Suction Catheter as an Endoscopic Port for Simultaneous Real-Time Neuronavigation and Neuroendoscopy: A Technical...

Area of Science:

• Neurosurgery
• Medical Devices
• Pediatric Surgery

Background:

• Neuronavigation and neuroendoscopy improve intraventricular procedure safety.
• Complex pediatric hydrocephalus presents challenges for simultaneous navigation and intervention.
• Existing endoscopic systems limit combined use of navigation, visualization, and instruments.

Purpose of the Study:

• To describe a cost-effective modification for simultaneous neuronavigation and neuroendoscopy.
• To present a novel working conduit for intraventricular procedures.
• To evaluate the efficacy of a repurposed suction catheter in pediatric hydrocephalus.

Main Methods:

• A standard 14 Fr suction catheter was modified as a working conduit.
• The modified catheter allowed simultaneous passage of a neuroendoscope and navigation/intervention tools.
• The technique was applied in an infant with congenital multiseptate hydrocephalus for septal fenestration.

Main Results:

• The modified conduit facilitated uninterrupted real-time navigation and visualization.
• Adequate working space was provided for endoscopic interventions.
• The technique eliminated the need for repeated instrument exchanges without intraoperative complications.

Conclusions:

• A modified suction catheter serves as an effective dual-channel port for intraventricular procedures.
• This technique allows simultaneous neuronavigation, neuroendoscopy, and intervention.
• The method is cost-effective and enhances safety in pediatric neurosurgery.
