Objective: To evaluate long-term results in patients with haemodialysis (HD) access where percutaneous treatment of stenotic occluded central veins was performed. Material and methods: Authors followed-up retrospectively a group of 39 patients where successful percutaneous transluminal angioplasty (PTA) / stent implantation was performed. Results: Technical success was achieved in 85 % of the procedures, in 15 % authors did not succeed (always in occlusions). The primary 6-month patency rate was 58 %, the secondary patency rate was 92 %. To obtain these results authors had to perform 1.8 procedures per patient. Conclusion: Successful percutaneous intervention including possible reintervention usually helps to maintain long-term patency of fistulas.
