Computer-assisted neuroendoscopy (CANE) enhances surgical navigation for ventricular system disorders. This technology improves trajectory planning and lesion localization, increasing safety and efficiency in neuroendoscopic procedures.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Endoscopy

Background:

  • Neuroendoscopy is increasingly used for diagnosing and treating ventricular system disorders.
  • Navigating the ventricular system with a ventriculoscope can be challenging due to abnormal anatomy or small ventricles.
  • Accurate endoscope localization is crucial for enhancing safety and effectiveness.

Purpose of the Study:

  • To evaluate the adaptation and utility of an image-guided stereotactic wand for rigid neuroendoscopes.
  • To assess the effectiveness of computer-assisted neuroendoscopy (CANE) in improving navigation and localization during ventriculoscopy.

Main Methods:

  • Adapted an image-guided stereotactic wand to a rigid neuroendoscope, creating the CANE system.
  • Visualized the ventriculoscope tip position and orientation in real-time using pre-operative neuroimaging.

  • Utilized computer guidance during ventricular access to minimize uncertainty.

    • Main Results:

    • The CANE system was used in eleven neuroendoscopic procedures.
    • Ten out of eleven patients showed improvement after surgery.
    • Early results indicate CANE aids in trajectory planning, navigation, and localization of pathologies.

    Conclusions:

    • Computer-assisted neuroendoscopy (CANE) can improve the safety and efficiency of neuroendoscopic procedures.
    • Real-time correlation of endoscope tip location with intraoperative imaging enhances surgical outcomes.
    • While not always essential, CANE offers significant benefits for complex neuroendoscopic cases.
