Background: The aim of this study is to analysis the effectiveness with patency rate of percutaneous bare metal stent for central venous stenosis/occlusion in patients who are undergoing hemodialysis. Methods: Totally 1016 central venous interventional procedures were performed in 891 patients during recent 10-year period. Four hundred and twenty-five subclavian (occlusion: 97, stenosis: 328) and 591 innominate (occlusion: 156, stenosis: 435) venous steno-occlusions were enrolled in this study. The follow-up period was 2 weeks–77 months (mean: 14.8 months). Technical success, complications, and long-term patency were evaluated as well as the statistic difference between the location of steno-occlusions, the existence of diabetes mellitus, and the history of central catheter. Results: Stents were implanted in 294 patients in 1016 procedures. All but one of the procedures was technically successful (99.7%). The one patient with an unsuccessful procedure was due to incomplete stent expansion. Two stent migrations were occurred as major complication without other. The primary patency rate for 6, 12, 24, and 36 months was 44%, 18%, 5%, and 2%, respectively (mean: 7.9 months). Repeat interventions, including additional balloon angioplasty and stent placement, were required in 172 patients (average: 2.54). There was no statistic difference except the history of central catheter (P = 0.0128). The secondary patency rate for 6, 12, 24, 36, 48, and 60 months was 80%, 67%, 42%, 37%, 30%, and 20%, respectively. Conclusion: Percutaneous central venous stent implantation in hemodialysis patients is useful in patients with suboptimal angioplasty and it was safe and effective to restore the hemodialysis function. However, repeat interventions are usually required to prolong the stent patency.
