Two Cases of Spontaneous Extradural Hematoma on the Lumbar Spine: Comparison of the Operative Results by the Delay Before Surgery

ABSTRACT

Two surgically treated cases of spontaneous spinal epidural hematoma are reported. We compared the operative results between these cases, and could conclude without difficulty the early diagnosis and operation were important in prognosis. A patient who had endured shorter interval, around 24 hours, between the beginning of paraplegia and surgical decompression recovered earlier, not longer than one month, than the other patient who had been operated on with five days of interval. This patient did not recover well even two months after the operation.
