4. Fig. 3
Doppler spectral tracings 12 weeks after implantation. 1, 2, and 4 refer to location numbers (Fig. 2). A specimens are from a 4 to 7 mm taper graft, B specimens are from a 6 mm untapered graft in the same animal as A, and C specimens are from a 7 to 4 mm taper graft.

5. Fig. 4
Color Doppler images of tissue vibration surrounding the superior vein (including locations 1 through 3) at 12 weeks after implantation. A, vein from a 4 to 7 mm taper graft; B, vein from a 6 mm untapered graft in the same animal as A; C, vein from a 7 to 4 mm taper graft; D, vein from a 6 mm untapered graft in the same animal as C. Grafts are at the top right and flow is from right to left in each picture. Vibration signals obscure portions of the vein near the graft.
