Abstract:

OBJECTIVE: Life expectancy and quality of life in hemodialysis patients are directly proportional to the effective use of the vascular access way. Complications in arteriovenous fistulas are related to morbidity. The aim of this study was to evaluate the incidence of early and long-term patency of arteriovenous fistulas (AVF) and the results of surgical treatment of patients with chronic kidney failure. MATERIAL AND METHODS: We retrospectively evaluated 152 AVFs used for vascular access from their non-dominant upper extremities for hemodialysis in 121 patients between January 2019 and January 2020. RESULTS: There were 68 (44,7%) cimino-brescia, 62 (40,7%) brachiocephalic, and 22 (14,4%) brachiobasilic AVFs. Complication in acute stage was found in 18 AVFs (11,8%) and late stage immatureness and the development of complication was found in 11 AVFs (/,1%). Acute complications of distal fistula were found 21%, acute complications of proximal fistula were found 12% and detected as statistically significantly higher (p<0.05). In the late period, there was no statistical difference between the failure rates of AVFs opened proximally and AVFs opened distally (p>0.05). Complications were detected in 29 (18.8%) of AVFs that were opened. CONCLUSIONS: The success rate of AVFs formed in the distal of the extremity was found to be lower than those opened in proximal localizations. However, in order to protect the brachial region by using it in the future, AVF applications opened primarily to the distal regions should be the first choice.
