PVP及PKP治疗中责任椎的选择

Selection of responsible vertebrae in the treatment of PVP and PKP

目的探讨PVP(经皮椎体成形术)及PKP(经皮椎体后凸成形术)治疗中责任椎的选择对预后疗效的影响。方法回顾性研究2007年1月1日至2011年6月1日在我院行PVP或PKP病人276例,其中单椎体者204例病人,双椎体者66例病人,三椎体者6例病人,通过术前认真查体及阅X线片、CT、MRI,选择正确的责任椎,给予PVP或PKP。结果 276例患者术后第2天下地活动,术后1个月恢复伤前生活,无节段血管、脊髓等穿刺损伤,无肺栓塞、血管栓塞等并发症发生。结论正确选择责任椎,能有效避免手术失败,PVP及PKP能迅速缓解疼痛,恢复部分椎体高度,改善患者生活质量,提高疗效。

Objective To explore the effect of the selection of responsible vertebrae in percutaneous vertebroplasty （PVP） and percutaneous vertebral kyphosis angioplasty （PKP） on the prognosis. Methods Clinical data of 276 patients, who underwent PVP or PKP from January 1, 2007 to June 1, 2011 in our hospital, were retrospectively analyzed. Among them, 204 patients had operation on single vertebra, 66 patients had operation on double vertebrae, and 6 patients had operation on triple vertebrae. Physical examination and imaging reading, including X-ray, CT, and MRI were performed seriously preoperative to select right responsible vertebrae, and the decision was made to perform PVP or PKP. Results All the 276 patients could exercise off bed at the 2nd day after the operation. They could recover to the situation before injury only 1 month after the operation. No complications such as segmental vessels or spinal cord puncture injury, pulmonary embolism, or vascular embolism occurred. Conclusion The right selection of responsible vertebrae can effectively avoid the failure of the operation. PVP and PKP can rapidly relieve pain, restore partial vertebral height, improve the quality of life, and improve efficacy.
