Digital model of radiocephalic arteriovenous fistula for decision support and improvement of maturation

The native arteriovenous fistula (AVF) is the recommended first intention vascular access in dialysis patients. This non-physiological surgical construction implies many anatomical and hemodynamic parameters. Radio-cephalic AVFs are preferred due to a low rate of long-term complications. The early rates of thrombosis and failure of maturation of the distal AVFs remain high, between 20 and 50%. The aim of this work was to obtain a faithful digital model simulating the flow of a radiocephalic AVF to guide the surgeon in the choice and the technical realization of AFVs in order to improve maturation.
