Utilization of a Tubularized CorMatrix Extracellular Matrix for Repair of an Arteriovenous Fistula Aneurysm

Salvage of failing autogenous arteriovenous fistula (AVF) access sites is a primary concern in dialysis access preservation and a key emphasis of the Kidney Disease Outcomes Quality Initiative. Aneurysmal degeneration of autogenenous fistulae represents a significant complication, associated with potential skin breakdown, rupture, infection, and access loss. The utilization of conduits derived from extracellular matrix (ECM), currently approved for cardiovascular repairs, may mitigate some of the risks associated with salvage using synthetic materials. We report the utilization of a tubularized CorMatrix® ECM graft as a novel conduit for repair of a brachiocephalic AVF aneurysm.
