Subjects will undergo infusion of 5 mg/kg indocyanine green, ICG ("TumorGlow") intravenously up to 5-days prior to surgery. Then, during the surgical procedure the next day, the subjects will undergo standard-of-care surgery. During the surgery, the fluorescence from the tumor will be used to localize lesions and ensure the entire tumor has been removed, as well as locate any un-expected tumors. The goal of this protocol is to evaluate safety and collect initial efficacy data using indocyanine green with NIR fluorescence imaging in a pediatric patient population undergoing pulmonary metastatectomy.
