Predictors of recurrent arteriovenous fistula stenosis in Saudi patients undergoing hemodialysis

Abstract

Objectives: To identify predictors of recurrent arteriovenous fistula (AVF) stenosis. It also seeks to calculate the average primary patency duration in Saudi patients undergoing hemodialysis. Original Articlehad >3 total stenotic events. Clinical, radiological, and laboratory variables were collected and subjected to multivariate binary regression analysis to assess the odds of a recurrence of fistula stenosis.Results: A total of 29 patients were categorized as cases, while 70 patients were categorized as controls. The median primary patency duration was found to be seven months. Multivariate binary regression analysis revealed higher levels of serum calcium (p=0.012) and BMI (p=0.007) in patients with recurrent stenosis. A positive association was also observed between the use of antiplatelets (0.039) and recurrent stenosis. Conclusion:Higher levels of corrected calcium, BMI, and the application of antiplatelet therapy were found to be predictors of recurrent AVF stenosis. No other traditional variables were found to be significant.
