Abstract:
Introduction: Microvascular decompression (MVD) is an established procedure for treating Trigeminal Neuralgia and Hemifacial Spasm. Postoperative CSF leakage is still a common complication after MVD.Material and Methods: We did a retrospective study of 134 patients who underwent microvascular decompression, mainly for Trigeminal Neuralgia and Hemifacial Spasm in our unit. All patients had an apparently watertight repair of the dura at the end of the operation done by our technique using Duraguard ® and Histacryl® glue.Results: Of the 134 patients, 129 (96.2%) had no postoperative CSF leakage. Only five (3.7%) of the patients experienced postoperative CSF leak.Conclusion: We conclude that dural repair using the described technique, with a dural substitute (Duraguard) and Histacryl glue is safe and effective in preventing postoperative CSF leakage following MVD.
Insights
This study shows that using Duraguard and Histacryl glue for dural repair after microvascular decompression (MVD) significantly reduces cerebrospinal fluid (CSF) leakage. This technique is effective in preventing this common complication.
Area of Science:
- Neurosurgery
- Neurology
Background:
- Microvascular decompression (MVD) is a standard treatment for Trigeminal Neuralgia and Hemifacial Spasm.
- Postoperative cerebrospinal fluid (CSF) leakage remains a frequent complication following MVD procedures.
Purpose of the Study:
- To evaluate the efficacy of a specific dural repair technique in preventing postoperative CSF leakage after MVD.
Main Methods:
- A retrospective study of 134 patients undergoing MVD.
- Dural repair was performed using Duraguard® (dural substitute) and Histacryl® glue.
- The technique aimed for an apparently watertight dural closure.
Main Results:
- A low incidence of postoperative CSF leakage was observed (3.7%).
- Out of 134 patients, only 5 experienced CSF leak.
- The vast majority (96.2%) of patients had no CSF leakage.
Conclusions:
- Dural repair utilizing Duraguard and Histacryl glue is a safe and effective method.
- This technique significantly minimizes the risk of CSF leakage after MVD.
- The described approach offers a reliable solution for preventing a common MVD complication.
