Table 1: Overview of animal models (species, location, AVF/AVG, diameters, flow values, patency, advantages/limitations). Abbreviations: AVF = arteriovenous fistula. AVG = arteriovenous graft. A = artery. V = vein. NIRF = near-infrared fluorescence. TEVG = tissue engineered vascular graft. IVUS = intravascular ultrasonography.
