Over the past decade a new emergent technology has become very popular in all fields of surgery using Indocyanine green and near infrared fluorescent optical systems. This revolutionary approach overlaps conventional and near infrared images to produce highly informative intraoperative images on the anatomy and physiology of various tissues. Near infrared fluorescence is employed for perioperative angiography in vascular mapping, assessment of anastomoses, location of sentinel lymph nodes and delineation of biliary tree anatomy, highlighting tumours and metastatic deposits, improving surgical techniques and for many other uses. A lot of researchers have reported better surgical outcomes and technique innovations facilitated by this novel technology which although in its early stages, it lights up great interest worldwide. This article reviews the principle of the method, the properties of the fluorescent dye, the main clinical applications and discusses future research directions.
