背景与目的胸腔镜术中对于直径<1 cm的肺小结节较难准确定位.数年前即有学者开始尝试使用各种方法进行术前的肺小结节定位.本文从适应症、结果、并发症三个方面回顾性分析了胸腔镜术前CT引导下Hook-wire定位的临床应用价值.方法 2010年1月-2010年4月,20例患者于胸腔镜术前接受了CT引导下肺小结节Hook-wire定位.小结节直径从0.5 cm-2 cm(平均9.8 cm±5.3 cm).评价指标包括定位成功率,定位相关并发症,中转开胸比率等.结果20例患者中18例定位成功,CT定位花费时间平均为14.5 min,全组无严重并发症发生.结论胸腔镜术前CT引导下肺小结节Hook-wire定位有一定的临床应用价值,可帮助术中精确定位肺小结节位置,并且并发症发生率较低.%Background and objective It's difficult to localize the accurate position for some pulmonary nodules in video-assisted thoracoscopic surgery (VATS) wedge resection.The aim of this study is to retrospectively analyze the clinical significance of CT-guided preoperative pulmonary nodule localization technique.Methods Between Jan 2010 and Apr 2011,20 patients of the First Affiliated Hospital of Medical School of Zhejiang University underwent preoperative pulmonary nodule localization technique before performing VATS wedge resection of the pulmonary nodule.Diameter of the lesion ranges from 0.5 cm to 2 cm (average 9.8 cm+5.3 cm).It was evaluated with the success rate in localization technique, rate of localization related complications, and rate of transferring thoracotomy.Results Eighteen patients underwent successful CT-guided Hookwire localization, with the average time of 14.5 minutes.There was no serious complications.Conclusion CT-guided preoperative pulmonary nodule localization is a promising technique for small solitary pulmonary nodules.It could play an important role in accurate localization of small pulmonary nodules, and it is a safe technique with less postoperative complications.
