Intraoperative fiber-optic endoscopy for ventricular catheter insertion.

Area of Science:

• Neurosurgery
• Medical Devices
• Patient Outcomes

Background:

• Ventricular catheter placement is crucial for treating hydrocephalus.
• Inaccurate catheter positioning is a common complication in neurosurgery.
• Current conventional methods have limitations in achieving optimal intraventricular placement.

Purpose of the Study:

• To compare the accuracy of endoscopic versus conventional ventricular catheter placement in adult patients.
• To evaluate the effectiveness of endoscopic guidance in achieving precise catheter tip positioning.
• To determine if endoscopic placement offers superior accuracy over traditional techniques.

Main Methods:

• Retrospective analysis of 37 patients undergoing endoscopic ventriculo-peritoneal shunt (VPS) insertion and 40 patients undergoing conventional VPS insertion.
• Development of a grading system (zones V1-V5 intraventricularly, A-C intraparenchymally) to assess catheter tip accuracy.
• Postoperative scan analysis to grade the accuracy of ventricular catheter placement.

Main Results:

• 76% of endoscopic catheters were in the optimal zone V1, with 100% in zones V1-V3.
• No endoscopic catheters were placed intraparenchymally or in suboptimal zones (V4-V5).
• Conventional placement resulted in 38% in zone V1, 53% in zones V1-3, and 15% intraparenchymally, with statistically significant differences favoring endoscopic guidance (p<0.001).

Conclusions:

• Endoscopic ventricular catheter placement offers significantly improved accuracy compared to conventional techniques.
• This neurosurgical approach enhances the precision of catheter tip positioning.
• Endoscopic guidance is a valuable tool for optimizing outcomes in ventriculo-peritoneal shunt surgery.
