Indocyanine Green Fluorescence Angiography for Intraoperative Assessment of Blood Flow: A Feasibility Study

ObjectiveTo introduce our preliminary experience with indocyanine green (ICG) fluorescence angiography for the assessment of lower leg bypasses.Methods1 ml of 0.5% indocyanine green was intravenously injected in 9 patients with PAD who underwent paramalleolar artery bypass using saphenous vein grafts. A newly developed near-infrared camera system (PDE; Hamamatsu Photonics K.K. Hamamatsu, Japan) was used for this study.ResultsICG fluorescence...
