7、TS)切除肺内小结节的安全性和有效性。方法对47例肺内小结节患者(共53个结节,直径<30mm)行术前CT引导下微弹簧圈定位,将微弹簧圈植入紧邻肺小结节边缘的肺组织内,使22个结节内的微弹簧圈的尾部位于脏层胸膜之外。于定位当日或次日行VATS切除肺内小结节,术后标本送病理学检查。结果VATS下完整切除全部肺内小结节(直径3~26mm)。51个(51/53,96.23%)肺内小结节应用微弹簧圈定位成功,2个(2/53,3.77%)微弹簧圈植入后发生移位;定位术中并发症包括无症状性气胸6例、轻微肺泡出血9例。结论术前CT引导下
8、经皮穿刺微弹簧圈定位肺内小结节安全、有效,有助于提高VATS切除的准确率。[关键词]肺内小结节;术前定位;微弹簧圈[中图分类号]R815;R445[文献标识码]A[文章编号]1672-8475(2014)03-0145-04[1][2]肺癌占我国肿瘤患者死因的第一位。研究表存率达60%~90%,而Ⅲb和
