CT定位下经皮穿刺射频消融治疗肺肿瘤疗效分析

目的探讨CT引导下集束电极射频治疗肺恶性肿瘤的疗效。方法对2004年以来在CT定位引导下，采用RFA-1多极射频肿瘤消融系统，用多极经皮穿刺到肺内肿瘤进行射频消融治疗，每针次温度70℃～90℃左右维持10min或15min。结果44例患者经CT引导行射频消融51例次，绝大多数病灶复查CT均有不同程度缩小或CT值下降30～37，疼痛等症状明显缓解。无严重并发症，无围手术期死亡。结论CT定位下经皮多极射频消融对肺恶性肿瘤的近期疗效明显，对晚期肺癌、多发性肺转移瘤及不能耐受手术者，可作为综合治疗的方法之一。

The feasibility and efficacy of percutaneous radio - frequency ablation in the treatment of pulmonary neoplasm

Objective To explore the feasibility and efficacy of percutaneous radio - frequency ablation through the guidance of CT in the treatment of pulmonary neoplasm. Methods Using CT to locate the tumor and determine the optimal approach, RFA - 1 ablation needle was inserted into the target lesion. Radiofrequeney was applied via the electrode for 10 or 15 min at 70 ℃-90 ℃. Results Total 44 cases were received 51 times of radio - frequency ablations through the guidance of CT. Reduced size of the pulmonary neoplasm and reduced chest CT number by 30 - 37 were founded in most cases. After the therapy, chest pain was alleviated in most cases. There was no severe complication and no case death. Conclusion Percutaneous radio - frequency ablation through the guidance of CT is one of feasible and effective treatment in uuoperateble or late stage solid lung cancer.
