“…Imaging assessment of an access can be performed using ultrasound and/or fistulography (27,28). Doppler ultrasonography is an accurate tool for identifying the presence, location, and severity of access stenosis, but it is not sensitive and specific enough to reliably quantify access flow (27,29,30).…”

AR = access recirculation, AVF = arteriovenous fistula, AVG = arteriovenous graft, DHIS = distal hypoperfusion ischemia syndrome, KDOQI = Kidney Disease Outcomes Quality Initiative, NKF = National Kidney Foundation, Qa = blood access flow rate PREAMBLE The membership of the Society of Interventional Radiology (SIR) Standards of Practice Committee represents experts in a broad spectrum of interventional procedures from both the private and the academic sectors of medicine. Generally, Standards of Practice Committee members dedicate the vast majority of their professional time to performing interventional procedures; as such, they represent a valid broad expert constituency of the subject matter under consideration for standards production. Technical documents specifying the exact consensus and literature review methodologies as well as the institutional affiliations and professional credentials of the authors of this document are available upon request from SIR, 3975 Fair Ridge Dr, Ste 400 North, Fairfax, VA 22033. METHODOLOGY SIR produces its Standards of Practice documents using the following process. Standards documents of relevance and timeliness are conceptualized by the Standards of Practice Committee members. A recognized expert is identified to serve as the principal author for the standard. Additional authors may be assigned depending on the magnitude of the project. An in-depth literature search is performed using electronic medical literature databases. Then a critical review of peer-reviewed articles is performed with regard to the study methodology, results, and conclusions. The qualitative weight of these articles is assembled into an evidence table, which is used to write the document such that it contains evidence-based data with respect to content, rates, and thresholds. When the evidence of literature is weak, conflicting, or contradictory, consensus for the parameter is reached by a minimum of 12 Standards of Practice Committee members using a Modified Delphi Consensus Method (Appendix A). For purposes of these documents, consensus is defined as 80% Delphi participant agreement on a value or parameter. The draft document is critically reviewed by the Revisions Subcommittee members of the Standards of Practice Committee, either by telephone conference calling or by face-to-face meeting. The finalized draft from the Committee is sent to the SIR membership for further input or criticism during a 30-day comment period. These comments are discussed by the Subcommittee, and appropriate revisions are made to create the finished standards document. Before its publication, the document is endorsed by the SIR Executive Council.

“…Intraoperative blood flow measurements greater than 120 ml/min in AVF and less than 320 ml/min in AVGs may be predictive factors of early failure and fistulography is essential to access patency [155]. In addition to the clinical examination, there are numerous radiological assessments of vascular access pre-and postoperative that enrich our diagnostic armamentarium [156]. Recently, Remuzzi and Manini [157] presented a numerical model that in the clinical setting should allow to reduce the incidence of AVF nonmaturation as well as incidence of VA complications.…”

“…Failed maturation is associated with puncture-related complications and/or insufficient dialysis, which can lead to permanent loss of the fistula. Further diagnostic examinations should be performed if fistula maturation is not completed within eight weeks to enable prompt diagnosis and treatment (6, 9, 10). Frequent underlying causes of non-maturation are venous, arterial or anastomotic stenosis (11, 12).…”

Impaired fistula maturation is associated with puncture-related complications, insufficient dialysis and potential permanent access failure. Non-maturation is frequently initiated by stenotic vascular access vessels comprising the outflow veins, the arteriovenous anastomosis and infrequently the inflow artery. Further findings in maturation protraction are central venous stenoses or accessory outflow veins. Depending on the underlying pathology, several endovascular approaches to boost fistula maturation are possible. To date standard balloon angioplasty remains the primary proven treatment option.
