Haemodialysis vascular access and fistula surveillance methods in The Netherlands

Abstract

The use of PTFE grafts and other types of vascular accesses has increased at the expense of BC fistulas. Recirculation and venous pressure measurements are primarily done when problems occur and not according to a standard surveillance schedule. For visualization of failing fistulas, 79% of the centres uses Duplex ultrasound analysis and 100% angiography. The popularity of PTA has increased from 46 to 92% of the centres.

Effects of venous needle turbulence during ex vivo hemodialysis on endothelial morphology and nitric oxide formation

“…Flow disturbances created by the graft-vein anastomosis have been implicated in the pathogenesis of IH, but many attempts made to improve graft patency by modifying the geometry of the anastomosis were unsuccessful (Dilley et al, 1992;Dobrin et al, 1989;Ezzahiri et al, 1999;Fillinger et al, 1990;Hakim and Himmelfarb, 1998;Kanterman et al, 1995;Loth et al, 2003). In contrast, the role of the return needle turbulence during the hemodialysis process and its implications in the pathogenesis of VNH remains relatively unexplored (Zarate, 1998).…”

Using Cuffed and Tunnelled Central Venous Catheters as Permanent Vascular Access for Hemodialysis: A Prospective Study

“…But no current access type fulfils all of these criteria. [3][4][5] Native arteriovenous fistula is the first preference for PVA because different studies demonstrate that NAVF have the best patency rates and require the fewest interventions compared to other VA modalities. But in recent years, using NAVF has been reduced according to using GAVF and CVCs in the United States, due to the increasing survival of patients with chronic renal failure treated with hemodialysis and the increasing quantity of diabetics and of elderly patients.…”

Long-term survival of arteriovenous fistulas in home hemodialysis patients

“…The prevalence of AV fistulas in dialysis patients varies throughout the world [8,[9][10][11]17] and within countries [8,18]. The highest rates of AV fistula use are in Japan, Europe [8,18], and Australasia [11] (60% to 90%), and the lowest rates are in the United States (20% to 24%) [8,17].…”

“…The proportion of HD patients who use an AV fistula varies throughout the world, from 24% in the United States [8], 62% to 85% in Europe [8][9][10], and 81% and 63% in Australia and New Zealand, respectively [11]. The possible reasons for these differences in AV fistula use are both patient and physician specific.…”
