Abstract

Background: The purpose of this study was to determine the primary patency rate of endovascular interventions in hemodialysis patients who had central venous stenosis or occlusion. Material and Methods: Twenty-seven hemodialysis patients, who underwent endovascular intervention between January 2013 and January 2018 for central venous stenosis or total obstruction, were included in the study. Endovascular interventions consisted of percutaneous transluminal angioplasty (PTA) or stent implantation. Primary patency rate of endovascular intervention at the sixth and twelfth months were evaluated. Results: Stent implantation and PTA were used in 5 patients and 22 patients, respectively. 14 patients had stenosis and 13 patients had occlusion. The total procedural success rate was 81%, 86% in stenosis and 77% in occlusion. There was no procedure-related complication. The primary patency for PTA at 6 and 12 months were 40% and 10%, respectively. For stent implantation, primary patency rate at 6 and 12 months was 70% and 30%, respectively. Conclusion: Endovascular interventions for central venous stenosis and occlusion are safe, with low rates of technical failure and they can be first-line treatment for central venous stenosis or occlusion in hemodialysis patients.
