Summary
The CT-guided SIRIO augmented reality navigation system significantly reduces radiation dose and procedural time during vertebral radiofrequency ablation (RTA) for bone tumors. This advanced navigation improves neuroprotection efficacy and safety without impacting pain management outcomes.
Area of Science:
- Medical Imaging and Interventional Radiology
- Neurosurgery
- Oncology
Background:
- Vertebral thermal ablation (RTA) is used for bone tumors, but procedural efficacy and neuroprotection require optimization.
- Minimally invasive techniques aim to reduce radiation exposure and procedure duration.
Purpose of the Study:
- To evaluate the impact of the CT-guided SIRIO augmented reality navigation system on RTA for vertebral tumors.
- To assess the system's effect on procedural efficacy, radiation dose, dissection time, and clinical outcomes.
Main Methods:
- A retrospective analysis compared 12 SIRIO-assisted RTA procedures with 16 non-SIRIO-assisted procedures for vertebral tumors.
- Primary outcomes included radiation dose (DLP) and epidural dissection time; secondary outcomes included technical success, complications, and pain scores (VAS).
Main Results:
- SIRIO-assisted RTA significantly reduced DLP (307.42 vs. 460.31 mGycm) and epidural dissection time (13.48 vs. 32.26 min) compared to non-assisted procedures (p < 0.001).
- Multiple regression confirmed these significant reductions.
- No significant differences were observed in pain scores at three months post-procedure between the groups.
Conclusions:
- The SIRIO augmented reality navigation system enhances neuroprotection during vertebral RTA for bone tumors.
- It effectively reduces radiation dose and procedural time, improving safety and efficacy.
- The system maintains comparable pain management outcomes, demonstrating its clinical utility.
