Despite the pre-operative availability of well-defined criteria to create a primary arteriovenous fistula (AVF) a high early failure/missing maturation is complained worldwide. Based on new results from basic research using numerical techniques, the authors try to guide attention to a widely neglected field in published data: the unremarkable, small, but essential surgical details in creating a...

Arteriovenous fistula (AVF) failure is mainly due to venous stenosis characterized by significant amount of intima-media thickening (IMT), probably in the presence of negative (inward) remodeling. Our hypothesis is that the longitudinal changes in wall shear stress (WSS) within different configurations of AVF can influence remodeling factors (changes in luminal diameter (ΔDh ) and IMT) during i...

Arteriovenous fistulas (AVFs) used for hemodialysis fail because of venous neointimal hyperplasia (VNH). There are 1,500,000 patients that have end stage renal disease worldwide and the majority requires hemodialysis. In the present study, the role of the intermediate early response gene X-1 (IEX-1), also known as IER-3 in the pathogenesis of VNH was evaluated. In human samples removed from fai...

A progressive rise in the number of patients accepted for renal replacement therapy has been reported world wide [1]. Permanent vascular access (VA) is the life-line for the majority of these patients, when hemodialysis is the treatment of choice. Thus, the successful creation of permanent vascular access and the appropriate management to decrease the complications is mandatory. A well function...

Radiocephalic arteriovenous fistulas (AVFs) are often criticized for requiring numerous recurrent interventions to achieve and maintain hemodialysis access function. Recent Kidney Disease Outcomes Quality Initiative guidelines discourage ongoing salvage attempts after two prior successful use or more than three per year overall. This study's goal was develop a useful prediction tool preoperativ...

Ischemic monomelic neuropathy (IMN) is an under-diagnosed and disabling complication of upper extremity hemodialysis access. The hemodynamic disturbance that occurs during the time of access creation can lead to both neurologic and ischemic complications. These complications are most commonly seen following proximal procedures involving the upper limbs. Diagnosis and treatment are often delayed...

The radiocephalic arteriovenous fistula (AVF) provides optimal vascular access for hemodialysis; it has a higher long-term patency rate and fewer complications than other vascular access methods. However, the AVF has a high primary failure rate. The presence of small-diameter vessels at anastomosis sites is an important risk factor for AVF failure. However, in a recent study, despite selecting ...

Anaesthetic modalities for arteriovenous fistula (AVF) creation include general (GA), local (LA) and regional anaesthesia (RA). Ultrasound guided (USRA) proved to have more benefits in AVF than the other two. This study conducted at Douala General Hospital aimed assess these over GA RA. A retrospective review was performed on 217 records of patients who underwent an between January 2015 Decembe...

BACKGROUND The patency of arteriovenous access is important for stable and effective hemodialysis, and long-term technical survival is best achieved with a native arteriovenous fistula (AVF). However, maintaining AVF patency remains a challenge. This study was designed to determine the independent prognostic factors for AVF patency according to hemodialysis duration. METHODS The primary study...

The arteriovenous fistula (AVF) is the preferred access for haemodialysis [1]. However, AVF failure has become more common over the last three decades as more patients are older, and have diabetes or vascular disease. For radiocephalic AVF, a meta-analysis estimated modest primary (63%) and secondary (66%) patencies at 1 year [2]. AVF failures have been attributed to inadequate vessels used for...
