RESUMO
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.

BACKGROUND: Cervical neural foraminal stenosis is a common and debilitating condition affecting people between the ages 40-60. Although it is established that MRI is the best method of scanning the neural foramen, the question remains whether there is a role for three-dimensional MRIs and whether it is possible to develop a computer-aided automated grading system to establish the degree of clinically relevant cervical foraminal stenosis. OBJECTIVE: The study's objective is to conduct a literature review of existing or recently developed automated grading systems for the cervical neural foramen, including volumetric MRI evaluations of the foramen. METHODS: A systematic search of Cochrane Library, Cochrane Clinical Trials, Ovid MEDLINE, EMBASE, CINAHL, ACM Digital Library and Institute of Electrical and Electronics Engineers (IEEE), and Web of Science was performed for reports examining automated systems and volumetric scanning foraminal stenosis published before 31.07.2021. RESULTS: 3971 articles were identified of which 8 were included in the study. The automated grading systems of the neural foramen focus largely on the lumbar spine with elements that may be applicable to the cervical spine. Although there are established studies on the automated grading of the lumbar spine, it is uncertain whether any of these are reproducible in the cervical spine. Visual grading systems for the cervical spine demonstrate good inter-reader reliability between radiologists and clinicians. CONCLUSION: The Park visual grading method shows strong inter-reader reliability across radiologists and clinicians despite the limited data on the correlation with neurological symptoms or surgical outcome. There is scope for further development of an automated grading system for cervical foraminal stenosis to improve the speed and consistency of image interpretation.
