Area of Science:
- Neurosurgery
- Medical Technology
- Neuropathology
Background:
- Transition from frame-based to frameless stereotactic biopsy systems.
- Introduction of the BrainLAB® VarioGuide neuronavigation system for improved brain biopsy procedures.
Purpose of the Study:
- To evaluate the effectiveness and safety of the frameless BrainLAB® VarioGuide system for brain biopsies.
- To analyze the diagnostic yield and procedural efficiency of the new neuronavigation tool.
Main Methods:
- Retrospective analysis of the first 20 consecutive brain biopsy procedures using the BrainLAB® VarioGuide system.
- Preoperative planning utilizing CT or MRI data.
- Surgical procedures guided by frameless neuronavigation, with intraoperative neuropathological examination.
Main Results:
- Successful harvesting of definitive pathological tissue in 18 out of 20 cases.
- Mean operation time of 49 minutes, with system setup taking 5-10 minutes.
- No adverse events reported during or after the procedures.
Conclusions:
- The frameless BrainLAB® VarioGuide system is an effective and safe tool for brain biopsies.
- The system facilitates efficient targeting and achieves a high diagnostic success rate.
- Neuronavigation significantly enhances the accuracy and safety of intracranial biopsies.
