A Unique Approach to Neurosurgical Wound Closure With Porcine Urinary Bladder Matrix: An Illustrative Case Series

Le résumé fourni par la source

INTRODUCTION: PUBM is a non-synthetic, completely resorbable xenograft product with a myriad of uses, including management of burns, acute and chronic wounds, soft tissue reinforcement, and hernia repair. The material is available in both powder and sheet forms which allows for excellent coverage of irregularly shaped wounds. CASE REPORT: The authors present 2 challenging neurosurgical wound cases. The first case is a large thoracolumbar wound secondary to a laminectomy complicated by a high output CSF fistula and dermal dehiscence. The second case is a deep postoperative surgical site infection in the setting of a large amount of surgical hardware. Both cases were successfully managed to complete wound healing with PUBM. CONCLUSION: Neurosurgical wounds can be technically challenging and difficult to manage. CSF fistulas lack evidence for standard treatment strategy, making complications and chronic wounds more likely. The application of PUBM in the closure of neurosurgical wounds has not been thoroughly studied and may lead to improved wound closure.
