Abstract

背景与目的近年来由于肺癌筛查工作的广泛开展,越来越多的肺部小病灶被发现,本研究旨在分析计算机断层扫描(computed tomography, CT)引导下经皮肺小病灶(直径 < 2 cm)穿刺活检结果及并发症、预后。方法选择2015年1月-2017年12月期间行CT引导下经皮肺穿刺活检术41例肺内周围型病灶,单发病灶39例多发病灶2例,病灶最大径5-20(13.1±5.2)mm。病灶距离肺表面深度1-45(16.5±13.7)mm,毛玻璃样成分(ground glass opacity, GGO)比例0%-100%(66.8%±35.2%)。结果41例患者进行43次穿刺。43次穿刺均成功取得病理组织。手术证实其中非典型腺瘤样增生(atypical adenomatous hyperplasia, AAH)3例,鳞癌1例,腺癌37例(原位癌7例,微侵润癌5例,侵润性25例,有2例患者为双原发癌),炎性病变2例。除2例炎性病变正在随访中,活检与手术病理吻合度(特异性)为100%。气胸22例,发生率51.2%,需闭式引流2例,17例发生咯血,发生率39.5%,均为自限性。2例出现颅内空气栓塞经治疗痊愈,发生率4.6%。结论对于肺部小病灶CT引导经皮穿刺技术上可行。但对于肺部小病灶尤其是纯GGO的穿刺活检,目前还需要持谨慎态度。
