CT引导下细针多方向经皮肺穿刺活检的临床应用

目的：评价CT引导下经皮肺穿刺活检对周围性肿块的诊断价值，探讨并发症发生的原因。方法：CT引导下经皮肺穿刺活检的肺部占位性病变60例，均采用切割针和自动枪取材，分析诊断正确率、并发症发生率及影响因素。结果：本组60例全部取得有效标本，穿刺成功率为100％。58例获得准确诊断，包括原发性肺癌49例、结核3例、炎性假瘤2例、转移瘤2例、结节病1例、肺曲菌病1例，诊断正确率为96．6％。并发气胸8例，出血10例。气胸及出血的发生与穿刺针通过含气肺组织的长度均有明显关系（P〈0．01），气胸的发生与患者肺气肿的存在无明显关系（P〉0．05），位于肺野内带的病灶较外带病灶更易发生出血（P〈0．01）。结论：CT引导下经皮肺穿刺活检操作简便、安全，诊断准确性高。术前准确定位，分步进针，熟练的技术操作可以减少并发症的发生。
