PVP在伴有顽固性腰背痛的椎体血管瘤患者治疗中的应用

Clinical application of percutaneous vertebroplasty for vertebral hemangiom accompanied with refractory low back pain

目的探讨经皮椎体成形术(PVP)治疗伴有顽固性腰背痛的椎体血管瘤的临床疗效,总结临床经验。方法回顾分析2009年8月～2011年7月共计21例伴有顽固性腰背痛的症状性椎体血管瘤患者,平均年龄46岁,经PVP治疗,所有患者均经影像学确诊,并排除手术禁忌症。结果 21例患者病变椎体均成功完成手术,术后平均随访12个月,术后6月治疗有效率95%,术后12月治疗有效率84%。术后X线片、CT显示骨水泥填充病灶良好,分布均匀,未出现骨水泥过敏反应及栓塞等并发症。结论 PVP能显著缓解椎体血管瘤引起的顽固性腰背部疼痛,是一种安全、有效的微创治疗方法。

Objective To investigate the clinical efficiency of percutaneous vertebroplasty（PVP）for patients with refractory low back pain caused by vertebral hemangioma,and to summarize the clinical experience.Methods 21 vertebral hemangioma patients with refractory low back pain who were treated from August 2009 until July 2011 underwent PVR.Their average age was 46.All patients were confirmed through radiological examinations.All contraindications were ruled out.Results PVP were successfully performed on the affected intevertebral bodies in these 21 patients.All patients were followed up for 12 months.The treatment effective rate was 95% in six months after surgery,and the rate was 84% in twelve months.Postoperative X-ray and CT scan indicated that the bone cement filling was uniformly distributed body.There was no neurological impairment,bone cement allergy or embolism in these patients.Conclusions Percutaneous vertebroplasty can significantly relieve intractable low back pain caused by vertebral hemangioma.It is a safe and effective minimal invasive procedure.
