Well either that, or "spray and pray" to fix unknown holes, but deliberately make another small, known, controlled hole that can relieve pressure and gradually be shrunk until it's shut.

The valve never really worked well, and she didn’t live long enough to determine why.

This would make things worse. The pressure has already been relieved by the original hole with subsequent loss of cerebrospinal fluid.
Post-spinal/dural puncture headache results from NOT ENOUGH CSF surrounding the spinal cord and brain as a result of its leaking out: thus, the brain sags and positions itself on the base of the skull rather than floating, with subsequent headache.
