Patients with lower extremity dialysis access have poor primary patency and survival

Objective Lower extremity arteriovenous (AV) access is an alternative when upper extremity access options have been exhausted. Our goal was to assess short- and medium-term outcomes of lower extremity hemodialysis access. Methods The Vascular Quality Initiative was reviewed for all lower extremity AV hemodialysis cases. Patient and case details were recorded. Multivariable analysis was used to analyze outcomes. Results We identified 463 lower extremity AV access cases in the VQI registry. There were 56 AVF (12.1%) and 407 AVG (87.9%). The mean age was 56 ± 15 years, 46.9% were male, and 40.7% were Caucasian. The majority (90%) had a previous upper extremity AV access and 25.4% had a prior lower extremity access. More than one-half (57.9%) had a tunneled line at the time of the procedure. Patients undergoing an AVF vs AVG creation were younger, more often ambulatory, and less often with peripheral arterial disease. For AVF, the superficial femoral artery was more often used for access inflow (76.8% vs 49.4%; P Conclusions In our contemporary multicenter analysis, patients undergoing lower extremity AV access creation have low primary access patency and almost 20% mortality at 1 year. These results should be considered when suggesting a lower extremity dialysis access, as well as other dialysis alternatives when available.
