients with traumatic epidural hematoma(EDH) were admitted to the neurosurgical unit of this community teaching hospital, and managed with surgical evacuation by the same neurosurgeon. The overall mortality was 6%, and 88% of the patients made a good recovery. This report concerns our experience with 12 patients who was defined as delayed epidural hematoma(delayed EDH). Early diagnosis of delayed EDH can be facilitated by close clinical observation, liberal use of CT scanning, and high clinical suspicion.
