Introduction

Vascular access is one of the most important issues affecting the quality of life of patients who are dialysis-dependent.

Aim

The aim of our study was to determine the infection rates of permanent catheters. We also evaluated the thrombosis, maturation time, and patency rates of arteriovenous fistulas based on their location in the arm in dialysis patients.

Material and methods

The study included a total of 109 arteriovenous fistulas and 9 permanent catheters of 75 dialysis-dependent chronic kidney disease (CKD) patients from 3 different dialysis centers; 66 of the fistulas were patent and 43 were thrombosed. Arteriovenous fistulas were examined in three groups according to their location in the forearm: distal radiocephalic, proximal radiocephalic, and brachial region.

Results

66.7% of the participants had used at least one permanent tunneled catheter in their lifetime. Of those who had used at least one permanent catheter (n = 50), 6% experienced a permanent catheter infection. Among the patients, 41.3% had a thrombosed distal radiocephalic fistula, 2.7% had a thrombosed proximal radiocephalic fistula, and 8.0% had a thrombosed brachial fistula. Those under the age of 65 had shorter maturation times compared to those over the age of 65 (p < 0.05).

Conclusions

The most frequently used dialysis access was brachial region arteriovenous fistulas at 38.7%. There was no significant difference in maturation times between distal, proximal, and brachial region arteriovenous fistulas. Age above 65 negatively affects both fistula maturation and primary patency. The rate of permanent catheter infection among patients who had used at least one permanent catheter in their lifetime was found to be 4%.
