Summary
This study presents a computer-interactive volumetric stereotactic system for brain lesion resection. The carbon dioxide laser enhances deep lesion removal, offering precision and hemostasis.
Area of Science:
- Neurosurgery
- Medical Technology
- Image-Guided Surgery
Background:
- Computer-interactive volumetric stereotactic systems enable precise surgical interventions.
- Resection of intracranial lesions, especially deep-seated ones, presents significant surgical challenges.
Purpose of the Study:
- To describe the development and clinical application of a computer-interactive volumetric stereotactic system.
- To evaluate the efficacy and safety of using a carbon dioxide laser with this system for intracranial lesion resection.
Main Methods:
- Development of a computer-interactive volumetric stereotactic system integrating CT/MRI data.
- Utilizing a carbon dioxide laser for tissue resection within the stereotactic framework.
- Detailed discussion of data acquisition, surgical planning, and interactive stereotactic surgery.
- Clinical experience documented across 500 consecutive cases.
Main Results:
- The carbon dioxide laser proved advantageous for deep-seated lesions due to convenience, hemostasis, and precision.
- The system demonstrated overall morbidity of 7% and mortality of 1% in 500 cases.
- The technique was most beneficial for resecting histologically circumscribed intra-axial lesions.
Conclusions:
- Computer-interactive volumetric stereotactic systems, particularly with CO2 laser integration, offer a safe and effective method for intracranial lesion resection.
- This approach provides significant benefits for precise removal of deep-seated and circumscribed intra-axial tumors.
