Early recognition and management of inappropriately high-flow AV access is an important aspect of medical care delivered to the hemodialysis patient. The clinical features, diagnosis, and management of the high-flow AV access are reviewed. Other complications related to AV access are reviewed separately.

In the USA, 80% of patients with CKD begin treatment with a HD catheter, while only 16.9% use it by arteriovenous fistula (AVF), and 3% by arteriovenous graft (AVG) . At the end of 2014, the prevalence of AVF was 63.4% in dialysis patients .

A well-functioning vascular access (VA) is a mainstay to perform an efficient hemodialysis (HD) procedure. There are three main types of access: native arteriovenous fistula (AVF), arteriovenous graft, and central venous catheter (CVC). AVF, described by Brescia and Cimino, remains the first choice for chronic HD.

It is important to diagnose recirculation in order to optimize dialysis delivery. In addition, screening for recirculation may be used as a surveillance technique for the early detection of fistula stenosis, the correction of which may prevent thrombosis. This …

2021年5月6日 · This review provides an overview of the advances in technology relevant to hemodialysis vascular access. The primary focus is on newer devices used to create a minimally invasive arteriovenous fistula (AVF), a promising alternative to synthetic arteriovenous graft (AVG), and devices to bypass a central vein stenosis/occlusion.

2024年12月3日 · An AVF, created by an anastomosis between a native artery and a vein, is the recommended vascular access for patients requiring HD due to its substantially lower rates of thrombosis, infection, and health care–related expenditures compared with AVG and CVC, if the AVF successfully matures for dialysis use.

Native arteriovenous fistula (AVF) is the vascular access of choice for hemodialysis patients. Compared with grafts and central venous catheters, AVFs last longer and are associated with fewer complications.

5 天之前 · As a result, arteriovenous access (AVa), which includes AVF and AVG, is currently recommended as the preferred vascular access for the general HD population according to clinical practice guidelines [17, 18]. However, AVa, particularly AVF is more commonly placed in younger patients with fewer comorbidities.

2023年12月3日 · Arteriovenous fistula (AVF) is the first choice of vascular access in hemodialysis (HD) patients. However, the correlations between patient factors and the arteriovenous fistula...

Background: Arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis (HD). However, primary AVF dysfunction represents a major barrier to the long-term success of HD therapy. This study aims to analyze the variables that …
