New 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 کاملNovel 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 کاملNew Insights into Dialysis Vascular Access: What Is the Optimal Vascular Access Type and Timing of Access Creation in CKD and Dialysis Patients?
Optimal vascular access planning begins when the patient is in the predialysis stages of CKD. The choice of optimal vascular access for an individual patient and determining timing of access creation are dependent on a multitude of factors that can vary widely with each patient, including demographics, comorbidities, anatomy, and personal preferences. It is important to consider every patient's...
متن کاملLifting the veil: insights into vascular access options.
In this issue of CJASN, Ong et al. (1) and Lok et al. (2) address two important issues on either end of the vascular access care spectrum. Lok et al. (2) evaluate data pertinent to choosing the optimal access for those patients initiating hemodialysis, including the autologous native arteriovenous fistula (AVF) versus the prosthetic arteriovenous graft (AVG). At the other end of the spectrum, O...
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...
