BACKGROUND
A brachial artery aneurysm (BAA) is a rare condition accounting for 5% of all peripheral arterial aneurysms. More cases of true BAAs after arteriovenous fistula (AVF) closure have been reported in the past two decades.
CASE PRESENTATION
A 60-year-old man who underwent AVF closure after renal transplantation had a true BAA on his left elbow that had grown within the past 6 months. We successfully performed an open repair with end-to-end anastomosis. No complications occurred for 1 year.
CONCLUSIONS
High flow due to AVF and some collateral factors such as the use of steroids and immunosuppressants after renal transplantation, arteriosclerosis, and chronic mechanical stimulation might contribute to BAA formation.
背景
肱动脉动脉瘤（BAA）是一种罕见疾病，占所有周围动脉动脉瘤的5%。在过去二十年中，有更多关于动静脉瘘（AVF）闭合后真性BAA病例的报道。
病例介绍
一名60岁男性在肾移植后接受了AVF闭合术，其左肘部出现一个真性BAA，在过去6个月内有所增大。我们成功进行了端到端吻合的开放修复术。术后1年未出现并发症。
结论
AVF导致的高流量以及一些辅助因素，如肾移植后使用类固醇和免疫抑制剂、动脉硬化和慢性机械刺激，可能促使BAA形成。
