Abstract:
Indocyanine green (ICG) is a water-soluble biological fluorescent contrast agent with infrared absorption and emission characteristics. Indocyanine green angiography (ICGA) takes advantage of this biological property. After ICG is injected into the vascular system, the blood flow dynamic map is captured by high-speed photography or real-time photography, which can realize the visualization of vascular structure and tissue blood supply. Currently, ICGA is the only technique for intraoperative quantitative evaluation of flap blood perfusion, and it is widely used in plastic surgery and microsurgery. This review introduces the working principle and method of ICGA and its application in evaluating pedicled flap perfusion. According to the relevant literature reports at home and abroad in recent years, this review introduces the working principle and method of ICGA and its research progress in evaluating the blood perfusion of pedicled skin flaps. It is considered that this technique still has some limitations in method ology and accuracy of result, and it is still necessary to combine the clinical experience of doctors in the evaluation of tissue perfusion of pedicled skin flaps.
