Efficacy and safety of C-arm computed tomography-guided microwave ablation with percutaneous osteoplasty for flat bone metastases

Figure 1 Schematic workflow diagram for this study. VAS: Visual analog scale.

Figure 2 Changes in indexes before and after the procedure. A: Visual analog scale before and after the procedure; B: Oswestry disability index; C: Quality of life. VAS: Visual analog scale; ODI: Oswestry disability index; QOL: Quality of life. ^aP < 0.01.

Figure 3 Changes in the lesion before and after the procedure in a patient with lung cancer and left 7^th rib metastasis. A and B: Magnetic resonance imaging (MRI) showing a metastatic tumor in the left 7^th rib, with the largest diameter measuring 53 cm; C: C-arm computed tomography (CT) reconstruction showing the puncture path of the bone puncture needle; D: The microwave ablation needle reaches the lesion for ablation treatment; E: C-arm CT reconstruction showing the distribution of bone cement; F: Three-dimensional reconstruction of C-arm CT showing the distribution of bone cement; G and H: Follow-up MRI at 3 months post-procedure showing that most of the target lesion area does not exhibit significant enhancement, with the largest diameter measuring 53 cm.
