Abstract
Introduction
This study aims to assess the effectiveness of combined procedure of cryoablation and vertebroplasty (CVT) for reduction of pain and improvement of the quality of life in patients with single painful metastatic vertebral fractures.
Methods
We retrospectively analyzed data from 23 patients with single vertebral metastasis treated with combined procedure of CVT, compared with those obtained in 23 patients treated by vertebroplasty. Pain intensity was evaluated by a visual analog scale (VAS) score administered before and 1 day, 1 week, and 1, 3, and 6 months after procedure. Quality of life was evaluated by an Oswestry Disability Index (ODI) score administered before and at 3 and 6 months after procedure.
Results
Procedural success was achieved in all patients without any complications. The VAS and ODI scores showed a reduction in both groups during follow-up (VAS score, p < 0.05 and p < 0.001, respectively; ODI score, p < 0.0001). No difference of the VAS and ODI scores were observed before treatment (p = 0.33 and 0.78, respectively). VAS score showed a difference at 1 week and 1, 3, and 6 months after treatment (p < 0.001). ODI score showed a difference at 3 and 6 months after treatment (p < 0.001).
Conclusion
Our findings suggested that combined procedure of CVT is safe and effective for pain relief in single metastatic vertebral fractures, especially when other standard palliative treatments have failed, and improves disability. Careful needle positioning and accurate fluoroscopic and CT guidance are mandatory for a complication-free treatment.
