    This multicenter retrospective cohort study evaluated prophylactic epidural blood patch (PEBP) in patients with refractory cancer pain undergoing IDDS implantation.

  • 2

    PEBP was associated with lower rates of moderate-to-severe postural headache syndrome and exploratory imaging-confirmed CSF leakage compared to conservative management.

  • 3

    The absolute risk reduction for moderate-to-severe postural headache syndrome was 19.23%, with a number needed to treat of approximately 5.

  • 4

    Minor adverse events occurred in 11.54% of PEBP patients, and no clinically evident neuraxial seeding was observed during short-term follow-up.

  • 5

    The study suggests further prospective evaluation of PEBP in selected patients, as current guidelines may not adequately address the RCP population.
