Navigation-Assisted Ventriculoperitoneal Shunt Placement in Pediatric Hydrocephalus: Improved Catheter Positioning...

Area of Science:

• Neurosurgery
• Pediatric Surgery
• Medical Technology

Background:

• Hydrocephalus is a common neurological condition in children requiring surgical intervention.
• Ventriculoperitoneal (VP) shunt placement is a standard treatment for pediatric hydrocephalus.
• Optimizing shunt placement is crucial for effective treatment and minimizing complications.

Purpose of the Study:

• To compare the clinical outcomes of navigation-assisted versus conventional (freehand) ventriculoperitoneal shunt placement in pediatric hydrocephalus.
• To evaluate the impact of navigation technology on catheter tip position, revision rates, and length of hospital stay.

Main Methods:

• Retrospective review of 164 pediatric patients (<18 years) undergoing VP shunt placement (2015-2023).
• Comparison between navigation-assisted (n=48) and conventional (n=116) techniques.
• Assessment of catheter tip position (Yim classification), revision rates, infection, complications, and hospital stay.

Main Results:

• Navigation-assisted placement showed a significantly higher optimal catheter placement rate (81.25% vs. 60.34%).
• The revision rate was significantly lower in the navigation-assisted group (16.67% vs. 38.79%).
• Navigation-assisted surgery resulted in a shorter mean hospital stay (7.85 vs. 10.20 days).

Conclusions:

• Navigation-assisted VP shunt placement in pediatric hydrocephalus is linked to superior catheter positioning and reduced need for revisions.
• The technique is associated with a shorter hospital stay.
• Infection and overall complication rates were similar between the groups, suggesting surgical technique does not influence these outcomes.
