Prophylactic Fibrin Glue Application for Immediate Management of Dural Puncture during Spinal Cord Stimulation Lead Placement: a Simple and Effective Technique.

Abstract

Background: Accidental dural puncture during epidural lead insertion for Spinal Cord Stimulation (SCS) is a recognized surgical complication that may lead to cerebrospinal fluid (CSF) leakage and subsequent postdural puncture headache (PDPH). The optimal technical approach to prevent CSF leakage remains controversial. This study aimed to evaluate a simple and efficient intraoperative technique for managing accidental dural puncture during SCS lead placement.

Materials and methods: A retrospective review was conducted of the medical records and imaging studies of all patients who underwent SCS procedures between January 2020 and April 2024. Signs or symptoms associated with dural puncture were recorded, including subcutaneous fluid collections, pseudomeningocele formation, PDPH, wound infection, and meningitis.

Results: Among 107 patients who underwent SCS implantation, involving a total of 194 lead insertions, 4 cases (3.7%) of intraoperative CSF leakage due to iatrogenic dural puncture were identified. Each case was managed by injecting fibrin glue through the introducer needle into the epidural space, directly over the dural lesion.

Conclusions: Prophylactic application of fibrin glue following dural puncture appears to be highly effective in sealing the damage and preventing CSF leakage. This technique offers a valuable intraoperative solution for surgeons to immediately address dural injuries during SCS lead placement, potentially minimizing postoperative complications and improving patient outcomes.
