CT导向下周围型肺癌射频消融治疗的临床分析

目的 探讨CT导向下射频消融（RFA）治疗周围型肺癌的价值。方法 43例周围型肺癌进行了CT导向下射频消融治疗。术前常规CT导向下经皮穿刺活检获取病理学诊断，鳞癌15例，腺癌19例，腺鳞癌4例，大细胞癌3例，未分化癌2例。全部瘤体直径均〈8cm，其中32个病灶直径〈5cm。结果 全部病例手术顺利，术中并发少量气胸者3例，液气胸1例，大量气胸行闭式引流者1例。术后分别在3和6个月CT复查，显示43个病灶中40个体积均有不同程度的进行性缩小，肿瘤内部均出现大片不规则低密度区；3例患者病灶体积无变化，边缘有环状强化，提示肿瘤复发。结论 CT导向下经皮穿刺RFA治疗周围型肺癌是安全有效的微创技术，值得推广应用。

CT guided percutaneous radiofrequency thermal ablation of peripheral lung carcinoma

Objective To assess the therapeutic value of CT guided percutaneous radiofrequency thermal ablation(RFA)for peripheral lung carcinoma(PLC).Methods Forty-three patients with PLC were treated with RFA under the CT guidance.The patients included 26 males and 17 females,and the age ranged from 52 to 76 years.The CT guided percutaneous biopsies were performed to obtain the pathology before the procedures.Results The operations in all cases were successful,little amount of pneumothorax was found in 3 cases,liquid-pneumothorax in 1 case,and large amount of pneumothorax was drainaged in 1 case.The volume of the lesion in 40 cases from 43 patients was diminished gradually at 3 and 6 months follow-up after the procedures.No change in the volume of lesion with peripheral enhancement was seen in 3 cases.Conclusion CT guided percutaneous RFA for PLC is a safe,effective,and minimal invasive procedure.
