OBJECTIVES: The use of a hybrid operating room equipped with robotic C-arm cone-beam computed tomography for single-step localization and excision of small pulmonary nodules finds high cost barriers. The new generation of 3D C-arm system not only depicts soft tissues with high contrast but also offers a more affordable and sustainable solution. This approach has been chiefly applied in the field of orthopedic surgery. In this case series, we describe the use of a mobile 3D C-arm system for localizing and removing small pulmonary nodules.
METHODS: Between July and September 2020, we identified 14 patients who underwent localization and removal of small pulmonary nodules with a 3D C-arm system. We retrospectively reviewed clinical records to document the feasibility and safety of the procedure.
RESULTS: The median tumour size was 7.5 mm [interquartile range (IQR): 5 - 9.75 mm], with a median distance from the pleural surface of 4.2 mm (IQR: 0.5 - 6.45 mm). We successfully visualized all of the pulmonary lesions by intraoperative CT imaging. Localization was achieved in 13 patients, who subsequently underwent complete thoracoscopic resection. The median time required to localize lesions was 41.5 min (IQR: 33.75 - 53.25 min), with a median radiation exposure (expressed through the skin absorbed dose) of 143.45 mGy (IQR: 86.1 - 194.6 mGy). Failure to localize occurred in 1 patient because of pneumothorax caused by repeated needle puncture. All patients were successfully discharged and the median length of stay was 2.5 days (IQR: 2 - 3 days).
CONCLUSIONS: This case series demonstrates the feasibility of single-step localization and excision of small pulmonary nodules using a mobile 3D C-arm.
