We did a retrospective review of 83 femoropopliteal bypasses with grafting of saphenous vein performed for two groups of limbs: those with arteriosclerosis obliterans (n=71) and thromboangiitis obliterans (n=12) over the past 15 years. The purpose of the study is to assess factors that influence long-term graft patency. We also examined methods used for reoperation. After a mean follow-up of 35 months (ranges, 1-164), the cumulative patency rate was 79% at 5 years and again 79% at 8 years, which was better than the patency of PTFE grafts or other prosthetics reported by other authors. The two groups were compared for the severity of ischemia, condition of the outflow tract, and whether anastomosis was above or below the knee. These factors were different between the two groups, but the difference in patency was statistically not significant. Two reoperations for claudication were needed. One was carried out with use of the bilateral saphenous veins from below the portions used earlier. The other was done for obstruction of a PTFE graft; anastomosis was done at the mid portion with the use of Vitagraft.
