Segmentectomy of a Peripheral Pulmonary Nodule Following Bronchoscopic ICG-Coil Localization: A Case Series

Preoperative localization of small, non-subpleural pulmonary nodules is a challenge in minimally invasive segmentectomy. Bronchoscopic placement of indocyanine green (ICG)-soaked microcoils enables intraoperative detection via near-infrared fluorescence (NIR), improving the precision and safety of resection. We report three patients with CT-suspected solid pulmonary nodules who underwent bronchoscopic ICG-coil placement. The interval between localization and surgery ranged from 1 to 7 days. All patients underwent uni- or biportal video-assisted thoracoscopic segmentectomy. The ICG coil was clearly visible intraoperatively, and the resections were completed without complications. Histology revealed squamous cell carcinoma, typical carcinoid tumor, and a metastasis from sigmoid colon carcinoma. Postoperative recovery was uneventful in all patients. Bronchoscopic ICG-coil localization is an effective method for preoperative identification of small pulmonary nodules, enabling precise segmentectomy with high intraoperative accuracy.
