Objective To investigate the accuracy and safety of preoperative CT⁃guided coil localization of subcentimeter soli⁃tary small pulmonary nodule( SPN) and followed by video⁃assisted thoracic surgery( VATS) resection under radioscopy. Methods From March 2014 to April 2015, 53 patients with subcentimeter SPN underwent CT⁃guided coil localization of SPN and VATS resection under radioscopy were retrospectively reviewed. Results The SPNs were localized and resected with success rate of 100%. The complications associated with procedure included 4 pneumothorax, 2 local parenchymal hemorrhage and 1 hemopneumothorax. Twenty⁃one nodules were confirmed as malignancies, including 16 well differentiated adenocarcinoma, 3 minimally invasiveadenocarcinoma and 2 metastatic lesions. Thirty⁃two nodules were confirmed as benign lesions, including 12 chronic granulomatous inflammation, 10 inflammatory fibro⁃sis, 5 atypical adenomatous hyperplasia, 3 sclerosing hemangioma, and 2 harmatoma. Two patients suffered from pulmonary infection, and recovered by conservative treatment. The postoperative hospital stay was 3⁃7 d,with average length of stay (4�11±1�03)d. Conclu⁃sion CT⁃guided coil localization followed by VATS resection under radioscopy can be an effective and safe procedure for accurate re⁃section and diagnosis of subcentimeter pulmonary nodules.%目的探讨CT引导下对直径小于10 mm孤立性肺部小结节（ SPN）弹簧圈定位及同期X线透视下电视胸腔镜手术（ VATS）切除的准确性及安全性。方法回顾性分析2014年3月至2015年4月收治的53例亚厘米SPN患者，采用CT引导下弹簧圈定位及在X线透视下进行VATS精准切除。结果53例患者亚厘米SPN经CT定位后均经VATS准确切除，切除成功率为100％。 CT引导下定位后出现气胸4例，局部肺组织出血2例，气胸合并出血1例。 SPN切除后病理显示，恶性病变21例，其中原位高分化腺癌16例、微侵袭腺癌3例、转移癌2例；良性病变32例，其中慢性炎性肉芽肿12例、局灶性炎纤维化10例、不典型腺瘤样增生5例、硬化性血管瘤3例、肺错构瘤2例。术后肺部感染2例，经保守治疗治愈。术后住院时间3～7 d，平均住院时间为（4�11±1�03）d。结论 CT引导下弹簧圈定位和同期VATS切除是诊治亚厘米SPN较为准确和便捷的方法。
