Punctural Percutaneous Image-Guided Cryoablation for Pain Relief in Bone Metastases

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