Abstract: Objective This study aims to evaluate the safety and efficacy of percutaneous innominate vein catheterization for long-term hemodialysis vascular access. Method End-stage renal disease patients requiring long-term central venous access, suitable for innominate vein catheterization and treated in our hospital from Jan. 2014 to Jan. 2016 were enrolled in this study. Clinical history and preoperative examinations were carefully evaluated. Innominate vein catheterization was performed under X-ray fluoroscopy. Procedurerelated complications were recorded, and the patency of hemodialysis access was followed up. Results A total of 19 patients (4 male, 21.1%) were included in this study, with an average age of 63.6±8.4 yr and a median dialysis time of 30 (10, 84) months. All patients were successfully operated, and the catheters functioned well immediately after catheterization. After discharge, the patients were followed up for a median of 12 (6,20) months. All patients survived except one patient who died of upper gastrointestinal bleeding. No procedure- related major complication occurred. Three patients (15.8%) were hospitalized for access dysfunction, and the catheter function recovered after proper manipulation. The 12-month primary patency of accesses was 84.2%, and the secondary patency reached 100%. Conclusion Percutaneous innominate vein catheterization established under fluoroscopy guidance is safe and efficient for long-term hemodialysis access
