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

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) has been designed. The aim of this study was to provide preliminary evidence of VasQ impact on AVF hemodynamics as compared to AVFs created with conventional surgery.
