Summary
Neuronavigation guided endoscopic biopsy and third ventriculostomy effectively managed pineal tumors with hydrocephalus in five patients. This technique minimized brain injury and eliminated the need for further CSF diversion procedures.
Area of Science:
- Neurosurgery
- Medical Technology
Background:
- Pineal tumors with hydrocephalus present complex management challenges.
- Endoscopic procedures are increasingly used but require precise navigation.
Purpose of the Study:
- To evaluate the efficacy and safety of neuronavigation-assisted endoscopic biopsy and third ventriculostomy for pineal tumors with hydrocephalus.
- To demonstrate a minimally invasive technique for managing these complex cases.
Main Methods:
- Application of a neuronavigation system for preoperative planning of burr hole sites and trajectories.
- Real-time intraoperative monitoring of the endoscopic device using neuronavigation.
- Performance of endoscopic biopsy and third ventriculostomy in five patients with pineal tumors.
Main Results:
- Successful completion of biopsy and third ventriculostomy in all five patients.
- Mean systemic accuracy of neuronavigation registration was 1.2 mm.
- No procedure-related complications or need for subsequent CSF diversion.
Conclusions:
- Neuronavigation-guided endoscopy is a safe and effective technique for managing pineal tumors with hydrocephalus.
- This approach allows for precise targeting, minimizing brain injury.
- The technique is feasible with standard rigid endoscopes.
