Survival analysis was performed by Kaplan-Meier and COX multivariate regression analysis, The median survival time of 104 AVFs was 39.633 ± 8.477months. Hypertension as primary disease was concluded benificial factor, age was risk factor. All the factors were brought into competing risk model. Age was concluded as risk factor, peripheral vascular disease and EPO were beneficial factors.Conclusion1.The AVFs of the elderly become dysfunctional easier because of poor vascular condition.2.
