Abstract :

Vascular access graft failure and infection are major complications in hemodialysis patients. This experimental study tested new biomaterial-coated grafts designed to resist thrombosis and bacterial colonization in a sheep model over 6 months. The coated grafts demonstrated significantly improved patency rates (90% vs. 65%) and reduced bacterial biofilm formation compared to standard PTFE grafts. Histological analysis revealed decreased inflammatory cell infiltration. These findings suggest biomaterial innovation may enhance long-term vascular access outcomes.
