摘要: 本研究探讨了彩色多普勒超声(CDUS)监测自体动静脉内瘘(AVF)手术前后血流动力学参数变化以评估AVF成熟度的效果。选取首次行AVF手术的患者94例,分别于手术前、术后2周、4周、8周行CDUS检查,测量并比较桡动脉收缩期峰值流速(PSV)、舒张期峰值流速(EDV)、阻力指数(RI)及桡动脉内径(RAD)、头静脉内径(CVD)、桡动脉血流量(RVF)、头静脉血流量(CVF)。结果显示,术后2周、4周、8周,患者PSV、EDV、RAD、CVD、RVF、CVF均值较术前明显增加(P<0.05)。术后8周,患者RI均值较术前明显降低(P<0.05)。动静脉内瘘成熟81例,成熟度86.17%;成熟组PSV、EDV、RAD、RVF较未成熟组均明显增加,RI值较未成熟组明显降低(P<0.05)。本文结果表明CDUS可对AVF术后血流动力学的动态变化进行实时监测,有效评估AVF成熟程度。

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.
