多层螺旋CT引导下椎体成形术治疗脊椎转移瘤的体会

Treatment of vertebral metastases using multislice CT- guided percutaneous vertebroplasty

目的探讨多层螺旋CT引导下经皮穿刺椎体成形术(PVP)治疗脊椎转移瘤的方法和效果。方法回顾性分析25例脊柱转移瘤患者,在CT引导下行经皮穿刺椎体成形术的治疗效果和并发症。结果25例30个椎体CT下穿刺准确率100%。术后患者均有不同程度的疼痛缓解。1个月时疼痛完全缓解(CR)18例,部分缓解(PR)7例。治疗中出现1例骨水泥(PMMA)外溢至椎间盘。但未出现临床症状。结论多层螺旋CT引导下椎体成形术操作简便、准确、安全,对提高患者的生存质量有很好的应用价值。

Objective To evaluate the multislice CT - guided percutaneous vertebroplasty （PVP） in treatment of vertebral metastases. Methods The efficacy and complications of CT- guided PVP in 25 patients with vertebral metastases were retrospectively reviewed. Results The percutaneous paracentesis was successful in all 30 vertebrae in 25 patients. After PVP, the pain in all patients subsided gradually. Complete remission was obtained in 18 cases out of 25, and partial remission was accomplished in the rest 7 cases in one month after the intervention. In one case, bone cement （polymethy methacrylate PMMA） leaked into vertebral disc during the procedure while the treatment remained asymptomatic eventually. Conclusion The multislice CT - guided PVP is a simple, precise, and safe interventional procedure, which is a practical treatment to improve the life quality of patients with vertebral metastases.
