Curative effect observation of percutaneous vetebral plasty in the treatment of spinal tumor and spinal metastatic tumor

Abstract

Objective To observe the effect of percutaneous vertebral plasty (PVP) on spinal tumor and spinal metastatic tumor.Methods Twenty-nine cases of thoracolumbar metastatic tumor and (or) multiple myeloma,with a total of 86 disease were treated by PVP surgical.The pain degree was estimated by pain classification method (VRS) on the 3th day,3 and 6 months postoperation,and the quality of life was estimated by the self-care ability of daily life (ADL) 6 months postoperation.Results The vertebral puncture were successful.Intraoperative,bone cement along the vertebral venous plexus leakage in 2 cases,injection of bone cement occurs when blood pressure drops in 2 cases,lower limb mild irritation pain in 1 case.There was no intraoperative complications such as pulmonary embolism,fractured ribs during operation.The effective pain relief rate of 3th day and 3,6 months was 69％,74％,78％.No original vertebral body collapsed again.And postoperatively,there was 2 cases of neurologic symptoms.After 6 months,the ADL scores were improved significantly (P ＜ 0.01).Conclusions Percutaneous vertebral plasty in the treatment of spinal tumor and metastatic tumor,has a good pain relieving effect,and it' s a kind of practical new technology,which is worthy of popularization and application.
