多靶点射频热凝修复术治疗椎间盘突出症400例

Clinical application of multi-target radiofrequency thermocoagulation for prolapse of intervertebral disc:a report of 400 cases

目的探讨多靶点射频热凝修复术一次性治疗椎间盘突出症的临床实用性和术中热凝靶点定位,以提高疗效及减少并发症。方法400例椎间盘突出症患者接受了多靶点射频热凝治疗。根据临床表现及MRI或/和CT片确定射频热凝的靶点位置和热凝周期,同时设计术中患者体位和穿刺途径。结果400例中优364例(91.0%),良20例(5.0%),可8例(2.0%),差8例(2.0%),优良率96.0%,有效率98.0%。未出现并发症及死亡病例。结论多靶点射频热凝修复术是治疗椎间盘突出症一种安全、微创、优良率高的治疗方法。

Objective To explore the clinical practice and the target location of radiofrequency thermocoagulation for prolapse of intervertebral disc. Methods A tolal of 400 patients with prolapse of intervertehral disc underwent radiofrequency thermocoagulation. The location of target in operation and cure cycle time were defined according to the clinical symptom and MRI or CT,and the posture of patients and pathway of puncture were decided. The annular fibrosus prosthesis was taken to biger prolapsed intervertebral disc （ transverse diameter 〉 7 mm, sagittal diameter 〉 5 mm） after thermocoagulation. Results Out of 400 patients,364 （91.0%）were excellent effect,20（5. 0% ）were good,8 cases（2. 0% ）were medium,and 8 cases（2.0% ） were poor. The rate of goodness was 96. 0%, and the effective rate was 98.0%. There were no complications and death cases during operation. Conclusions Multi-target radiofrequency thermocoagulation repairing intervertebral disc and annular fibrosus is a safe ,minimally invasive and effective therapeutic method for treating prolapse of intervertebral disc.
