Abstract:
Autogenous arteriovenous fistula (AVF), compared to other vascular access routes, offers the advantages of stable blood flow, fewer complications, and a longer service life, making it the primary type of vascular access and the first choice for hemodialysis patients. The failure rate of AVF maturation is as high as 20% to 60%, primarily due to intimal hyperplasia following AVF surgery. Currently, the origin, function, and differentiation status of neointimal cells are not well understood, and most knowledge about neointimal cells was inferred from arterial neointima in non-AVF systems. Understanding the source of neointimal cells in AVF is crucial for experimental design and effectively providing strategies to reduce intimal hyperplasia. This article reviews the situation of venous intimal hyperplasia in patients with stage 5 chronic kidney disease, the relationship between changes in venous vessel wall and neointimal cells after AVF surgery, and the effects of outer membrane fibroblasts, local smooth muscle cells, and circulating bone marrow progenitor cells on AVF intimal hyperplasia. It is hoped that this will provide a reference for the treatment of intimal hyperplasia and experimental research.
