外傷性遅発性脳内血腫の臨床像

Traumatic Delayed Intracerebral Hematoma:Clinical aspects

I．はじめに

　外傷性頭蓋内疾患はcomputerized tomography（以降X-CT）の出現後，迅速な診断により良好な結果が得られるようになってきている^32）．一方CTの易反復性により外傷性遅発性脳内血腫が再認識され，再び新たな問題として提起されてきた^{8,10,13,15,17,24,28）}．われわれは，少数ではあるが，過去の症例から外傷性遅発性脳内血腫の臨床上の特徴，治療結果を検討し，以下の結果を得たので報告した．

In order to seek the occasion and the management oftraumatic delayed intracerebral hematoma, we selected17 cases (4.2%) of traumatic delayed intracerebralhematoma (secondary lesion) from 401 cases of headinjury, and compared them with other 11 acute trau-matic intracranial multiple lesion (immediate lesion).The age ranged from 15 to 78 (except for a newbornhit on the cranium by his mother) and the averagewas 49 in secondary lesion and 58 in immediate le-sion. Sex destribution, 15 males and 2 females insecondary lesion, and 10 males and 1 female in im-mediate lesion.
