PTFE-fascia patch inlay method for the anterior approach for cervical intradural spinal lesion

STUDY DESIGN: A new method for prevention of cerebrospinal fluid leakage was studied. OBJECTIVE: To prevent cerebrospinal fluid leakage, we developed a polytetrafluoroethylene fascia patch inlay method. BACKGROUND: One of the major risks of the anterior approach for intra-dural spinal cord lesions is the cerebrospinal fluid leakage. METHODS: A small hemangioblastoma located on the ventral side of the cervical cord was resected with an anterior approach. The dural closure was performed using this polytetrafluoroethylene fascia patch inlay method. RESULTS: The patient had a satisfactory clinical course with no cerebrospinal fluid leakage. CONCLUSION: This polytetrafluoroethylene fascia patch inlay method is very effective. This method may provide both prevention of CSF leakage and future spinal cord adhesion to the dura.
