Abstract

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﹤8 cm,其中32个病灶直径﹤5 cm.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。
