ABSTRACT

Background. Hemodialysis is the most utilized treatment for chronic renal failure worldwide and vascular access remains as the cornerstone for its treatment.
Objective. To evaluate the behavior of arteriovenous hemodialysis fistulae.
Material and methods. A descriptive, retrospective and cross-sectional study, analyzing: age, gender, risk factors, etiology of chronic renal disease, number of previously placed central venous catheters, types fistulae and complications. The data found were analyzed using SPSS 20 program.
Results. There were 60 fistulas performed in 50 patients, finding: age of 57.41 ± 19.3; sex: female, 20 (33.3%); male, 40 (66.7%). The etiology of chronic renal failure: diabetes mellitus 40 (63.3%), renal hypoplasia 9 (15%) and glomerulonephritis 6 (10%). 100% had a history of previously placed central venous catheter; 47 (78.3%) of native fistulas, 13 (21.7%) of synthetic, 38 (63.3%) of brachiocephalic type and 9 (15%) Brescia-Cimino. fiveteen (25%) presented complications. Statistic significance fiveteen (p ≤ 0.05) with χ² was found in the association of risk factors such as diabetes mellitus, systemic arterial hypertension and the presence of previous central venous catheter with vascular access failure.
Conclusions. The placement of brachiocephalic fistulae had a complication percent higher than that reported in the literature. For this reason it is considered necessary to refer to the vascular surgeon as soon as possible not only to plan the first access, but also to investigate it’s handling in the hemodialysis unit and to foresee other placement sites in the future.
