 A 93-year-old woman incurred a head bruise 5 days prior to presentation, and head CT revealed right subacute subdural hematoma. As she was on direct oral anti-coagulant(DOAC)treatment for non-valvular atrial fibrillation(NVAF), the DOAC administration was stopped temporarily to prevent an increase in the size of the hematoma. Dabigatran treatment was initiated after the confirmation of no change in hematoma size and the follow-up CT revealed a reduction in the hematoma. However, left upper limb paresis occurred on day 12 of dabigatran treatment and head CT revealed the onset of right chronic subdural hematoma. Emergency burr hole surgery was performed after intravenous administration of idarucizumab to neutralize the dabigatran. Her neurologic symptoms improved after the operation and no recurrence of subdural hematoma was observed even after dabigatran treatment was resumed. Dabigatran could be administered relatively safely, even for subacute intracranial hemorrhage complicated with NVAF, suggesting the possibility of the prevention of ischemic stroke. Moreover, even when intracranial hemorrhage recurred, the prompt neutralizing effect of idarucizumab, a dabigatran-specific neutralizing agent, was useful in the surgical intervention and perioperative management.
