The juxta-anastomotic stenosis of an arteriovenous fistula (AVF) is a significant clinical problem in hemodialysis patients with no effective treatment.

2015年9月23日 · A major cause of fistula nonmaturation is juxta-anastomotic stenosis (JAS) . JAS is variably defined in the literature as a more than 50% reduction of the luminal diameter of the outflow vein within 2 cm or 5 cm from the arteriovenous anastomosis.

Purpose: Juxta-anastomotic stenosis (JAS) is a complication of arteriovenous fistulas (AVFs). Both surgical revision (SR) and percutaneous transluminal angioplasty (PTA) may correct JAS. In this study we compare the results for SR treatment versus PTA.

2011年5月10日 · Juxta-anastomotic stenosis (JAS) is one of the predominant causes of arteriovenous fistula (AVF) failure, with the reported incidence as high as 65%. We hypothesized that technical modification to alter the outflow vein configuration using the novel piggyback Straight Line Onlay Technique (pSLOT) would prevent JAS and improve AVF maturation.

To evaluate long-term results of endovascular procedures in treatment of venous juxta-anastomotic stenoses (JASs) of native forearm radiocephalic arteriovenous fistulas (AVFs) and to identify prognostic factors influencing these results.

To eliminate juxta-anastomotic stenosis and to promote improved maturation rates of AVFs, we placed a covered endograft into the juxta-anastomotic vein segment at the time of AV fistula creation: the JuxtaBahn procedure.

The most common lesion is juxta-anastomotic stenosis. Systemic factors such as hypotension, higher hemoglobin target, 59 and hypercoagulabiity 60 result in increased risk of access thrombosis for both fistulas and grafts.

2024年11月26日 · The juxta-anastomotic stenosis (JAS) represents the major complication of arteriovenous fistula (AVF) during the first months after the surgery and the approach to JAS can be surgical or radiological.

Juxta-anastomotic (or inflow) stenosis is the most common reason leading to primary failure, and percutaneous transluminal angioplasty (PTA) continues to be the gold standard treatment with excellent success rates.

2019年6月28日 · Stenosis is the number one cause of dysfunction in an arteriovenous (AV) fistula. (i) Evidence suggests that stenosis causes 78 percent of all cases of early AV fistula failure and is also the most common cause of late AV fistula failure after three months.
