Clinical Application of Percutaneous Vertebroplasty in the Treatment of Vertebral Tumour

Objective:To investigate the clinical efficacy of percutaneous vertebroplasty (PVP) in the treatment of vertebral tumour.Methods:Of 32 cases with 44 vertebral tumors including metastatic tumor (26 patients,36 vertebral bodies involved),myeloma (2 patients,4 vertebral bodies),hemangioma (4 patients,4 vertebral bodies),percutaneous puncture of vertebral lesions were performed under C-arm fluoroscopy and bone cement was injected.The visual analogue scale point (VAS) (10 point scale) were recorded before and 24 hours,one week and one month after vertebroplasty respectively.Result of pain relief and complications were observed.Results:100% success rate of PVP was obtained.Complete relief (CR) was assessed in 21 patients,partial relief (PR) in 21 patients,mild relief (MR) in 2 patients and no pain relief in 1 patient 30 days after operation.The total rate of pain relief (CR+PR) was 90.6% (29 /32 patients).There are significant differences among the scores of VAS with different time points (before operation;24h,1w,1m after operation) (P0.05).After PVP,apart from asymptomatic bone cement leakage around 8 vertebral bodies,no new vertebral fracture as well as aggravation of vertebral body compression was revealed in all patients during the follow-up of 1~12 monthes.No major complications occurred.Conclusion:The clinical effect of percutaneous vertebroplasty for vertebral tumour is safe and satisfactory.
