Abstract:
Objective To discuss the technique and clinical efficacy of percutaneous vertebroplasty (PVP) in the treatment of vertebral malignant lesion.Methods PVP was performed in 13 patients (15 vertibrae) including metastasis in 11 and primary tumor in 2 cases,thoracic vertebrae involved in 6 cases and lumbar vertebrae involved in 7 cases.13 cases aged between 45 and 73,median age 59 years.Under C-arm fluoroscopic or CT monitoring,needle the puncture of the vertebral body was performed through the pedicle of vertebral arch using 11~13G,15 cm long needle.Omnipaque was injected into the vertebral body to understand the information of large drain veins,then 3~7 ml of polymethylmethacrylate (PMMA) bone cement mixture(with the ratio of powder/contrast agent as 3GA9552GA9551 )was injected.The patients were followed up for 6~12 months.Results The successful rate of puncture was 100%.76.9%(10/13) of patients get better in symptoms in 3 days after operation,pain relieved in 6 months was 69.2%(9/13),in one year was 54.5%(6/11).In followed up period,CT showed the PMMA distribution was good,the vertebral body had no compression,the patients had no serious complications.Conclusion PVP is an effective and safe method for malignant lesion of vertebral body in anti-pain,preventing the compression vertebral body and secondary paraplegia.
