Relationship between bovine carotid artery grafts for hemodialysis access and human leukocyte antigen sensitization

Abstract

Bovine carotid artery (BCA) Artegraft is a biologic graft that can be utilized as a conduit for permanent hemodialysis access and has been shown to outperform polytetrafluoroethylene grafts. However, concern regarding immunologic sensitization may limit the use of BCA in the transplant candidate. Panel reactive antibody (PRA) is an immunological test utilized in transplant recipient selection whereas increases in PRA limit access to transplantation. The purpose of our study was to determine whether BCA graft placement was adversely associated with increases in PRA.
