Indocyanine Green is an imaging dye that is used in liver and heart procedures. The utilization of this dye as color depends on its location in the body. This is mostly used in medical diagnostics to determine cardiac output, hepatic function, as well as liver and gastric blood flow, and is also used ophthalmic angiography. It has a range of about 800 nm in terms of its spectral absorption.
There are some recent video imaging studies that have been done using indocyanine green. And through it, indocyanine green was noted as one of the major factors that contribute to decision making during surgery. There are many clinical applications of indocyanine green (ICG) enhanced fluorescence in laparoscopic surgery. Intraoperative or injection-related adverse effects may occur, yet it gives a clear identification to biliary/vascular anatomy. The imaging system, with the use of indocyanine green, provides invaluable information to surgeries, as there are no injuries nor anastomotic leaks reported. Others found this as a safe, simple and useful imaging dye. This dye will be a more useful standard in the coming years with its different diagnostic and oncological capabilities. Larger studies and more specific evaluations are needed to confirm its role and to address its disadvantages.
