Percutaneous image-guided cryoablation (PICA) in relieve pain from metastatic bone disease was performed in 24 patients. The cryoprobes were navigated and the ice sphere was monitored using computed tomography. Each patient, depending on the volume of the lesion, underwent from one to four ablations. Pain assessment was performed using a numerical rank scale. A decrease in the pain index after PICA was from 4.1±0.8 points to 1.3±0.5 points. The duration of analgesic affect correlated with local control of the tumor. A later postoperative complication was noted in one case in the form of a bone fracture in the ablation zone. Further study of the effectiveness of this technology is necessary by analyzing larger samples and comparing them with the results of treatment with other methods of local exposure.
