摘　　要：随着电子计算机断层扫描(CT)技术在临床的逐渐广泛应用,肺部小结节诊断率明显上升。即使应用正电子发射计算机断层显像(PET-CT)或者经皮穿刺活检等技术,准确诊断肺部结节仍面临挑战。微创胸腔镜手术在肺部小结节的病理诊断和根治切除方面发挥至关重要的作用。但是由于胸腔镜本身的局限性,术中准确找到并切除肺内小结节是手术的难点,也成为限制胸腔镜手术开展的因素之一。目前,胸外科领域已有多种胸腔镜术前肺部结节定位技术,本文则对临床上最常用的三种CT引导下经皮穿刺肺部小结节定位技术:经皮hookwire穿刺定位法、经皮穿刺碘油染色法以及经皮穿刺弹簧圈植入法进行详细介绍。At the use of computed tomography( CT) becomes widespread in clinical,it greatly increases the likelihood of detection of small nodules. The accurate early diagnosis of these small nodules is challenging,even with positron emission tomographycomputed tomography( PET-CT),or image-guided percutaneous biopsy. Video-assisted thoracoscopic surgery( VATS) is a minimally invasive surgery for management of lung nodules,both for curative resection and diagnostic. One of the major problems often encountered during VATS is localization of target nodule. Several preoperative and intraoperative techniques have been described for nodule localization when performing VATS.Here we summerize 3 primary procedures about percutaneous localization under CT guidance:hook-wire localization,Lipiodol localization,microcoil localization.
