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).

Fig. 3 dAVF suture line terminates at cephalad and caudad ends of parallel “otomies.” Journal of Vascular Surgery 1996 24, 240-248DOI: (10.1016/S0741-5214(96)70099-X) Copyright © 1996 Society for Vascular Surgery and International Society for Cardiovascular Surgery, North American Chapter Terms and Conditions
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.

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 < 0.0001 for 1979-83 vs 1990-95; p = 0.0007 for 1984-89 vs 1990-95).

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 1990-95 experience compared with the two previous series (p = 0.0016 for 1979-83 vs 1990-95; p = 0.0082 for 1984-89 vs 1990-95).
