2 Fig. 1 Comparison of the overall primary patency rates for each of the four graft types: RS, reversed saphenous; IS, in situ; PTFE, polytetrafluoroethylene; UV, modified human umbilical vein. All curves are different from one another with p < 0.01 or less.

3 Fig. 2 Primary patency rates for autogenous vein grafts (IS + RS = 78% at 3 years) are significantly better than for nonautogenous grafts (PTFE + UV = 31%) when the distal anastomosis was to the below-knee popliteal artery (p < 0.001).

4 Fig. 3 Primary patency rates for autogenous vein grafts (IS + RS = 78% at 3 years) are significantly better than for nonautogenous grafts (PTFE + UV = 10%) when the distal anastomosis was to the peroneal or tibial arteries (p < 0.001). This difference is greater than observed at the below-knee popliteal level (see Fig. 2).

5 Fig. 4 For femorotibial bypass, the in situ graft (IS = 88%) gave significantly better patency than reversed saphenous vein (RS = 63%) (p < 0.05 at 36 months).

6 Fig. 5 Comparison of the cumulative hazard rates for risk of failure for each of the four grafts studied.

7 Fig. 6 Tobacco use had a significant deleterious effect on overall graft patency (p < 0.05). Journal of Vascular Surgery 1988 8, DOI: ( / (88)90273-X) Copyright © 1988 Society for Vascular Surgery and International Society for Cardiovascular Surgery, North American Chapter Terms and Conditions

8 Fig. 7 Diabetic patients enjoyed a significantly better overall primary patency rate than nondiabetics (p < 0.02) for reasons detailed in the text and in Tables III and IV.

9 Fig. 8 The protective effect of dextran 40 infusions on graft patency waned during the 3-year follow-up. It appears to be sustained at 32 months in PTFE and UV grafts, but by this time statistical significance is lost (log rank test).
