We evaluated the efficacy and safety of ultrasound-guided...

... affects morbidity and mortality. Historically, native arteriovenous fistulas (AVFs) have been established using surgical techniques. However, devices facilitating percutaneous endovascular arteriovenous fistula (endoAVF) formation have recently been introduced in clinical practice, showing promising...

... of evidence regarding the optimal timing of vascular access creation in predialysis patients. Methods: Our study prospectively enrolled 300 patients undergoing predialysis arteriovenous fistula (AVF) creation in our center from 2015 to 2018. Cox proportional hazard regression was performed to identify which...

...Francini Porcher Andrade; Talmir Nolasco; Marli Maria Knorst; Paula Maria Eidt Rovedder Introduction: A healthy arteriovenous fistula (AVF) depends on adequate vessel diameter which can be maintained through aerobic exercises. A randomized crossover study was conducted to evaluate the acute effects...

.... Some studies have suggested that the absolute value of the Pa pressure to the extracorporeal blood pump flow (Qb) ratio set on the machine (|Pa/Qb|) can reflect the dysfunction of VA. This study was conducted to explore the impact of arteriovenous fistula (AVF) dysfunction and to explore the clinical...

.... Autogenous arteriovenous fistula is the best angioaccess available but is hampered by its relatively high non-maturation rate. Guidelines recommend preoperative duplex ultrasonography (USG) and use of vessels with a diameter that is able to maintain sufficient flow and fistula maturation to avoid...

...Kehui Shi; Hongli Jiang; Masanori Wakabayashi Introduction: Plastic cannulas have been used to cannulate arteriovenous fistulas (AVFs) for hemodialysis (HD) in Japan for many years. However, the effect of early cannulation with plastic cannulas on AVF patency is not known. Objective: We analyzed...

Rosales; Hanjie Zhang; Marilou Mateo; Brenda Chan; Israel Campos; Nikolas Harbord; Stephan Thijssen; Peter Kotanko Background: The time between the creation of an arteriovenous fistula (AVF) and its successful use is significantly longer in hemodialysis (HD) patients in the United States...

...Arif Asif; Mohamed M. Bakr; Michael Levitt; Tushar Vachharajani Background: Conflicting data continue to surround the optimal dialysis access for the elderly. Many propose that catheters are the best option for this population; others emphasize the creation of an arteriovenous fistula. Summary...

... stenosis (BS). Results: Two hundred twenty-one arteriovenous fistulas (AVFs) were included: 58.8% had SS, 18.6% had BS, and 22.6% had no dysfunctional access (ND). SS had a significantly higher thrombotic events than BS and ND (13.1 vs. 4.4%, p = 0.018). The annual thrombosis rate was 0.007, 0.037...

... receiving twice-weekly maintenance HD for 4 h (intermittent HD); access was via an internal jugular line initially and then via a left brachiocephalic arteriovenous fistula (AVF) from late June 2013.

...Giordano Fumagalli; Stefano De Pietro; Massimiliano Migliori; Francesco Paolo Ferrandello; Fabio Trovato; Carlo Donadio; Vincenzo Panichi Background: Optimizing vascular access outcomes is still a challenge, since 30-60% of arteriovenous fistulas fail or do not mature and catheters are widely used...

...Krzysztof Letachowicz; Mariusz Kusztal; Tomasz Gołębiowski; Waldemar Letachowicz; Wacław Weyde; Marian Klinger Background: The native arteriovenous fistula (AVF) needs maturation before it can be used. Needling done before time may result in haematoma formation, miscannulation or even access loss...
