The vascular lab (VL) provides vital information for dialysis access to guide management. This article discusses the indication, protocol, and diagnostic criteria for the evaluation of arteriovenous fistulas and grafts. An arteriovenous (AV) dialysis access is made by creating a connection between an artery and vein (AV fistula [AVF]) or by interposing a conduit between an artery and a vein (AV graft [AVG]) to provide high flow circuit for hemodialysis. A normal mature AV dialysis access has a thrill or vibration from turbulent flow in the graft or vein. The nomenclatures at our institution for an AVF and AVG are in the Figure 1 A and B diagrams.
血管实验室（VL）为透析通路提供重要信息，以指导管理。本文讨论了评估动静脉瘘和移植物的适应证、方案和诊断标准。动静脉（AV）透析通路是通过在动脉和静脉之间建立连接（动静脉瘘[AVF]）或在动脉和静脉之间插入导管（动静脉移植物[AVG]）来形成的，以提供用于血液透析的高流量回路。正常成熟的 AV 透析通路在移植物或静脉中有湍流引起的震动或振动。我们机构对 AVF 和 AVG 的命名如图 1A 和 B 所示。
