血液透析进入循环的最佳途径是天然和合成动静脉瘘（AVF和AVG）。静脉流出性狭窄引起的血栓阻止了房室通路的长期使用。本初步研究旨在评估超声稀释衍生通路血流检测房室通道狭窄的能力，并评估其对治疗的反应。本初步研究为单中心前瞻性观察性干预试验。使用的监测技术是每月和在任何干预后进行的超声稀释访问血流量测量。干预措施的筛选标准是，当流量值低于1000 mL/min或绝对流量低于1000 mL/min时，通道流量减少20%
Background Hemodialysis access to the circulation is best provided by native and synthetic arteriovenous fistulae (AVF and AVG). Thromboses caused by venous outflow stenoses pre vent the long-term use of AV access. This pilot study was performed to evaluate the ability of ultrasound dilution-derived access blood flows to detect AV access stenosis and to evaluate the response to treatment.Methods. This pilot study was a single-center, prospective observational intervention trial. The monitoring technique used was ultrasound dilution access blood flow measurements performed monthly and after any intervention. Screening criteria for interventions were decrements in access flow of 20% when the flow value fell under 1000 mL/min or absolute flow of
