经皮椎体成形术缓解脊柱疼痛的效果分析

Clinical application of percutaneous vertebroplasty for spinal pain relief

目的观察经皮椎体成形术(PVP)缓解脊柱疼痛的治疗效果。方法应用PVP治疗81例103个椎体,其中42例骨质疏松症57个椎体,39例椎体良恶性肿瘤46个椎体。治疗前和治疗后3天应用视觉模拟评分法(VAS)评定疼痛的程度,并在6个月内观察疗效。结果所有病例的PVP治疗都成功完成。术后3天患者VAS平均值(2.81±1.25mm)低于术前平均值(8.15±1.31mm)(P<0.01)。疼痛缓解有效率为86.4%。止痛效果维持至少6个月。15例发生骨水泥椎体外渗漏。结论PVP能够明显缓解骨质疏松症和椎体良恶性肿瘤所引起的疼痛。

Objective To study the pain-relieved efficacy of percutaneous vertebroplasty （PVP） in the treatment of diseases in spine vertebrae. Methods Eighty-one patients with 103 vertebrae underwent PVP, including 57 osteoporosis in 42 cases and 46 vertebral tumors in 39 cases. Intraosseous venography was performed followed by injecting bone cement under the fluoroscopy. The score of visual analogue scale point （VAS） （ 10-point scale） before vertebroplasty, 72 hours after vertebroplasty was recorded respectively. Result of pain relief and complications were observed. Results The procedure was technically successful in all patients. Bone cement leakage into adjacent paravertebral soft tissue occurred in 15 cases. The score of VAS was（2.81±1.25mm） marks at 72 hours after PVP significantly lower than the average score of VAS before treatment（8.15±1.31mm）（p〈0.01 ）.The analgestic effectiveness was 86.4%. The analgestic time lasted 6 months. Conclusion PVP can provide significant pain reduction in the treatment of patient with osteoporsis and vertebral tumors disease.
