Ⅰ.はじめに
外傷性硬膜外血腫の出血源の大部分は硬膜動脈が頭蓋骨々折線と交叉する部にあり,この血管の破綻が脳血管撮影上,まれに造影剤の血管外漏出,いわゆるextravasationとして認められることがある.このextravasationの硬膜外血腫診断上の意義と病態については,今までにいくつかの検討がなされているが,多くは数例の報告にとどまっている.われわれはここに自験例20例について,その臨床的意義を手術適応との関連を中心に考察した.
During the last 17 years since 1958, 108 cases with traumatic epidural hematomas were treated m our clinics, and the extravasation from the middle meningeal artery was observed in 20 cases (18%) out of them. The clinical significance of the extravasation will be discussed in association with the indication of surgical intervention.
Common carotid angiographies were performed in all of 20 cases, and selective external carotid angiographies were also performed in 2 of them. The time interval from the injury to the angiographical confirmation of extravasation ranged from an hour to ten clays.
