Summary
Radiofrequency ablation (RFA) and vertebroplasty (VP) for spinal tumors are improved with intraoperative computed tomography (iCT) navigation. This 3D navigation enhances probe accuracy and reduces radiation exposure for medical staff.
Area of Science:
- Oncology
- Neurosurgery
- Radiology
Background:
- Accurate radiofrequency ablation (RFA) probe placement for spinal tumors is challenging due to lesion accessibility and radiation exposure.
- Vertebroplasty (VP) procedures also present positioning difficulties.
Purpose of the Study:
- To describe the workflow of combining RFA and VP for spinal metastasis using intraoperative computed tomography (iCT) and 3D navigation.
- To evaluate the effectiveness of this combined approach in improving probe accuracy and reducing radiation dose.
Main Methods:
- Utilized intraoperative computed tomography (iCT) for real-time imaging.
- Implemented 3D navigation systems for precise RFA probe placement.
- Integrated vertebroplasty (VP) following RFA.
Main Results:
- Achieved successful combination of RFA and VP using iCT-based navigation.
- Demonstrated optimal probe positioning through 3D navigation.
- Reported a reduction in radiation exposure for medical staff.
Conclusions:
- iCT-based navigation enables successful combined RFA and VP for spinal metastasis.
- 3D navigation significantly improves probe accuracy in RFA procedures.
- This approach effectively reduces radiation exposure for healthcare professionals.
