Abstract: Nowadays maintenance hemodialysis (MHD) uses the vascular access of autologous arteriovenous fistula (AVF), graft arteriovenous fistula (AVG) or central venous catheter (CVC), in which AVF is the preferred vascular access route recommended by various guidelines and is also the main method for MHD patients in China. Well-functioning vascular access is essential to hemodialysis, while adverse events in AVF including late maturation, stenosis, occlusion and thrombosis often disturb the hemodialysis. Thrombosis in AVF directly leads to lower hemodialysis efficiency or even completely interrupts the hemodialysis. Here we summarize the mechanism and influencing factors of thrombosis in AVF in order to prevent this event from happening.

Key words: Maintenance hemodialysis, Autogenous arteriovenous fistula, Thrombosis, Stenosis
