A 5-year-old male suffered a head injury after falling from a height of 2 meters. Upon admission, five hours after the accident, he had a Glasgow Coma Scale (GCS) of 15. Brain computed tomography (CT) revealed an epidural hematoma (EDH) in the right temporoparietal area and a subdural hematoma (SDH) in the left temporal area (), as well as a skull fracture in both temporal bones. Emergency right craniotomy was performed and the EDH was evacuated. The underlying dura was loose and depressed. Intraoperative TCS applied to the right craniectomy site revealed no expansion of the left side hematoma (). The damaged meningeal artery was coagulated, dural tacking sutures were placed to prevent EDH re-accumulation, and the bone flap was repositioned.\nAfter confirming no change in the contralateral hematoma volume by postoperative brain CT immediately after surgery, the patient was admitted to the intensive care unit. After arousal, his GCS score had not changed. The patient was discharged on hospital day 13 with no definite neurological deficit.
A 51-year-old female was admitted with a head injury after a pedestrian accident. Upon admission, one hour after the accident, she had a GCS of 14. Brain CT revealed an EDH in the right temporoparietal area, SDH in the left frontal area (), and skull fracture in the right temporal and left frontal bone. Emergency right craniotomy was performed and the EDH was evacuated. Softened dura matter was found after performing craniectomy. Intraoperative TCS applied to the craniectomy site revealed volume expansion of the EDH in the left frontal area (). The bone flap was repositioned. Her vital signs were stable, and she was transported to the CT room. Brain CT confirmed the presence of a de novo EDH in the left frontal area. As a result, a second operation was performed on the left side. Her postoperative GCS score was 14, and the patient was discharged on hospital day 20 with no definite neurological deficit.
