The utilization of 162 PTFE grafts for anglo access in 131 patients over a three year period is reported. One hundred and three new PTFE arterlo‐venous flstulae were constructed in addition to 59 patch and tube incorporations Into pre‐existing graft flstulae. At three years, the cumulative patency of newly constructed grafts was 85%. Seventy four per cent of the grafts have had no thrombosis and are functioning up to 38 months following insertion. An aggressive approach was adopted towards the 15% of grafts that had at least one episode of thrombosis prior to flow being successfully restored. Graft occlusion which occurred up to 18 months following Insertion, represented 11% of the group In this series. PTFE has provided an important advance In angio access for chronic renal failure with high patency and excellent durability after three years.
