椎体成形术治疗症状性椎体血管瘤:影像学随访评价

Imaging follow-up evaluation of percutaneous vertebroplasty for symptomatic vertebral hemangioma

目的探讨经皮椎体成形术(PVP)治疗症状性椎体血管瘤及影像学随访评价的临床应用价值。方法回顾性分析接受PVP治疗的24例(共29节椎体)椎体血管瘤患者的资料,对其术前、术后1周及术后1年随访时的X线平片、CT及MR检查结果进行统计学分析。结果 24例患者PVP均成功,骨水泥充填良好,未出现严重并发症;术后1周所有病变椎体前、后缘高度比(A/B)为0.83±0.15,术后1年A/B为0.83±0.20(t=-1.984,P>0.05)。随访未见新发椎体压缩性骨折,血管瘤无复发。结论 PVP是一种比较安全且有效的微创治疗椎体血管瘤的方法;影像学检查可用以评价PVP治疗效果。

Objective To explore the clinical value of percutaneous vertebroplasty （PVP） and imaging following-up in pa- tients with symptomatic vertebral hemangioma. Methods The complete follow-up data of 24 patients （29 vertebras） with symptomatic vertebral hemangioma were retrospectively analyzed. All the patients received PVP treatment, then the results of X-ray, CT and MRI before and 1 week, 1 year after operation were analyzed statistically. Results PVP was successfully completed in all 24 patients without serious complications, and the lesion areas were filled well with bone cement. One week after operation, the average ratio （A/B） of the involved vertebra＇s leading edge （A） and posterior border height （B） was 0. 83：t：0.15, while 1 year after operation, A/B was 0. 83：J：0. 20 （t---- --1. 984, P：〉0.05）. During the following-up, no new spinal compression fracture nor vertebral hemangioma was observed. Conclusion PVP for the treatment of symptom- atic vertebral hemangiomas is relatively safe, effective and minimally invasive. Imaging examination can be used to assess the therapeutic effect.
