4 Fig. 3 A, Three-dimensional schematic representation of perianastomotic tissue vibration. B, and C, Schematic representations of longitudinal and transverse views of perianastomotic tissue vibration. See reference 11 for actual color figures.

5 Fig. 4 A, Mean pressures versus location for the end-to-side configuration. Note the pressure drops across the arterial and venous anastomoses. B, Mean pressures versus location for the end-to-end configuration. See text for details and statistical data. Pressures are significantly different for artery, graft, and vein in both configurations.

6 Fig. 5 Comparison of volumetric flow rates (VFR) for the end-to-side (ES) and end-to-end (EE) anastomoses over time. *VFR increases significantly between week 1 and week 4 for both configurations (p < 0.05). ES and EE configurations are statistically equivalent at each time period.

7 Fig. 6 Comparison of the volume of perivascular tissue vibration for the two anastomotic types over time. *Volume of perivascular tissue vibration increases significantly between week 1 and week 4 for both configurations (p < 0.05). ES and EE configurations are statistically equivalent at each time period.

8 Fig. 7 Amplitude of relative vessel wall motion versus anastomotic type for various locations at 1 and 12 weeks after implantation (see text for details). ES, End-to-side; EE, end-to-end anastomoses. 1 and 12 indicate weeks after implantation. *p < 0.05 for EE anastomosis at 12 weeks versus all other values at that location. †Relative wall motion for prosthetic graft is also statistically different from arterial and venous values (p < 0.05).

9 Fig. 8 Relative vessel wall velocity versus anastomotic type for various locations at 1 and 12 weeks after implantation (see text for details). Vein location numbers are shown in Fig. 2. a, Location just anterior to the vein; b, location just posterior to the vein. ES, End-to-side; EE, end-to-end. 1 and 12 indicate weeks after implantation. *p < 0.05 for ES 12 versus ES 1; **p < 0.05 for EE 12 versus all other data points.

10 Fig. 9 Venous intimal-medial thickness for end-to-side and end-to-end anastomotic types at 12 weeks after implantation. Numbers refer to vein location numbers shown in Fig. 3. Cntrl, Normal control vein. No statistical difference is noted between the two anastomotic types (see text).
