The straight radial-antecubital PTFE angio-access graft in an era of high-flux dialysis

Straight radial-antecubital polytetrafluoroethylene (PTFE) grafts were placed in 10 older (greater than 55 years) male patients with significant inter-current diseases who were considered candidates for high-flux dialysis. Graft patency was 90% at 6 months, and suitable flow for high-flux dialysis (greater than 400 mL/minute) could be achieved with all grafts. Shorter dialysis times with no major cardiovascular, hemodynamic, or extremity complications were achieved with this mode of therapy. The principles and practicalities of high-flux dialysis are reviewed. This small series of patients demonstrates that the relatively low resting flow of the straight radial-antecubital PTFE graft should not be a major consideration in the choice of this vascular access procedure in patients being considered for high-flux dialysis. Straight radial-antecubital PTFE grafts preserved both the ulnar collateral to the hand and the brachial artery for later access, yet provided adequate flow in all patients in whom they remained patent.
