Arteriovenous fistula creation with VasQ^TM device: A feasibility study to reveal hemodynamic implications.

ABSTRACT:

Background

Arteriovenous fistula (AVF) is the preferred vascular access (VA) for hemodialysis, but it is still affected by high non-maturation and early failure rates due to stenosis development. Increasing evidence suggests that the presence of turbulent-like flow may play a key role, therefore, to stabilize the flow in the venous segment, an external support device (VasQ^TM) has been designed. The aim of this study was to provide preliminary evidence of VasQ^TM impact on AVF hemodynamics as compared to AVFs created with conventional surgery.

Methods

In this pilot single-center prospective randomized study six patients were enrolled, three in the VasQ group and three in the control group. Contrast-free magnetic resonance imaging (MRI) scans were acquired
