Arteriovenous fistula (AVF) is currently the hemodialysis access with the longest life expectations for the patients. However, even the AVF is at risk for many complications, especially the development of stenosis. The latter can not only lead to inadequate hemodialysis but also lead to AVF thrombosis. Duplex Doppler ultrasonography is a very precise method, in the hands of experienced professionals, for the diagnosis of AVF complications. In this review, we summarize the ultrasound diagnostic criteria of significant stenoses and their indication for procedural therapy.
动静脉内瘘（AVF）目前是患者预期使用寿命最长的血液透析通路。然而，即使是动静脉内瘘也存在许多并发症的风险，尤其是狭窄的发生。后者不仅会导致血液透析不充分，还会导致动静脉内瘘血栓形成。在经验丰富的专业人员手中，双功多普勒超声检查是诊断动静脉内瘘并发症的一种非常精确的方法。在这篇综述中，我们总结了显著狭窄的超声诊断标准及其介入治疗指征。
