Introduction: The efficacy of arteriovenous fistula (AVF) for hemodialysis (HD) in the elderly population is still a matter of concern. Our study aimed to assess the results of arteriovenous fistula performed at our institution in patients aged 65 years and older.Methods: All chronic kidney disease (CKD) patients, aged 65 years or older, who underwent the creation of an AVF between December, 2021 and January, 2023, were included in this retrospective study. Essential demographic data, such as age, gender, and any other existing medical conditions were documented. Details regarding the method of access and the specific location were documented. The study's objective was to determine the primary and Cumulative (secondary) patency rates as the endpoint. The study had a minimum follow-up time of 1 year.Results: Within the study period, 116 AVF surgeries were done. The mean age was 69.4 years. We created brachiocephalic AVF in 68% of cases (n=79), radiocephalic AVF in 21% (n=24), brachiobasilic Transposition in 5% (n=6), using brachiocephalic transposition in 2.58% (n=3), and with a PTFE graft in 1.7% (n=2). Additionally, two patients underwent a brachiobasilic (side-to-side) approach. The overall survival rate of the AVF was 74% at one year following formation. By the 18th month, the primary and secondary potencies were 58.6% and 69%. BC AVF has better survival rate compared to RC AVF and BBT. In terms of the reasons for access failure, thrombosis accounted for 50%, Non thrombotic complications in 16% and severe cannulation injury in 10%Conclusion: In elderly population our aim should be to create the initial access point that has the highest likelihood of maintaining dialysis over an extended period of time. We have found that Complications are the primary driver of AVF failure (coefficient 1.19, P-value<0.001), while AVF type alone does not significantly predict failure.
