摘要
目的观察射频消融术(RFA)治疗腰椎间盘突出症的疗效及安全性。方法对30例确诊的腰椎间盘突出症患者,根据临床症状、CT或MRI结果制定立体定位穿刺方案及靶点位置,在大C型臂X线引导下穿刺并置于突出物中,感觉神经、运动神经及温度测试后,92℃热凝消融,并持续100s,重复4个周期,依次消融整个突出物。结果30例患者治疗6个月后,VAS评分(静息痛+运动痛)从7.83±0.33降至2.37±0.48(P<0.05)。据改良Macnab疗效评定标准,9例治疗效果为优,12例良,5例可,4例差,有效率86.7%。无一例出现严重并发症。结论RFA是治疗腰椎间盘突出症的有效、安全的微创方法之一。
Objective To observe the clinical effects and safety of radiofrequency thermocoagulation in treating the lumbar intervertebral disc protrusion. Methods Thirty patients with lumbar intervertebral disc protrusion, whose diagnoses were confirmed by clinical manifestations and CT findings, were involved in this study. The needle was punctured to the target point of the diseased intervertebral space under C-arm fluoroscopic guidance. After the testing of sensory nerve, motor nerve and temperature was made, the target needles were heated until the nerve radiofrequency temperature meter reached the point of 92℃. This point of temperature was held for 100 seconds and the procedure was repeated for four cycles. Results Six months after the treatment, all patients showed an obvious improvement in VAS, which decreased from 7.83 ± 0.33 before operation to 2.37 ± 0.48 after treatment （P〈0.05）. According to the modified Macnab therapeutic evaluation criteria, excellent result was seen in 9, good result in 12, fair result in 5 and poor result in 4 cases, with a total effective rate of 86.7%. No serious complications occurred in all patients. Conclusion Radiofrequency thermocoagulation is an effective and safe method for the treatment of lumbar intervertebral disc protrusion.
