Abstract
Background: The patency of arteriovenous access is important for stable and effective hemodialysis, and long-term technical survival is best achieved with a native arteriovenous .stula (AVF). However, maintaining AVF patency remains a challenge. This study was designed to determine the independent prognostic factors for AVF patency according to hemodialysis duration. Methods: The primary study end point was unassisted patency of the AVF, which was de.ned as the time from the .rst .stula surgery to the .rst AVF failure. AVF failure was de.ned as an event that required percutaneous intervention or surgery to revise or replace the .stula, which occurred at least 2 months after .stula formation. Results: We enrolled 478 patients with a mean age of 55.5714.0 years, and mean duration of dialysis was 2.572.1 years. There were 109 cases (22.8%) of AVF failure. The factors related to AVF patency differed according to hemodialysis duration. Using a Coxadjusted model, we observed a signi.cant correlation between the incidence of AVF failure and diabetes within the initial 12 months of hemodialysis. Uncontrolled hyperphosphatemia (mean serum phosphorus45.5 mg/dL during hemodialysis) was associated with patency loss of AVF after 1 year of hemodialysis. Conclusion: Various factors were associated with the development of patency loss of AVF as hemodialysis duration differed, and a preventive role of hyperphosphatemia control in AVF survival needs further clinical study.
