    Journal: J Thorac Imaging; 2020 Jul; 35(4):260-264. PubMed ID: 32032250.
    Abstract:
    OBJECTIVE: We sought to introduce a localization procedure (methylene blue-stained N-butyl cyanoacrylate and N-octyl cyanoacrylate glue) in localizing pulmonary small nodules and ground-glass opacities before thoracoscopic resection, and to evaluate its efficacy. METHODS: A total of 20 patients with pulmonary small nodules and/or ground-glass opacities, who underwent video-assisted thoracoscopic surgery from August 1, 2017 to March 1 2018, were included in the study. RESULTS: A total of 24 lesions in 20 patients underwent blue-stained glue localization. The success rate of localization was 100%, with a mean dose of 0.04±0.01 mL blue dye and 1 mL glue used for each lesion. The average time for the whole localization procedure was 15.4±6.3 minutes. All lesions were intraoperatively localized by visual inspection in combination with palpation. The complications related to the localization procedure included mild pneumothorax occurring in 9 patients and minor pulmonary hematoma in 4 patients. No pain or distress was reported. CONCLUSIONS: Blue-stained glue injection is technically feasible and safe to localize pulmonary small nodules and ground-glass opacities before thoracoscopic resection.
