Recently developed fluorescence-navigated thoracoscopy with indocyanine green (ICG) is being used for various kinds of pulmonary surgery, and several studies have reported the application of this novel technique in demarcation of the intersegmental border for segmentectomy. This study is performed prospectively to find out, for the first time, the optimal dosage of ICG in human body to ensure safe and sustained imaging during segmentectomy.
