MSCT在经皮椎体成形术的临床应用与疗效评价

目的:探讨骨质疏松压缩骨折经皮椎体成形术(PVP)伤椎高度的变化的MSCT与临床疗效的评价。方法:经MSCT检查确认25例病变椎体,术前在CT图像上模拟穿刺路径及选择PVP穿刺方式,术后一周内及术后半年进行伤椎复查,对影像数据与临床资料进行统计学分析,从MSCT及临床角度对疗效进行评价。结果:本组患者单侧椎弓穿刺成功率92%,术后腰背部疼痛明显减轻,术前、术后视觉评分、Cobb’s角以及伤椎压缩率比较统计学有显著性差异,而术后及半年后的视觉评分、Cobb’s角以及伤椎压缩率无显著性统计学差异。结论:MSCT能为PVP提供准确的解剖学数据,改善PVP效果,并能在术后随访提供重要的临床信息。

Clinical Evaluation of MSCT in Percutaneous Vertebral Plasty

Objective: To investigate the osteoporosis compression fracture percutaneous vertebral plasty (PVP) injured vertebral height change of multi-slice CT (MSCT) and clinical evaluations. Methods: 25 cases of osteoporosis vertebra compression fractures was by MSCT examination confirmed, preoperative simulation puncture path on CT image and select PVP puncture method, statistical analysis was carried out on the image data and clinical data, from the MSCT and clinical curative effect evaluation. Results: This group of patients with unilateral vertebral arch puncture success rate 92%, significantly reduce the lumbar pain after surgery. There is significant statistical difference in pre and post PVP vertebral compression ratio, Cobb's Angle and visual analogue scale, there were no significant difference in vertebral compression ratio, Cobb's Angle and visual analogue scale after six months follow-up data's. Conclusions: MSCT can provide accurate anatomic data for PVP in the selection of puncture needle and puncture path, can help improve PVP clinical effect, and can provide important clinical information in postoperative follow-up.
