Seven kinds of graftings for creation of hemodialysis blood access were used, and the comparison of graft materials and technics was made with their patency and utility. Graftings compared were as follow: 1) Autogenous vein graft, 2) Expanded-PTFE, 3) Modified bovine arterial graft, 4) Modified swine arterial graft, 5) Composite graft of bovine graft and expanded-PTFE, 6) Composite graft of swine graft and expanded-PTFE, and 7) Superficially replaced saphenous vein graft. Superficially replaced saphenous vein graft was the most satisfactory and remained patent for longer period of time. The advantages are; 1, ease of construction, only one anastomosis is necessary. 2. ease of canulating the fistula even in the obese patient. 3. allowing an immediate use of the fistula for hemodialysis after construction. We have found this method as the first procedure of choice in those patients who have no available site in the upper extremities for construction of a fistula.
