Outcomes and predictors of failure of arteriovenous fistulae for hemodialysis.

Arteriovenous fistula(AVF) is preferred vascular access for hemodialysis but has primary failure in 20–60%. Studying predictors of AVF failure would help plan appropriate management.We studied AVF outcomes, clinical and vascular factors predicting their failure in patients requiring hemodialysis. Retrospective study of patients with AVF creation from January 2017 to December 2018. Outcomes studied were immediate (  4.0 mm had less failures [immediate (p 0.01), primary (p 0.02)],   4.0 mm had less, < 2.0 mm had more failures.
