Abstract:
Objective To evaluate the clinical application of CT-guided localization with combination of methylene blue and a Hookwire system for small pulmonary nodules (SPNs) before video-assisted thoracoscopic resection.Methods CTguided localization the SPNs before resection in 56 patients and 60 nodules,then underwent video-assisted thoracic surgery (VATS) resection.Among 56 patients,19 males and 37 females,aged from 35 to 81 years,mean age was (61.1 ±8.9)years.Results SPNs diameter (6.80 ±4.12) mm,distance from the parietal pleura (15.38 ±4.63) mm.CT-guided localization success rate was 100％,positioning time (10.76 ± 8.17) min,8.9％ (5/56) had micro pneumothorax aftet positioning,7.1％ (4/56) occurrence of needle tract bleeding,no conservative treatment.VATS resection rate was 100％.The pathology of 60 lesions were shown:Bronchiolo-alveolar carcinoma(BAC) were 33 lesions(55.0％),BAC and adenocarcinoma were 11 lesions(18.3％),Atypicaladenomatous hyperplasia (AAH) were 7 lesions (11.8％),Inflammation were 4 lesions (6.7％),Harmatoma were 3 lesions(5.0％),Tuberculoses were 2 lesions(3.3％).Conclusion CT-guided localization with combination of methylene blue and a Hookwire system before video-assisted thoracoscopic resection 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 clinical application.
