SANCHEZ GONZALEZ, Juan Carlos. Risk factors associated with a fistula arteriovenous dysfunction in patients with chronic kidney disease. Enferm Nefrol [online]. 2013, vol.16, n.2, pp.104-114. ISSN 2255-3517.  https://dx.doi.org/10.4321/S2254-28842013000200007.

Renal disease has become a chronic disease of high prevalence in industrialized countries. A form of renal replacement therapy is hemodialysis, which is essential to have a vascular access. As vascular access of choice preferable to central venous catheter is arteriovenous fistula for showing fewer complications. However, it is not without risks and problems as related to vascular access are the leading cause of morbidity and hospitalization, we intended to study the risk factors that influencing arteriovenous fistulas dysfunction. Methods: This is a case-control design in which we compared the group with some fistula dysfunction, either autologous or prosthetic, with which presented no dysfunction to analyze the differences between both. The variables were grouped into three sections defined to organize the results and stratified by gender, age and having suffered or not fistula dysfunction. Results: Age and gender do not influence fistula dysfunction but has more influence dyslipidemia, having started hemodialysis, type of fistula and have carried central venous catheter. Discussion: Unlike studies published, in our population did not find fistula dysfunction differences in age and gender. However, it is seen that there is less risk of dysfunction in patients with dyslipidemia, wherein the fistula is autologous and the hemodialysis have not started or have done on a scheduled start and, therefore, they have not carried central venous catheters.
