Real time imaging during solid organ transplant


A method of determining the patency of a donor organ or at least one vessel to a donor organ in a donor subject includes administering a fluorescent dye to the donor subject, applying a sufficient amount of energy to the vessel such that the fluorescent dye fluoresces, obtaining a fluorescent image of the donor organ or the vessel attached to a donor organ, and observing the image to determine if a fluorescent signal is continuous through the vessel. A continuous fluorescent signal in the donor organ or vessel indicates the respective donor organ or vessel is patent.
