Intervention(s)Overflow leak test Lumbar puncture is performed by the general lumbar puncture method, and 30 mL of ARTCEREB is intramedullarily injected. MRI will be taken within 1 hour after intrathecal injection. The site where the change is observed compared with the MRI image before intramedullary injection is judged to have a high possibility of leakage. After that, adverse events will be confirmed the next day and 5 days later, and the study will be terminated.

Outcome(s)

Primary OutcomeComparison of the rate at which the leak site could be identified by CT myelography images and the rate at which the leak site could be identified by the 30 mL intrathecal injection Overflow leak test
Secondary Outcome(1) Comparison of the rate at which the leak site could be identified by CT myelography images and the rate at which the leak site could be identified by the Overflow leak test (including discontinued cases) (2) Changes in MRI images before and after the Overflow leak test
