Prediction of flap necrosis with laser induced indocyanine green fluorescence in a rat model.
In this study, German researchers from Rechts der Isar Hospital in Munich used a rat model and ICG fluorescence to determine what level of perfusion gave good indication of future flap necrosis. In areas that would become necrotic they found that the perfusion rate was less than 25% than that of the surrounding area.
