Measurement of the graft: (A) the mid-diameter of the graft measured at the midpoint after triple folding using a digital vernier caliper, (B) the peripheral diameter measured at the end of the graft after triple folding using a graft sizer, and (C) the length of the graft measured from end to end after triple folding using a digital vernier caliper (D) the length of graft before folding.
