Screening for hemodialysis graft stenosis and short-term thrombosis risk: A comparison of the available tools

Nicola Tessitore, Giovanni Lipari, Alberto Contro, Francesca Moretti et autres

INTRODUCTION: Guidelines recommend hemodialysis graft screening to identify and repair significant (>50%) stenosis at high risk of thrombosis, but there is insufficient evidence to prefer one or other screening tool due to the lack of studies comparing all available options. METHODS: Seeking …

FP649IN SEARCH OF AN OPTIMAL SCREENING PROGRAM FOR DETECTING STENOSIS AND PREDICTING THROMBOSIS IN ARTERIOVENOUS GRAFT: A DIAGNOSTIC COMPARATIVE ANALYSIS OF THE CURRENTLY AVAILABLE TOOLS

Nicola Tessitore, Giuseppina Pessolano, Valeria Bedogna, Giovanni Lipari et autres

INTRODUCTION: Guidelines recommend routine screening of arteriovenous grafts for timely detection and elective repair of significant (>50%) stenosis (ST) at high risk of thrombosis by surveillance (access blood flow [Qa], static venous pressure ratio [sVPR] or Duplex Ultrasound [DU]) or clinical monitoring …

Pro: Vascular access surveillance in mature fistulas: is it worthwhile?

Nicola Tessitore, Albino Poli

Guidelines recommend regular screening of mature arteriovenous fistulas (AVFs) for preemptive repair of significant stenosis (≥50% lumen reduction) at high risk of thrombosis, identifiable from clinical signs of access dysfunction (monitoring) or by measuring access blood flow (Qa surveillance), which also enables …

A single dialysis session of hemodiafiltration with sorbent-regenerated endogenous ultrafiltrate reinfusion (HFR) removes hepcidin more efficiently than bicarbonate hemodialysis: a new approach to containing hepcidin burden in dialysis patients?

Nicola Tessitore, Albino Poli, Valeria Bedogna, L. Corazza et autres

BACKGROUND: Most hemodialysis patients have high Hepcidin-25 levels, which may be involved in the pathogenesis of several uremic complications related to an altered iron biology. The hemodialysis procedure itself can influence Hepcidin-25 levels by removing Hepcidin-25 and maybe stimulating its production due …

SP509IN SEARCH OF AN OPTIMAL SCREENING PROGRAM FOR DETECTING STENOSIS AND PREDICTING INCIPIENT THROMBOSIS IN ARTERIOVENOUS GRAFTS

Nicola Tessitore, Giuseppina Pessolano, Valeria Bedogna, Albino Poli et autres

Introduction and Aims: Guidelines recommend that grafts should be screened for >50% stenosis (St) by surveillance (access blood flow [Qa], static venous pressure ratio [VAPR] or Duplex Ultrasound [D]) stating that there is insufficient evidence to prefer one technique from the other …

FP697A COHORT EFFECT COMPATIBLE WITH LIFESTYLE CHANGES IS A MAJOR DETERMINANT OF THE INCIDENCE OF END STAGE RENAL DISEASE (ESRD) IN THE ELDERLY NORTH-EASTERN ITALIAN POPULATION DURING THE PERIOD 1998-2012

Maurizio Nordio, Nicola Tessitore, Cataldo Abaterusso, Mariano Feriani et autres

Introduction and Aims: The incidence of ESRD is heavily affected by the ageing of the population. The effect of ageing may be split into three mechanisms: age at the presentation of ESRD (age effect), exposure to environmental or behavioral risk factors occurring …

Clinical Access Assessment

Nicola Tessitore, Valeria Bedogna, Giovanna Verlato, Albino Poli

BACKGROUND: Vascular access guidelines recommend routine screening for the timely detection of stenosis using noninvasive methods, including clinical assessment (monitoring) and device-based surveillance relying on access blood flow (Qa) and static intra-access pressure (sVPR, static venous pressure ratio) measurements and duplex ultrasound …

The Rise and Fall of Access Blood Flow Surveillance in Arteriovenous Fistulas

Nicola Tessitore, Valeria Bedogna, Giuseppe Verlato, Albino Poli

Vascular access blood flow (Qa) surveillance has been described as a typical false paradigm, an example of how new tests are sometimes adopted even without good-quality evidence of their benefits. This may be true for grafts, but not necessarily for arteriovenous fistulas. …

Should current criteria for detecting and repairing arteriovenous fistula stenosis be reconsidered? Interim analysis of a randomized controlled trial

Nicola Tessitore, Valeria Bedogna, Albino Poli, Giovanni Lipari et autres

BACKGROUND: The vascular access guidelines recommend that arteriovenous fistulas (AVFs) with access dysfunction and an access blood flow (Qa) <300-500 mL/min be referred for stenosis imaging and treatment. Significant (>50%) stenosis, however, may be detected in a well-functioning AVF with a Qa …
