Abstract
INTRODUCTION
Treatment of metastatic vertebral fractures without neural compression is performed with percutaneous cementation techniques. The increase in intratumoral pressure by these techniques can send tumor cells into the bloodstream. To prevent this dissemination and improve pain treatment, ablation techniques have been introduced that would allow the creation of a cavity in the tumor prior to cementation or directly necrosing the metastasis when its size is small.
MATERIAL
We present the experience with ablation of two hospitals and two different ablation techniques. The first group used radiofrequency ablation (A) in 14 patients (26 vertebrae), 4 of whom underwent vertebral arthrodesis. The second group used microwave ablation (B) in 93 patients (129 lesions) without associated vertebral instrumentation.
RESULTS
In group A pain improvement in VAS was 7.7-2.6 at 6 weeks. There were no complications derived from the ablation. In most cases cementation was associated. In the group B pain improvement in VAS went from 6.8 to 1.7 at 6 weeks. Cementation was associated in all cases. There were no complications derived from the ablation.
CONCLUSION
The association of ablation techniques with vertebral cementation is a safe technique that significantly improves the patient's pain and can help control the disease.
