Risk factors for repeated percutaneous transluminal angioplasty of hemodialysis vascular access after initial intervention.

Background/aims: Percutaneous transluminal angioplasty (PTA) is a significant intervention to deal with occlusion and stenosis of vascular access. The study aimed to explore the risk factors of repeated PTA (re-PTA) after the initial intervention in patients undergoing hemodialysis.
