Abstract: 【Abstract】Hemodialysis is the main renal replacement therapy for patients with end-stage renal disease. Complications of long-term arteriovenous access are the main reason for hospitalization in hemodialysis patients. Percutaneous interventional therapy can be used in poor function or failure of the arteriovenous access due to vein or arterial stenosis, which has the advantages of few trauma and blood loss and retention of limited blood vessel resources. Percutaneous transluminal angioplasty is the initial standard treatment for most dialysis pathway lesions. Percutaneous transluminal stenting has the advantages in dealing with central venous stenosis. Early intervention on malfunctional arteriovenous access is essential for extending the service life of arteriovenous access and improving patients’quality of life.

Key words: Arteriovenous access, Percutaneous transluminal angioplasty (PTA), Percutaneous transluminal stenting
