CT、"C"臂引导下经皮椎间盘内电热治疗疗效分析

目的探讨经皮椎间盘内电热治疗(IDET)对椎间盘源性腰腿痛的临床疗效。方法对40例41个椎间盘行CT和“C”臂X光透视引导下IDET治疗的临床疗效予以回顾性分析。采用WHO疼痛缓解标准，将疼痛缓解程度分为完全缓解(CR)，部分缓解(PR)，轻微缓解(MR)和无缓解(NR)。结果39个椎间盘穿刺成功并做IDET治疗。椎间盘电热治疗后即刻有轻微缓解31例(31／38)．无缓解7例(7／38)。术后随访在1～7d内的有效率为55％，7d～1个月内的有效率为34％，术后1～3个月随访有效率为76％，术后3～6月随访总体有效率达87％。2例15～S1椎间盘突出因穿刺失败而未行治疗。结论IDET适于治疗椎间盘退行性变破裂引起的慢性腰腿痛。疗效和疼痛缓解随着术后时间的延长而逐渐明显。

Preliminary results of intradiscal electrothermal treatment guided by CT and C-arm X-ray Unit

Objective To discuss the effect of IDET treatment for low back pain. Methods Retrospectively analysed the treatment results of 40 cases 41 sections of interdiscal protrusion under CT and C arm X-ray guidance. Two cases of L5-S1 intradiscal protrusion were failed and 38 cases were successful with IDET. Results We adopted WHO criteria of pain relief and palliative care. Fifty-five percent cases were CR or PR between 1 day and 1 week postoperatively, and 34% cases had CR or PR between 1 week and 1 month postoperatively, also 76% cases between 1 and 3 months postoperatively, and 87% cases within 3 to 6 months postoperatively. Conclusions IDET is suitable for chronic low back pain caused by intrediscal rupture. Postoperative healing includes 4 stages: 1 to 7 days is the release stage, 7 days to 1 month is the discal edema stage, 1 to 3 months is the discal rehabilitation stage and 3 to 6 months is the discal stable stage.
