The common mechanism for low access flow is intimal hyperplasia leading to stenosis within the access circuit. Balloon angioplasty (percutaneous transluminal angioplasty, PTA) remains the mainstay of treatment despite multiple technologies introduced in the past. New technologies continue to be introduced in an effort to improve on outcomes of angioplasty. This article briefly reviews the use of and outcomes of PTA, technologies, past, present and future as well as some of the questions that remain unanswered with PTA.
低血流量的常见机制是内膜增生导致动静脉内瘘通路狭窄。尽管过去已引入多种技术，但球囊血管成形术（经皮腔内血管成形术，PTA）仍然是主要的治疗方法。为了改善血管成形术的效果，新技术仍在不断推出。本文简要回顾了PTA的应用情况和治疗效果、过去、现在和未来的技术，以及一些PTA仍未解决的问题。
