Introduction: Nowadays, many patients owe their lives for dialysis. The first
step is to find suitable vessels so in acute cases, a catheter to is placed in central
venous system and is chronic cases an arteriovenous fistula or an artificial graft is
The purpose of this study is evaluation of A-V fistula survival and variety of
complications in order to prevent or at least decrease the complications, and also
this helps the fistula not to be disabled.
Methods: This study was a historical cohort type. Our statistical population was
composed of 150 patients that referred to Shahid Rahnemoun hospital’s
hemodialysis center for hemodialysis and A-V fistula surgery. The sampling
method used was census. To determine one-year, four–year and ten–year
survival, Kaplan-Meier-Logrank test were used.
Results: There isn’t any significant difference between age and sex groups. Mean
fistula preservation in the diabetic and poly cystic kidney, pyelonephritis,
glumeronphritis patients doesn’t have significant difference from others. Other
results about aneurism and infection are the same. 6 cases of 110 patients have
thrombosis and in 5 cases, their fistula was inactive. There is a significant
difference between mean fistula preservation of theses patients and the others
Conclusion: According to result of this study, thrombosis was the main and the
most prevalent factor for A-V fistula’s inactivation. Fistula infection is a
complication that responds to treatment well.
