While the mean bypass graft lumen increases about 22% over the first 6 months following implantation, A, considerable variability exists between individual grafts, B. Early luminal remodeling is correlated with initial shear stress at the time of implantation, C. Temporally distinct from luminal remodeling, the vein graft significantly stiffens between 1 and 3 months following implantation, D. Adapted from reference 10.
