[Acute epidural hematoma with extravasation on cerebral angiogram in an infant (author's transl)].

The authors recently operated on a boy four years of age with acute epidural hematoma showing an extravasation on the cerebral angiogram. The hematoma (hematoma volume 125 ml) was evacuated 7 hours after the head injury. The postoperative course was quite uneventful, and he was discharged a month after surgery without any neurologic deficits. The authors reviewed the literature and found 4 cases of acute epidural hematoma with extravasations in infants and children. In all cases the operative results were good. The age incidence and frequency of occurence overall for acute epidural hematomas, extravasations on cerebral angiograms and their mechanism, and the length of time from injury to operation were also discussed. It should be emphasized that, for acute epidural hematoma in infants and children, the early diagnosis and early surgery are essential to save the patients.
