2. Fig. 1
Configurations of various dAVFs: A, common ostium (n = 280); B, proximal vein piggyback (n = 3); C, distal vein piggyback (n = 1); D, Vein interposition (VI) (n = 2); E, Remote side-to-side (n = 4); F, Proximal side-to-side (not used in this series).

3. Fig. 2
Current method for performing common ostium dAVF. Arteriotomy and venotomy are established at 10 and 2 o'clock (A and C). Side-to-side anastomosis is begun at midpoint of “posterior” wall (B).

5. Fig. 4
Small incisions (nicks) in each quadrant convert common ostium into rectangular shape, helping to avoid twisting of subsequent graft anastomosis. Interrupted sutures (2 or 3) in each quadrant avoid stenosing anastomosis and fistula.

6. Fig. 5
Life-table patency rates for femoral crural prosthetic grafts (predominantly umbilical vein) with dAVF. Steady improvement is noted over the three time periods, with statistical significance established for the 1990 to 1995 experience compared with the previous two series (p < for vs ; p = for vs ).

7. Fig. 6
Life-table limb salvage rates for femoral crural prosthetic grafts (predominantly UV) with dAVF. Steady improvement is noted over the three time periods, with statistical significance established for the experience compared with the two previous series (p = for vs ; p = for vs ).
