Cerebrospinal fluid fistula after microvascular decompression for trigeminal neuralgia
see Microvascular decompression complications.
Current treatments comprise reducing cerebrospinal fluid pressure by continuous lumbar drainage or repeated spinal taps and administering antibiotics to prevent infections 1). Failure of these treatments finally requires additional surgical intervention. Even after these treatments, fatal situations, such as pseudomeningocele, meningitis, and abscess formation, may complicate the postoperative course and lead to permanent deficits.
To prevent Cerebrospinal fluid fistula leakage after MVD, it has been highly emphasized by Peter J. Jannetta to ensure Water-tight dural closure 2).
Additionally, primary dural closure (primary reapproximation and suturing of the dural edges) is the best seal without the introduction of autologous grafts of fat or artificial dural substitutes 3)
