Ventricular catheter placement with a frameless neuronavigational system: a 1-year experience

Area of Science:

• Neurosurgery
• Medical Devices

Background:

• Accurate ventricular catheter placement is crucial for preventing proximal catheter failure.
• Neuronavigational systems can enhance the precision of catheter placement.

Purpose of the Study:

• To evaluate the efficacy of a frameless, electromagnetic neuronavigational system for ventricular catheter placement.
• To assess the impact of this technology on catheter failure rates and patient outcomes.

Main Methods:

• Thirty-four ventricular catheters were placed using a Medtronic electromagnetic frameless neuronavigational system.
• The study included patients aged 11 months to 79 years with various indications for catheter placement.

Main Results:

• No proximal catheter failures were reported in the study cohort.
• One infection required shunt removal; three deaths were unrelated to catheter placement.

Conclusions:

• Frameless neuronavigation ensures accurate ventricular catheter placement, significantly decreasing proximal catheter failure.
• The system's lack of rigid head fixation broadens its applicability, offering a safe and simple adjunct for optimal placement.
