Abstract
Background context Lumbar radiculopathy after lumbar spine surgery is an alerting sign usually caused by either a recurrent disc herniation or epidural hematoma. However, pressure on a spinal nerve root may also be exerted by a retained piece of Surgicel used to achieve hemostasis during lumbar spine surgical procedures. Purpose To describe a case of lumbar radiculopathy that was caused by a piece of Surgicel left in the spinal canal after operation for lumbar disc herniation. Study setting A case report of a retained piece of Surgicel being the cause of S1 radiculopathy. Methods Patient interview, medical records, imaging studies, and literature review. Results A 29-year-old man developed acute left S1 radiculopathy after a successful hemilaminectomy and discectomy operation for a L5–S1 disc herniation. In the magnetic resonance imaging studies that were performed, a postoperative hematoma could not be excluded and a reoperation revealed compression from Surgicel that was used for hemostasis. The patient was free of symptoms after reoperation. Conclusions This case depicts the difficulty in distinguishing—by means of magnetic resonance imaging—nerve root compression caused by a postoperative hematoma and a recurrent disc herniation, from that caused by a retained Surgicel. Therefore, hemostatic agents should be meticulously used in spine surgery.
