[Non-operative regions extradural hematoma: a review of 5 cases].
The authors report five patients who developed non-operative regions extradural hematoma following removal of intracranial tumors (3 cases) or cystiform diseases (2 cases). 3 cases developed on the left hemicerebrum. 2 cases formed on the bilateral. 4 cases were supratentorial operations, one inferior tentorial. The causative mechanisms of hematoma formation were attributed to a rapid fall in intracranial pressure, an increased blood velocity and the patient's position during the operation. Unexplained cerebral swelling during operation or delayed post-operative recovery should be intensely investigated by CT scanning. An emergency operation is indicated when the hematoma volume is more than 30ml.
