Renal artery aneurysms (RAAs) represent a rare disease and are most commonly discovered as an incidental imaging finding. RAA may be associated with hypertension and are usually asymptomatic at presentation but may result in rupture, hematuria, or renal infarction. The natural history of RAA is poorly understood. Although there is general consensus that RAA that are symptomatic or identified in women at risk for pregnancy should be repaired, diameter criteria for repair of asymptomatic RAA are controversial and emerging evidence suggests that rupture incidence is low for those <2.5 cm in diameter. Options for repair of RAA have expanded over the preceding decades with expansion of both open surgical and endovascular treatments.
肾动脉动脉瘤（RAAs）是一种罕见疾病，最常作为偶然的影像学发现被检测出来。肾动脉动脉瘤可能与高血压有关，通常在发病时无症状，但可能导致破裂、血尿或肾梗死。人们对肾动脉动脉瘤的自然病程了解甚少。尽管普遍认为有症状的或在有妊娠风险的女性中发现的肾动脉动脉瘤应进行修复，但无症状肾动脉动脉瘤修复的直径标准存在争议，新出现的证据表明，直径小于2.5厘米的肾动脉动脉瘤破裂发生率较低。在过去几十年中，随着开放手术和血管内治疗的发展，肾动脉动脉瘤的修复选择有所增加。
