经皮椎体成型术对脊椎转移癌患者止痛效果的评价

目的:评价经皮椎体成型术对脊柱转移癌患者减轻背痛症状的疗效.方法:从2005年1月至2009年4月51例患者共101个椎体进行了经皮椎体成型术,术前及随访终点使用PI-NRS疼痛评估系统(0分为无疼痛,10分为最严重的疼痛)对患者进行疼痛评分.同时记录患者镇痛药的使用情况.疼痛评分减低至少2分认为临床有效.结果:全部患者术后均无严重并发症发生.随访1-9个月(平均3.6个月),51例患者中48例(94%)治疗后疼痛明显减轻,38例患者(75%)停用镇痛药治疗.结论:经皮椎体成型术对脊柱转移癌患者减轻背痛症状安全有效.

EVALUATION OF THE ANALGESIC EFFECT OF PERCUTANEOUS VERTEBROPLASTY FOR PATIENTS WITH VERTEBRAL METASTASES

Objective:To assess the effects of percutaneous vertebroplasty (PVP) for relieving back pain in patients with vertebral metastases.Methods; From January 2005 to April 2009,51 patients underwent PVP on 101 vertebrae. Pain was evaluated with the pain intensity numeric rating scale (PI-NRS) (0 = no pain; 10 = the worst pain) before the procedure and at the end of follow-up.Analgesic drugs were recorded meanwhile.A reduction of at least two points of the PI-NRS score was considered clinically significant. Results; No severe complications were observed after operations. During follow-up for 1-9 months (mean 3.6 months) ,a clinically significant pain reduction was observed in 48 of 51 patients (94%),and 38 of 51 patients (75%)did not need analgesic drugs.Conclusion; Vertebral metastases-induced back pain can be safely and effectively controlled by PVP.
