Abstract
BACKGROUND CONTEXT: Subdural hematomas (SDHs) have been described as a rare complication from durotomy after lumbar spine surgery. In half of the reported cases, the durotomy was unnoticed intraoperatively. The most common presenting symptom was persistent headache. PURPOSE: To report a case of SDH after routine microdiscectomy and to review the literature. STUDY DESIGN: Case report and review of the literature. METHODS: Retrospective review of patient's history and imaging studies. RESULTS: A 39-year-old female underwent routine microdiscectomy for L5-S1 herniated disc. There were no complications, and no dural tear was noted. Approximately 1 week postoperatively, the patient complained of severe headaches. Imaging revealed a right intracranial chronic SDH and a lumbar pseudomeningocele. Operative exploration of her lumbar wound revealed a dural tear, which was closed primarily. The patient had subsequent resolution of her SDH. CONCLUSIONS: The authors present a case of a routine microdiscectomy complicated by delayed cerebrospinal leak causing a chronic SDH. This report illustrates the need for a comprehensive evaluation of headaches after spine surgery.
