[Postpartum chronic subdural hematoma following spinal anesthesia: case report].

Chronic subdural hematoma is a rare complication of epidural anesthesia. This report describes the case of a 34-year-old woman who presented with postpartum headache after she received epidural anesthesia for labor pain. The anesthesiologist's record did not show any anesthesia-related complication. Two days after the delivery (on day 2), the patient complained of headache. Postdural puncture headache was diagnosed, so she was administered analgesics, hydration therapy, and bed rest. On day 4, she reported a slight improvement and was discharged. The postural headache persisted even on day 7 after delivery. During the conservative treatment, she had suffered a mild head trauma. On day 13, she started to feel a non-postural and severe throbbing headache. On day 24, she was referred to our department. Bilateral chronic subdural hematoma was confirmed by a computed tomography scan. Physical examination revealed only mild right hemiparesis. Left burr hole trepanation was performed and this was followed by uneventful postoperative course. Right chronic subdural hematoma was managed by conservative treatment, and it completely recovered after 4 weeks. Chronic subdural hematoma should be considered when postpartum patients who have received epidural anesthesia present with mild to severe, persistent, and non-postural headache.
