Synapse 3D With Intravascular Indocyanine Green

The 3D virtual models provided by Synapse 3D will be made by experts in medical image analysis using the high-resolution CT scans. Patients will have 3D virtual reconstructions of their pulmonary anatomy with the target lesion created pre-operatively.

ICG will be prepared as a sterile solution (2.5 mg/10mL) for injection. After vascular ligation, a 6 to 8mL bolus of ICG solution will be injected into the peripheral vein catheter, followed by a 10mL saline solution bolus. The Firefly camera will then be used for the NIF imaging. It is expected that the entire lung, except the segment which was previously isolated from blood supply, will fluoresce within 30-40 seconds, exhibiting a green hue. The surgeon will perform the pulmonary resection and the resected 'dark' lung segment will be immediately evaluated by a pathologist, depending on the pathologist findings the operation may be concluded or the patient will receive a pulmonary lobectomy.
