Abstract：Objective:To evaluate the CT-guided positioning of methylene blue staining wedga-shape excision of lung of solitary pulmonary nodules clinical application.Methods:From January 2015 to January 2016 in hospital 25 patients treated by thoracic surgery,the first under CT guidance of 28 small nodules positioned methylene blue,underwent lobectomy,positioning time statistics,the success rate,complications,success rate and so on.Results:The group of 25 patients with solitary pulmonary nodule diameter of (10.26±5.58) mm,from the parietal pleura (11.06±8.22) mm.28 solitary pulmonary nodules in CT-guided positioning of methylene blue,1 case of failure,the success rate of 96%,positioning time of (22.60±4.86) min,operative time was (18.02±4.45).A small amount of pneumothorax four 4 cases (16%) occurred in all patients after locating a small amount of hemoptysis in 1 case (4%),pleural reaction in 2 cases (8%),There is no blood chest,blood pneumothorax,pulmonary vascular thrombosis,the symptomatic treatment are improveddoes not appear no hemothorax,pneumothorax,pulmonary vascular air embolism,etc,symptomatic handling were improved.28 small nodules pathology results suggest that 12 cases (42.9%) patients with pathologically confirmed malignant fast,16 benign lesions.Conclusion:The use of methylene blue in the CT-guided pulmonary nodules for staining and positioning for the thoracic lobe wedge resection (VATS) to provide accurate positioning,with simple operation,accurate positioning,cheap,easy access to materials and other advantages,can be shortened accordingly time to increase wedga-shape excision of lung success rate.
