CT Guided Indocyanine Green Injection for Localization of Small Pulmonary Nodules in Thoracic Surgery
Objective To explore the feasibility and safety of CT guided indocyanine green(ICG)injection for localization of small pulmonary nodules in thoracoscopy surgery.Methods Thoracoscopic resection of pulmonary nodules was performed in 96 cases with a total of 124 pulmonary nodules from September 2021 to June 2023.Within 1 day before surgery,under the CT guidance,we firstly confirmed that the needle tip was less than 10 mm from the nodule,and then 0.04 ml of ICG solution was injected for pulmonary nodule localization,followed by thoracoscopic resection of pulmonary nodules.Results A total of 124 nodules were successfully located in the 96 patients.The average nodule size was 8 mm(range,5-10 mm),and the average positioning time was 11 min(range,9-20 min).The duration of fluorescence development lasted for over 22 h.Postoperative pathology showed 45 lesions of adenocarcinomas in situ,17 lesions of atypical hyperplasia,and 62 lesions of adenocarcinomas(including 53 microinvasive adenocarcinomas and 9 invasive adenocarcinomas).Among them,8 patients had mild pneumothorax and 3 patients had blood in sputum,all of which did not require special treatment.Conclusion CT guided ICG injection has high accuracy,safety,and effectiveness for localization of small pulmonary nodules.
