Abstract:
Spinal anesthesia (SA) has been utilized for lumbar surgical procedures; however, postdural puncture headache (PDPH) and subdural hemorrhage (SDH) are potential consequences. We present the case of a 76-year-old with progressive neurogenic claudication secondary to lumbar spinal stenosis who received SA for a 2-level lumbar posterior decompression. After decompression, the site of dural puncture from a 24-gauge Sprotte spinal needle was identified. Our intraoperative image demonstrates the submillimeter dural defect that can potentially engender complications as significant as PDPH and/or SDH. We recommend searching for, and preemptively sealing, the dural puncture site when SA is used for lumbar spine surgery.
