目的:用CT评价肺部恶性肿瘤多弹头射频治疗的近期疗效。方法:CT引导下经皮肺穿刺插入多弹头射频电极行射频热凝固治疗40例共58个病灶,治疗后即时及3或6个月后CT扫描评价治疗效果。结果:治疗后即时CT扫描显示病灶周边渗出,38个病灶密度减低,31个病灶内出现小气泡影;3或6个月后CT复查3个病灶完全消失,36个缩小,10个增大,9个基本无改变。37例有肺部相关症状及体征在治疗后消失或好转。结论:多弹头射频治疗肺部恶性肿瘤近期疗效确切,CT可准确引导射频针的插入及显示肺癌治疗后的病理改变。
Objective: To evaluate the short-term curative effect of multi-head radiofrequency ablation of lung malignant tumor with CT. Methods: Forty-eight lesions (58 lesions) were treated by CT-guided percutaneous pulmonary puncture and multi-warhead radiofrequency electrode coagulation. The therapeutic effect was assessed immediately after CT scan with 3 or 6 months after treatment. Results: Immediate CT scan showed exudation around the lesion, the density of 38 lesions was reduced, and small bubbles appeared in 31 lesions. After 3 or 6 months, 3 lesions disappeared completely, 36 reduced and 10 increased, 9 basic no change. 37 cases of lung-related symptoms and signs disappeared or improved after treatment. Conclusion: The multi-warhead radiofrequency treatment of lung cancer is effective in the near future. CT can accurately guide the insertion of radio-frequency needle and show the pathological changes after lung cancer treatment.
