Reduction in arteriovenous graft impairment: results of a vascular access surveillance protocol
AV Cayco, AK Abu-Alfa, RL Mahnensmith… - American journal of …, 1998 - ajkd.org
Impairment of hemodialysis (HD) vascular access, remains a frustrating problem for both the
patient who possesses an arteriovenous graft (AVG) and the nephrologist who cares for the
patient. We instituted a vascular access surveillance protocol intended to detect and correct
evolving stenosis in patients with AVGs. The principal screen was the observation of
dynamic venous pressure (VP) at a blood flow rate of 200 mL/min during the first 5 minutes
of each HD session. If VP at a blood flow rate of 200 mL/min was 140 mm Hg or greater in …
