Abstract
We report a case diagnosed with lumbar spinal stenosis who underwent reoperation for a spinal subdural hematoma (SSH) following minimally invasive lumbar decompression in the early postoperative period. This study aimed to discuss the management of this rare complication. A female patient with spinal stenosis underwent an uncomplicated left-sided, unilateral, three-level lumbar hemilaminectomy for bilateral decompression. However, six hours after surgery, she developed numbness and weakness in the right foot. An urgent lumbar MRI revealed an acute SSH at the operated levels. When paraparesis developed within minutes, the patient underwent emergency re-exploration. To our knowledge, this is the first reported case of SSH developing in the very early postoperative period. SSH is a rare complication that should be considered in patients presenting with progressive neurological deficits after spinal surgery. Prompt evacuation of the hematoma remains the most appropriate treatment.
