Purpose : The use of low dose chest CT for lung cancer screening has led to increasing the incidental finding of small and subsolid pulmonary nodules. Various localization techniques for pulmonary nodules have been developed, because it is difficult to find deep seated or subsolid pulmonary nodules in minimally invasive thoracic surgery (MITS). In this study, we aimed to evaluate safety and accuracy of preoperative dual localization with microcoil and indocyanine green (ICG).

Methods : We retrospectively analyzed 36 patients (36 nodules) who underwent wedge resection and preoperative dual localization with microcoil and ICG between April 2019 and August 2021. After localization, wedge resection with minimally invasive approach was followed in all patients using fluorescent imaging and C-arm fluoroscopy.

Results : Total 36 nodules were resected from 36 patients. The mean depth from visceral pleura was 16.15 ± 14.21 mm, and the mean operation duration was 88 ± 49.08 min. The mean localization procedure time was 12.2 ± 4.14 min, and the mean surgical margin distance was 12.1 ± 11.33 mm. There were no significant complications and conversion to thoracotomy. Three cases had leakage of ICG, and other 5 cases had microcoil misplacement, but dual localization was successfully performed in all patients. Conversion to lobectomy was required in one patient because invasive adenocarcinoma was diagnosed by frozen section.

Conclusion : Preoperative dual localization with microcoil and ICG is feasible and enable successful MITS pulmonary resection of deep small pulmonary nodules.
