Vascular ultrasound assessment of therapeutic efficacy. (A). Schematic diagram of molding using “Cuff” method. (B). Vascular ultrasound of the vein graft. (C). Vascular ultrasound evaluation of the diameter changes in the vein graft of each group of rabbits at 14 and 28 days. (D). Stenosis rate of vein graft in each group of rabbits at 14 and 28 days (n = 3). (E). Blood flow velocity of vein graft in each group of rabbits at 14 and 28 days (n = 3).
