Novel paradigms for dialysis vascular access: Introduction.
Nonmaturation of new arteriovenous fistulas (AVFs) remains a major barrier to increasing AVF use in hemodialysis patients (1). Our current clinical paradigmviews nonmaturingAVF as a plumbing problem, with efforts directed at augmenting access flow by surgical or percutaneous interventions (2–4). Unfortunately, the very same interventions utilized to salvage immature fistulas also result in vasc...
متن کاملNovel paradigms for dialysis vascular access: upstream hemodynamics and vascular remodeling in dialysis access stenosis.
Failure of hemodialysis access is caused mostly by venous intimal hyperplasia, a fibro-muscular thickening of the vessel wall. The pathogenesis of venous neointimal hyperplasia in primary arteriovenous fistulae consists of processes that have been identified as upstream and downstream events. Upstream events are the initial events producing injury of the endothelial layer (surgical trauma, hemo...
متن کاملNovel paradigms for dialysis vascular access: downstream vascular biology--is there a final common pathway?
Vascular access dysfunction is a major cause of morbidity and mortality in hemodialysis patients. The most common cause of vascular access dysfunction is venous stenosis from neointimal hyperplasia within the perianastomotic region of an arteriovenous fistula and at the graft-vein anastomosis of an arteriovenous graft. There have been few, if any, effective treatments for vascular access dysfun...
متن کاملNew Insights into Dialysis Vascular Access: Introduction.
Optimizing vascular access outcomes continues to pose a tremendous challenge to nephrologists, surgeons, and radiologists who provide medical care to patients on hemodialysis. There is a huge discrepancy between the optimal vascular access outcome proposed by national guidelines (1) and the reality. Thus, for example, whereas the guidelines suggest that most patients should initiate hemodialysi...
متن کاملEndovascular Techniques for Dialysis Vascular Access
A nephrologist is well equipped to understand and manage the complexities involved in educating and preparing a patient with chronic kidney disease to embrace the challenges involved with renal replacement therapy. The importance of vascular access in providing adequate dialysis therapy cannot be overemphasized. Unfortunately, it remains a weak link in providing optimal care and a major cause o...
