OBJECTIVE: To report a multi-center experience with the novel Hemodialysis Reliable Outflow (HeRO) vascular access graft.

MATERIALS AND METHODS: Four centers conducted a retrospective review of end stage renal disease patients who received the HeRO device from implant to last available follow-up. Data is available on 164 patients with an accumulated 2092.1 HeRO implant months.

RESULTS: At 6 months, HeRO primary and secondary patency is 60% and 90.8%, respectively and at 12 months, 48.8% and 90.8%, respectively. At 24 months, HeRO had a primary patency of 42.9% and secondary patency was 86.7%. Interventions to maintain or re-establish patency have been required in 71.3% of patients (117/164) resulting in an intervention rate of 1.5/year. Access related infections have been reported in 4.3% patients resulting in a rate of 0.14/1000 implant days.

CONCLUSIONS: In our experience the HeRO device has performed comparably to standard AVGs and has proven superior to TDCs in terms of patency, intervention, and infection rates when compared to the peer-reviewed literature. As an alternative to catheter dependence as a means for hemodialysis access, this graft could reduce the morbidity and mortality associated with TDCs and have a profound impact on the costs associated with catheter related infections and interventions.
