Upper arm graft fistula for hemodialysis

The repeated failure of forearm hemodialysis access grafts in patients with end-stage renal failure often requires the use of an upper arm graft fistula. During a 7-year period, 20 upper arm graft fistulas were placed in 15 patients. The 5-year patency rate by life-table analysis, including graft fistula salvage by thrombectomy, is 53%. The mean survival from graft insertion until revision or thrombectomy is 36 months. Twenty of the twenty-two thrombectomies performed (91%) were successful in reestablishing graft fistula patency. Six grafts required more than one thrombectomy, and seven grafts required revision of the venous anastomosis. Only one arterial anastomosis required revision. We conclude that the upper arm graft fistula is an acceptable method of hemodialysis access in those patients without suitable forearm access sites. However, an aggressive approach to both graft fistula thrombectomy and the revision of stenotic anastomoses is necessary to maintain a satisfactory patency rate.
