Abstract: The evaluating effect of color Doppler ultrasound(CDUS)in monitoring the changes of hemodynamic parameters before and after operation of autogenous arteriovenous fistula (AVF) is analyzed in this study. 94 patients with AVF were examined by CDUS. The PSV, EDV, RI, RAD, CVD, RVF and CVF at four time points were measured and compared:before operation, 2,4 and 8 weeks after operation. The results show that the means of PSV, EDV, RAD, CVD, RVF and CVF at 2,4 and 8 weeks after operation were significantly increased than those before operation (P<0.05). The mean of RI at 8 weeks later was significantly lower than that before operation (P<0.05). 81 cases of arteriovenous fistula were mature; the maturity was 86.17%. The PSV, EDV, RAD and RVF of mature group were significantly increased than those of immature group (P<0.05), while RI value was significantly lower than that of immature group (P<0.05). Therefore, CDUS can real-time monitor the dynamic changes of hemodynamic parameters and evaluate the maturity of AVF effectively.

Key words: autogenous arteriovenous fistula, color Doppler ultrasound, hemodynamic parameters
