特発性低髄液圧症に合併した両側性慢性硬膜下血腫の治療経験

抄録

Chronic subdural hematoma (CSDH) sometimes occurs in patients with spontaneous intracranial hypotension (SIH). Conservative therapy including bed rest and hydration, should be initially considered when the patient does not present consciousness disturbance or paralysis. However, if the patient does not get improved by conservative thera­py alone, the treatment strategies for these cases remain controversial.

We herein report two cases of bilateral CSDH concomitant with SIH, which were successfully treated by epidural blood patch (EBP) for SIH followed by burr hole evacuation for CSDH within a day. The immediate effect of EBP for SIH might cause acute elevation of intracranial pressure, sub­sequent urgent evacuation of CSDH should be prepared.
