Vascular access problems lead to increased patient morbidity and mortality and place a large burden on care facilities, manpower and costs. Autogenous arteriovenous fistulas (AVF) are preferred over arteriovenous grafts (AVG) because of a lower incidence of vascular access related complications. An aggressive increase in the utilization of AVF, however, results in an increased incidence of AVF early failure and non-maturation. Increasing evidence suggests that routine preoperative assessment results in an increased utilization of functioning AVF by better selection of adequate vessels. To date, the reproducibility and standardization of assessment protocols are lacking and assessment of a single morphological parameter has not enabled adequate prediction of postoperative AVF function for individual patients. In this paper, we provide an overview of available diagnostic modalities and parameters that potentially enable better selection of adequate vessels for successful AVF creation.
血管通路问题会导致患者发病率和死亡率上升，并给护理机构、人力和成本带来巨大负担。由于血管通路相关并发症的发生率较低，自体动静脉内瘘（AVF）比动静脉移植物（AVG）更受青睐。然而，积极增加AVF的使用率会导致AVF早期失败和未成熟的发生率增加。越来越多的证据表明，常规术前评估通过更好地选择合适的血管，可提高功能性AVF的使用率。迄今为止，评估方案缺乏可重复性和标准化，对单一形态学参数的评估无法充分预测个体患者术后AVF的功能。在本文中，我们概述了可用的诊断方法和参数，这些方法和参数可能有助于更好地选择合适的血管，以成功创建AVF。
