Abstract:Background: To address high rates of arteriovenous fistula (AVF) failure, a mesenchymal stem cell (MSC)-seeded polymeric perivascular wrap has been developed to reduce neointimal hyperplasia (NIH) and enhance AVF maturation in a rat model. However, the wrap's radiolucency makes its placement and integrity difficult to monitor. Purpose: In this study, we infused gold nanoparticles (AuNPs) into the polymeric perivascular wrap to improve its radiopacity and tested the effect of infusion on the previously reported… Show more
