Key result
Access flow was equal in arteriovenous grafts and fistulae (0.91 vs 0.91 L/min), but cardiac output, mean arterial pressure, and arterial segment resistance influenced flow in both types.
Why the study?
Do systemic hemodynamics affect flow within vascular accesses used for hemodialysis?
Population
Patients with 58 arteriovenous (AV) grafts and 35 autologous AV fistulae (AVF) used for hemodialysis
Comparison
Measurement of systemic hemodynamics vs AV grafts versus autologous AV fistulae
Design

May warrant considering hemodynamics in access evaluation; leaves open whether targeting them improves outcomes.

Do systemic hemodynamics affect flow within vascular accesses used for hemodialysis?
Absolute Event Rate: 0.91% vs 0.91%
Cardiac output, mean arterial pressure, and arterial segment resistance significantly influence hemodialysis access flow and must be considered when evaluating access dysfunction.
Besarab et al. (2001) conducted an observational in Hemodialysis vascular access (n=93). Arteriovenous (AV) grafts vs. Autologous AV fistulae (AVF) was evaluated on Access flow (L/min). Access flow was equal in arteriovenous grafts and fistulae (0.91 vs 0.91 L/min), but cardiac output, mean arterial pressure, and arterial segment resistance influenced flow in both types.
