Descriptive results of indocyanine green-videoangiography (ICG) with integrated FLOW 800 tool. First and second maximum (A,B), maximal in-/decrease (C,D), and the area under the curve (AUC) (E,F) were analysed simultaneously at three regions of interest (ROI) (pre- and poststenotic, and accompanying artery/vein) at varying degrees of stenosis at the A. and V. femoralis. ICG intensity was registered for each parameter in arbitrary units [AU].
