肺部小结节胸腔镜术前CT引导下硬化剂定位的临床应用价值

Clinic research of video-assisted thoracoscopic solitary pulmonary nodule resection after CT-guided hardening agent localization

目的探讨肺部小结节胸腔镜术前cT引导下注射硬化剂定位的临床应用价值。方法2010年12月至2012年1月，27例患者，检出29枚孤立性肺结节，胸腔镜术前在CT引导下注射硬化剂（医用胶）定位后成功行胸胸腔镜下肺楔形切除术。结果cT引导下注射医用胶定位成功率100％。定位时间（6．87±6．75）min，定位后无严重并发症，29枚小结节均成功定位后行胸腔镜下肺楔形切除术，无中转开胸手术，手术后均经病理确诊。结论cT引导下注射硬化剂（医用胶）定位方法安全、可行，效果可靠。

Objective The aim of this study is to evaluate the efficacy and safety of preoperative CT-guided hardening a- gent localization. Methods From December 2010 to January 2012, 27 patients with 29 solitary pulmonary nodules who had undergone CT-gnided hardening agent localization and video-assisted thoracoscopic surgery （VATS） were studied. Results All cases were underwent CT-guided hardening agent localization successfully, and no patient had serious complication that required any intervention. The diameter of nodules ranged from 3 to 21 rnm as measured by CT [mean （11.27 ±6. 32） mini. The distance between the center of nodule and visceral pleural ranged from 4 to 38 mm [ mean （ 14.45 ± 4.32） mini. Conversion from VATS to thoracotomies was not necessary during the diagnostic resection procedure nodules. 29 solitary pulmonary nodules underwent thoracoscopic wedge resection, and no intra- or postoperative mortality or morbidity was recorded. Conclu- sion CT-gnided hardening agent localization before video-assisted thoracoscopic solitary pulmonary nodule resection is a safe and effective procedure for accurate diagnosis and resection of indeterminate solitary pulmonary nodules.
