Summary
Endoscopic intraventricular procedures offer a less invasive option for deep brain lesions. While complete tumor removal is challenging, biopsies enable diagnosis in most cases.
Area of Science:
- Neurosurgery
- Minimally Invasive Procedures
Background:
- Endoscopy is a growing alternative to open surgery for intraventricular lesions.
- Deeply located lesions pose challenges for traditional microsurgery.
- Some intraventricular tumors do not necessitate aggressive treatment and may be associated with hydrocephalus.
Purpose of the Study:
- To evaluate the efficacy and approach for endoscopic intraventricular procedures.
- To determine optimal endoscopic trajectories based on lesion location and ventricular size.
Main Methods:
- Retrospective analysis of 32 patients undergoing 33 endoscopic procedures (2006-2011).
- Lesions classified by location for tailored endoscopic trajectory planning.
- Procedures utilized rigid/flexible endoscopes via precoronal or supraorbital approaches, often with neuronavigation.
Main Results:
- 33 procedures performed: 27 precoronal, 6 supraorbital.
- Complete lesion excision achieved in only 3 cases.
- Biopsies were performed in the majority of cases.
Conclusions:
- Endoscopic approach for intraventricular lesions requires tailoring to lesion location and ventricular size.
- Complete excision is often not feasible, but endoscopic biopsy is highly effective for diagnosis.
