Effectiveness of Gelatin-Thrombin Matrix Sealants (Floseal®) on Postoperative Spinal Epidural Hematoma during Single-Level Lumbar Decompression Using Biportal Endoscopic Spine Surgery: Clinical and Magnetic Resonance Image Study

<div>A patient who underwent BESS decompression for L2–3 spinal stenosis (a) Preoperative T2-weighted MRI showing bilateral recess stenosis. (b) Postoperative T2-weighted MRI showing grade II PSEH. (c) Follow-up MRI 6 months after surgery showing resorption of the PSEH with epidural fibrosis causing right lateral recess restenosis. (BESS: biportal endoscopic spine surgery, MRI: magnetic resonance image, PSEH: postoperative spinal epidural hematoma).</div>
