Summary
A novel neurosurgical navigator integrated with ultrasound provides accurate guidance for treating intracerebral lesions like astrocytomas and hematomas. This system enhances surgical precision and procedural outcomes in complex brain surgeries.
Area of Science:
- Neurosurgery
- Medical Imaging
- Surgical Navigation
Background:
- Intracerebral lesions require precise surgical intervention.
- Existing neuronavigation systems can be enhanced with advanced features.
- Ultrasound integration offers real-time intraoperative guidance.
Purpose of the Study:
- To describe a unique neurosurgical navigator system.
- To present a preliminary case series of intracerebral lesions managed with the system.
- To evaluate the system's accuracy and utility in neurosurgical procedures.
Main Methods:
- Development of a neuronavigation system with interactive 3D reconstructions (CT/MRI) and intraoperative ultrasound.
- Utilized a common axis principle for aligning instruments (pointer, biopsy/endoscope guides, ultrasound transducer, microscope).
- Applied the system in seven cases: five low-grade astrocytomas, one hematoma, one cyst, with voice control features.
Main Results:
- The system successfully guided biopsies, hematoma drainage, and cyst fenestration.
- Intraoperative ultrasound verified neuronavigator accuracy and procedural results.
- Voice control streamlined system calibration and operation, freeing the surgeon's hands.
Conclusions:
- The developed neurosurgical navigator, combined with ultrasound, offers a versatile and accurate tool for managing diverse intracerebral lesions.
- The system's integration of imaging, navigation, and instrument guidance improves surgical precision.
- This technology holds promise for advancing minimally invasive neurosurgical techniques.
