Abstract：
BACKGROUND: Although renal artery aneurysms (RAAs) are rare and often asymptomatic with slow growth, their natural progression and optimal management are not well understood. Treatment recommendations for RAAs do exist; however, they are supported by limited data.
METHODS: A retrospective cohort study was conducted to explore the management of patients diagnosed with an RAA at our institution from January 1st, 2013, to December 31st, 2020. Patients were identified through a search of our radiological database, followed by a comprehensive chart review for further assessment. Data collection encompassed patient and aneurysm characteristics, the rationale for initial imaging, treatment, surveillance, and all-cause mortality.
RESULTS: One hundred eighty-five patients were diagnosed with or treated for RAAs at our center during this timeframe, with most aneurysms having been discovered incidentally. Average aneurysm size was 1.40 cm (±0.05). Of those treated, the mean size was 2.38 cm (±0.24). Among aneurysms larger than 3 cm in size, comprising 3.24% of the total cases, 83.3% underwent treatment procedures. Only 20% of women of childbearing age received treatment for their aneurysms. There was one instance of aneurysm rupture, with no associated mortality or significant morbidity.
CONCLUSIONS: Our institution\'s management of RAAs over the period of the study generally aligned with guidelines. One potential area of improvement is more proactive intervention for women of childbearing age.

摘要：
背景：尽管肾动脉动脉瘤（RAAs）很少见，并且通常无症状且生长缓慢，他们的自然进程和最佳管理还没有得到很好的理解。确实存在针对RAA的治疗建议；但是，它们由有限的数据支持。
方法：进行了一项回顾性队列研究，以探索从1月1日起在我们机构诊断为RAA的患者的管理。2013年12月31日,2020年。通过搜索我们的放射学数据库确定了患者，然后是全面的图表审查，以便进一步评估。数据收集包括患者和动脉瘤特征，初始成像的基本原理，治疗,监视,和全因死亡率。
结果：在此期间，我们中心有一百八十五名患者被诊断为RAA或接受RAA治疗，大多数动脉瘤都是偶然发现的。平均动脉瘤大小为1.40cm(±0.05)。在接受治疗的人中，平均大小为2.38cm(±0.24)。在大小大于3厘米的动脉瘤中，占总病例的3.24%，83.3%接受了治疗程序。只有20％的育龄妇女接受了动脉瘤治疗。有一次动脉瘤破裂，没有相关的死亡率或显著的发病率。
结论：我们机构在研究期间对RAAs的管理总体上与指南一致。一个潜在的改进领域是对育龄妇女进行更积极的干预。
