3:46 PM Abstract No. 54 - Percutaneous vertebroplasty for metastatic lesions of the cervical spine

Abstract

Purpose To evaluation the effectiveness of the three approaches of percutaneous vertebroplasty for metastatic lytic lesions of the cervical spine. Materials and Methods 40 patients with osteolytic metastases in 65 cervical vertebras received the treatment of PVP. The clinical data were retrospectively analyzed. The WHO standards and Visual Analog Scale were assessed before and after operation, and the three approaches were analyzed and summarized according to the different positions of the cervical body. Results The three groups of puncture path are respectively anterolateral approach, lateral approach, and anterolateral approach through disc space. All the cervical bodies were successfully punctured and injected with bone cement. Follow-up at least 3 months, 13 cases of complete remission (CR), 21 cases of part remission (PR), 2 case of mild remission (MR), 0 is no remission (NR) after operation in data integrity of the 36 patients, while the rate of the clinical effective (CR+PR) reaching 94.44%. Preoperative and postoperative patients with 24h, after one week, 3 months after operation, the VAS differences were statistically significant (P Conclusion Percutaneous vertebroplasty via anterolateral approach is a safe, effective technique in treating the osteolytic metastasis tumor of lower cervical vertebra (C4-C7). While treating metastasis tumor involved in C1, C2 and C3, it’s safe and feasible to choose percutaneous vertebroplasty via lateral approach and anterolateral approach through disc space.
