FLOW: Flow dysfunction of hemodialysis vascular access: A randomized controlled trial on the effectiveness of surveillance of arteriovenous fistulas and grafts.

Introduction: It is assumed that identification and correction of asymptomatic stenoses in the vascular access circuit will prevent thrombosis that would require urgent intervention to continue hemodialysis treatment. However, the evidence base for this assumption is limited. Recent international clinical practice guidelines reach different conclusions on the use of surveillance for vascular access flow dysfunction and recommend further research to inform clinical practice.

Guideline recommendations on minimal blood vessel diameters and arteriovenous fistula outcomes.

Objective: Clinical guidelines provide recommendations on the minimal blood vessel diameters required for arteriovenous fistula creation but the evidence for these recommendations is limited. We compared vascular access outcomes of fistulas created in agreement with the ESVS Clinical Practice Guidelines (i.e.

Novel cannulation strategy with a bidirectional cannula for distal limb perfusion during peripheral veno-arterial extracorporeal life support: A preliminary, single-centre study.

Introduction: Limb ischemia is a severe complication of peripheral veno-arterial extracorporeal life support (V-A ECLS). Several techniques have been developed to prevent this, but it remains a major and frequent adverse event (incidence: 10-30%). In 2019, a new cannula with bidirectional flow (retrograde towards the heart and antegrade towards the distal limb) has been introduced.
