Real-time fluorescence imaging with the ENDOCAM Logic 4K platform

Richard Wolf's System green is an outstanding real-time ICG/NIR fluorescence imaging solution that meets the highest standards in endoscopic imaging. Indocyanine green (ICG, available as Verdye in many regions*) is a tricarbocyanine dye that fluoresces when used with an NIR camera system, allowing anatomical structures to be visualized.

ICG/NIR fluorescence imaging has become one of the most valuable techniques in minimally invasive surgery. Applications include intraoperative assessment of visceral perfusion (e.g. in bowel anastomosis), visualization of bile duct structures in fluorescence cholangiography and lymph node mapping in oncological surgery (e.g. visualizing sentinel lymph nodes in lymphadenectomy).

*Diagnostic Green is a leading global supplier of high-quality fluorescence products, including ICG. Full prescribing information for Verdye is available at: https://diagnosticgreen.com/row/product-information/

Simultaneous ICG/NIR and white light endoscopy with sharp images

White light

System green supports standard white light endoscopy with high-resolution image quality at all times, so the system can be used without restriction in white light mode too.

greenICG

In greenICG mode, the conventional white light endoscopic image is combined in real time with ICG/NIR image information at the push of a button. This differentiates tissue with a high level of detail and contrast, so surgeons can easily distinguish anatomical structures during surgery.

greenICG pure

greenICG pure mode allows specific high-contrast visualization and differentiation of tissue structures, for example lymph nodes and lymphatic vessels. Grayscale visualization allows detailed examination of critical structures.

How fluorescence works

After administration, ICG enters the bloodstream, binds immediately to plasma proteins and circulates throughout the vascular system. The absorption spectrum of ICG (indocyanine green, Verdye, Diagnostic Green) is in the near-infrared (NIR) range: ICG absorbs light between 600 nm and 900 nm and emits fluorescence between 800 nm and 850 nm. An ICG/NIR camera system such as System green is used to visualize the ICG fluorescence, so it can be detected and visualized during surgery. NIR light allows surgeons to see structures more clearly.

ICG information

Indocyanine green (ICG, known as Verdye, Diagnostic Green)

Indocyanine green (ICG) is a tricarbocyanine dye that is both hydrophilic and lipophilic. Before use, the powder must be reconstituted with water for injection. Verdye is suitable for intravenous (i.v.) injection via injection needle, central or peripheral catheter or cardiac catheter. After i.v. injection, ICG binds rapidly to plasma proteins, with beta-apolipoprotein B as the main carrier (95%), and remains in the blood vessels.

ICG is cleared completely by the liver and excreted in the bile. ICG is not metabolized.
