Abstract:
Objective To discuss the clinical efficacy of microwave ablation(MWA)combined with percutaneous vertebroplasty(PVP),radiofrequency ablation(RFA)combined with PVP,and simple PVP in the treatment of vertebral metastatic tumors.Methods A total of 65 patients with vertebral metastatic tumors,who were admitted to the Northern Jiangsu People's Hospital of China to receive treatment from January 2019 to June 2023,were enrolled in this study.The patients were divided into MWA plus PVP group(M+P group,n=25,27 diseased vertebral bodies in total),RFA plus PVP group(R+P group,n=20,23 diseased vertebral bodies in total),and simple PVP group(P group,n=20,24 diseased vertebral bodies in total).Visual analog scale(VAS)score was used to assess the preoperative pain degree and the postoperative relief degree.Bone cement distribution and leakage at one week after surgery were evaluated.Results Successful operation was accomplished in all of the patients.No serious procedure-related complications occurred in all the patients of three groups.In R+P group,P group and M+P group,the preoperative mean VAS scores were(8.48±0.80)points,(8.57±0.98)points and(8.20±1.00)points respectively;the differences among the three groups were not statistically significant(P>0.05).One week after operation,the pain was significantly relieved in all the patients of three groups;the mean VAS scores in R+P group,P group and M+P group were(4.10±0.85)points,(3.17±0.93)points and(2.44±1.23)points respectively,and the reduction in VAS score was most pronounced in M+P group(P<0.05).Six months after operation;the mean VAS scores in R+P group,P group and M+P group were(1.87±0.84)points,(4.60±1.09)points and(1.48±0.71)points respectively;and the reduction in VAS score was most pronounced in the M+P group(P<0.05).The used amount of bone cement in M+P group,R+P group and P group was(7.54±1.44)mL,(5.48±1.12)mL and(4.59±1.56)mL respectively,the difference among the three groups was statistically significant(P<0.05).The vascular leakage rate(34.8%)and non-vascular leakage rate(52.2%)in P group were remarkably higher than those in R+P group and in M+P group(P<0.05).No statistically significant difference in the rate of cement leakage existed between R+P group and M+P group(P>0.05).Conclusion For the treatment of vertebral metastases,MW A plus PVP is superior to RFA plus PVP in pain relief rate.
