经皮椎体穿刺活检是目前常用的活检方法,但受到脊柱解剖、活检组织量等因素的影响,限制了穿刺活检的应用[1]。近几年来,经皮椎体成形术在治疗椎体转移瘤方面取得了显著效果[2、3]。2007年4月～12月我们在应用经皮球囊后凸椎体成形术治疗17例脊柱转移瘤患者时术中取活检,以进一步明确诊断,为后续治疗提供依据。 Percutaneous vertebroplasty biopsy is currently the biopsy method, but by the spine anatomy, biopsy and other factors, limiting the application of biopsy [1]. In recent years, percutaneous vertebroplasty has achieved remarkable results in the treatment of vertebral metastases [2,3]. April 2007 ~ December, we applied percutaneous balloon kyphoplasty in 17 patients with spinal metastases surgery biopsy to further confirm the diagnosis, provide the basis for follow-up treatment.
