{orange:Overview}

In a case series peer-reviewed in Pediatric Neurosurgery, researchers followed 9 pediatric hydrocephalus patients who had experienced 14 proximal shunt failures in the two years prior to ReFlow implantation. Each patient received the ReFlow® Mini Flusher and began regular flushing as part of their shunt maintenance.

Follow-up was conducted over a 2–4 year period post-implantation, with the primary endpoint being the number of proximal shunt failures requiring revision surgery.

{orange:Key Findings}

Across all 9 patients over the 2–4 year follow-up period:

• 14 proximal failures occurred in the two years before ReFlow implantation
• Only 1 proximal failure occurred in the 2–4 years following ReFlow implantation
• Caregiver compliance with the maintenance flushing protocol averaged 94% at two years, demonstrating real-world feasibility of the protocol outside clinical settings.
• Represents a substantial reduction in revision-requiring events within this cohort
• No device-related adverse events reported during the follow-up window

{orange:Clinical Implications}

For a pediatric population where shunt failure within the first year can reach 40–50%, these early results suggest that routine, noninvasive flushing may meaningfully shift the trajectory of long-term shunt management.

While these findings are from a small cohort and further study is warranted, they support the hypothesis that proactive maintenance, rather than reactive revision, may improve outcomes for children living with hydrocephalus.
