This study presents a simple, step-by-step neuronavigation protocol for the LOTTA ventriculoscope, simplifying both ventricular access and intraventricular procedures. The method enhances neuroendoscopy by avoiding rigid fixation and bulky equipment.
Area of Science:
- Neurosurgery
- Medical Devices
- Surgical Navigation
Background:
- Neuronavigation protocols for ventriculoscopy vary significantly with different equipment.
- Existing literature lacks detailed navigation guidelines for specific ventriculoscope models.
- This necessitates the development of standardized, user-friendly protocols for effective neuroendoscopic procedures.
Purpose of the Study:
- To describe a step-by-step method for neuronavigation during ventriculoscopy using the LOTTA ventriculoscope.
- To provide a detailed protocol for both extraventricular and intraventricular navigation phases.
- To simplify complex neuroendoscopic surgeries through an accessible navigation technique.
Main Methods:
- Utilized a LOTTA ventriculoscope with an electromagnetic stylet (Medtronic S8-StealthSystem).
- Employed a 3D-printed or modified original trocar for extraventricular navigation.
- Integrated a modified pediatric nasogastric tube with the electromagnetic stylet for intraventricular navigation.
Main Results:
- The protocol is rapidly deployable, requiring less than 10 minutes for setup.
- Navigation is achieved using the electromagnetic stylet within the specialized trocars and nasogastric tube.
- The technique emphasizes achieving a blunt, bloodless ventricular approach and precise alignment of target structures.
Conclusions:
- The described protocol is straightforward to implement and eliminates the need for rigid head fixation.
- It simplifies both simple and complex neuroendoscopy procedures, leading to improved surgical outcomes.
- Continuous navigation is facilitated throughout the surgical process, enhancing safety and efficiency.
