지연성 외상성 뇌경막외 혈종 : Delayed Bleeding & Delayed Expansion = Delayed Post-traumatic Extradural Hematomas

다국어 초록 (Multilingual Abstract)

Delayed traumatic extradural hematoma is a new pathological dimension. Thirteen patients with delayed traumatic extradural hematoma were seen 70 treated cases of extradural hematomas for a freqency of 18.6％. The hematomas were insignificant or not present on the initial CT scanning.
All patients had a skull fracture at the site of delayed extradural hematoma formation. Ten hematomas were surgically evacuated and three were reabsorbed spontaneously. Repeated CT scanning was performed if the patient has any new focal neurological deficits or clinical status was not improved despite of minimal extradural hematoma after head injury.
Delayed extradural hematoma were classified into two gropus based on the presence of hematoma in initial CT scan : delayed bleeding type(newly formed extradual hematoma/ 4cases : 5.7％) & delayed expansion type(enlargement of initial thin hematoma/9 cases : 12.6％).
