Pathogenesis and Prevention of Vascular Access Failure

Abstract

Dialysis vascular access failure is common, is rated as a critical priority by both patients and health professionals, and is associated with excess morbidity, mortality and healthcare costs. This chapter will discuss the mechanisms underpinning vascular access failure as well as strategies for preventing this adverse outcome, including systemic medical therapies (such as antiplatelet agents, fish oils, statins, inhibitors of the renin-angiotensin-aldosterone system, and calcium channel blockers), and local therapeutic interventions including innovative surgical techniques, minimally invasive AVF creation, far infra-red therapy, perivascular application of recombinant elastase, endothelial loaded gel foam wrap (Vascugel), and antiproliferative agents such as sirolimus (Coll-R) and paclitaxel-coated balloon angioplasty.
