Summary
Image-guided endoscopy (IGE) enhances neurosurgery by overcoming limitations of traditional microscopes. This study demonstrates IGE
Area of Science:
- Neurosurgery
- Medical Imaging
- Endoscopy
Background:
- Traditional neuroendoscopy using operating microscopes suffers from poor stereoscopic vision and image quality.
- Limitations in current neuroendoscopic techniques hinder effective treatment of central nervous system and spinal lesions.
Purpose of the Study:
- To evaluate the feasibility and potential applications of image-guided endoscopy (IGE) in neurosurgery.
- To assess IGE's ability to overcome the visual limitations of conventional neuroendoscopic methods.
Main Methods:
- A rigid endoscope was tracked using an image-guided surgery (IGS) system, providing real-time navigational data.
- A 3D virtual representation of the endoscope's view was generated and integrated with navigational data.
- The IGE procedure was performed on 14 patients with various intracranial pathologies.
Main Results:
- The IGE procedure was successfully completed in all 14 patients without any procedure-related complications.
- Registration accuracy of the endoscope and the virtual image was found to be highly accurate compared to traditional microscopy.
- The study included patients with pituitary adenomas, temporal cavernous malformations, and unruptured aneurysms.
Conclusions:
- Image-guided endoscopy (IGE) presents significant advantages for neurosurgical and spinal endoscopic procedures.
- Advances in IGE technology hold promise for expanding its application beyond the central nervous system.
- IGE offers improved visualization and navigation, potentially enhancing surgical outcomes.
