Abstract:
OBJECTIVE:To evaluate the service life of the arteriovenous fistula (AVF) in patients with dialysis and to explore the associated factors for AVF service life.
METHODS:A cohort study regarding 472 cases with AVFs at the Second Xiangya Hospital from January 2009 to December 2009 was retrospectively analyzed. The AVF placement-associated primary and secondary failure rates, complications and various risk factors were examined. Kaplan-Meier survival curves and Cox proportional hazard models were used to determine the service life and associated factors.
RESULTS:By the end of January 1st, 2014, after excluding the patients with indeterminate outcome (72 lost to follow-up; 101 died; 44 transplanted), the primary failure rate was 10.9%, the survival rate for 1, 3 or 5 years was 80.5%, 65.1% or 50.5%. The complication rate and hospitalization rate for AVF were 39.8% and 9.8%, respectively. The influential factors for AVF were diastolic hypotension (HR: 0.86; 95% CI: 0.82 to 0.89), diabetes (HR: 1.87; 95% CI: 1.32 to 3.31) and serum albumin (HR: 0.83; 95% CI: 0.74 to 0.94).
CONCLUSION:The complications after AVF placement must be considered before the surgery schedule. Hypotension, diabetes and serum albumin are the main risk factors for AVF service life.
