However, prevalence rates of native AVFs are variable around the world and have increased only slightly in United States since the DOQI guidelines. To increase rates of native AVFs, pre-operative vascular mapping by(More)
Long-term catheters are widely used in some dialysis units. Because of higher dialysis dose targets, high flow catheters have been made available. We measured blood flow (Qb in ml/min) and recirculation rate (R%) in two types of tunneled dialysis catheters using ultrasound-dilution technology (Transonic). Thirty-seven catheters were evaluated (27 Opti-Flow,(More)
