摘　　要：目的探讨高频彩超对尿毒症稳定血透患者动静脉内瘘(AVF)并发症评估的应用价值。方法对78例稳定血透患者桡动脉、头静脉及吻合口内径(D)、峰值流速(PSV)、阻力指数(RI)以及肱动脉流量进行监测并记录并发症情况。结果43.6%(34/78)产生并发症,其中38.2%(13/34)静脉瘤样扩张、32.4%(11/34)血栓形成、26.5%(9/34)盗血征象、2.9%(1/34)假性动脉例瘤,7.7%(6/78)出现狭窄。流量(1203±457)mI/min(225~2590 ml/min),低、高流量组并发症发生率为75.0%(15/20)、50.0%(9/18)与25.0%(10/40)中等流量组差异具有统计性,差异有统计学意义(P<0.05);狭窄组血流量较正常组有显著差异,差异有统计学意义(P<0.05)。结论稳定血透者也可发生并发症,通过常规高频彩超监测起到早发现早干预延长内瘘使用时间的作用。Objective To explore the application value of high frequency color ultrasound in the evaluation of complications of arteriovenous internal fistula(AVF)in patients with uremia with stable hemodialysis.Methods The radial artery,cephalic vein and anastomotic stoma diameter(D),peak velocity(PSV),resistance index(RI)and brachial artery flow were monitored and complications were recorded in 78 patients with stable hemodialysis.Results Complications occurred in 43.6%(34/78),including 38.2%(13/34)phlebotoma-like dilatation,32.4%(11/34)thrombosis,26.5%(9/34)signs of blood theft,2.9%(1/34)false arterial tumor,and 7.7%(6/78)stenosis.The incidence of complications in the low and high flow groups was 75.0%(15/20),50.0%(9/18)and 25.0%(10/40),respectively,with statistically significant difference(P<0.05)in the flow group(1203±457)mI/min(225-2590ml/min).The blood flow in the stenosis group was significantly different from that in the normal group(P<0.05).Conclusion Complications may also occur in stable hemodialysis patients,and conventional high-frequency color ultrasound monitoring plays an important role in early detection and early intervention to prolong the use time of internal fistula.
