We evaluated the importance of vascular access in hemodialysis patients using noninvasive methods with the Transonic Systems monitor in 108 patients. Most of these patients (84%) had native vein fistulas. We found that a blood flow rate of below 500 ml/min suggested the occurrence of vascular stenosis and justified confirmation by angiography. Increased recirculation could be evaluated readily and was detected in only 10% of patients. Finally, employing the evaluation of the Kt/V index, we found a good correlation between low flux through the fistula and a low Kt/V value.
我们使用Transonic系统监测仪，通过非侵入性方法对108例血液透析患者的血管通路重要性进行了评估。这些患者中的大多数（84%）有自体动静脉内瘘。我们发现，血流速率低于500毫升/分钟提示血管狭窄的发生，有必要通过血管造影进行确认。再循环增加可以很容易地评估出来，且仅在10%的患者中检测到。最后，通过评估Kt/V指数，我们发现内瘘低血流量与低Kt/V值之间存在良好的相关性。
