Implantation of the external anastomotic VasQ\u2122 support device during AVF creation has been suggested to improve the functional outcomes of AVFs. In the current study, we report the clinical outcomes when using the device with radial\u2010cephalic AVF (RCAVF) creation in a large cohort over 3\u00a0years.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>One hundred fifty RCAVFs were created between June 2018 and August 2021 with implantation of VasQ\u2122. Time to maturation, cannulation characteristics, and assisted (AP) and secondary patency (SP) rates were analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In this predominantly male (68%), median 64\u2009years old cohort, 150 VasQ\u2122 devices were implanted. Physiological maturation was achieved in 142\/150 (95%) and was unassisted in 133\/150 (89%). Of those, 129 matured within 1\u00a0month and four additional AVFs within 165\u2009days. Eight AVFs achieved maturation following percutaneous transluminal angioplasty, and one required surgical patch angioplasty. The median time from creation to first successful cannulation in dialysis patients was 41\u2009days. AP at 6, 12, 18, 24, and 30\u2009months was 89%, 81%, 78%, 73%, and 73%, and SP was 94%, 87%, 86%, 84%, and 84%, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Consistent use of the VasQ\u2122 device in RCAVF creation demonstrates excellent AVF maturation and patency rates with very low frequency of assisted maturation and interventions for maintenance. The VasQ\u2122 device appears a suitable aid in increasing the creation of functional
