摘要目的 利用红外热像图评估腰椎间盘射频靶点热凝术的临床疗效.方法 抽取2017年11月至2018年11月于郑州大学第一附属医院行腰椎间盘射频靶点热凝术的患者30例,收集其病历资料和MRI影像学结果.将射频靶点热凝术治疗前后测温区温差的变化(△TD)与疼痛强度的变化(ΔVAS)相关联,分析30例患者手术效果及手术前后TD(测温区温差)、视觉模拟量表(VAS)评分.结果 治疗后总有效率为93.4％(28/30),未见手术相关并发症.30例患者术后TD、VAS均较术前改善(P<0.05),但ΔTD与ΔVAS未见明显相关性(r=0.252,F=1.906,P=0.178),术前TD越大,术后VAS评分越高,即术后临床疗效越差(r=0.769,F=40.413,P=0.00).结论 △TD不能反应治疗后 ΔVAS,但术前的红外热像图有助于预测患者术后VAS评分的下降和临床症状的改善.

abstractsObjective To evaluate the clinical efficacy of radiofrequency target thermocoagulation of lumbar intervertebral discs using infrared thermography. Methods Thirty patients with lumbar intervertebral disc radiofrequency target thermocoagulation in the First Affiliated Hospital of Zhengzhou University from November 2017 to November 2018 were selected. The medical records and magnetic resonance imaging ( MRI ) results were collected. The changes of temperature difference (△TD ) and the difference in visual analogue scale ( VAS ) scores (ΔVAS ) before and after radiofrequency target thermocoagulation were combined in the study. and analyzed the surgical results of 30 patients and the TD ( temperature difference in temperature measurement area) and VAS scores were analyzed. Results The total effective rate after treatment was 93. 4％ ( 28/30 ) , and no surgical complications were observed. The postoperative TD was and VAS was were improved in 30 patients ( P<0. 05 ) , but there was no significant correlation between ΔTD and ΔVAS ( r=0. 252 , F=1. 906 , P=0. 178). The bigger preoperative TD, the bigger postoperative VAS, the worse the clinical efficacy was (r=0. 769, F=40. 413, P=0. 00). Conclusions △TD can not reflect the △VAS, but preoperative infrared thermographic imaging is helpful to predict the decrease of VAS score and the improvement of clinical symptoms after treatment.
