腎動脈血管瘤是一種不常見之疾病，大部份均無症狀，但部份病患則可能發生血尿、高血壓、疼痛、低容量性休克及婦女在懷孕時，會發生血管瘤破裂…等併發症。治療腎動脈血管瘤時，傳統均以手術治療為主，但現在血管內動脈栓塞術是另一種選擇方法。我們報告以血管內動脈栓塞術成功治療三例腎動脈血管瘤。

Renal artery aneurysm (RAA) is a rare disease. Most cases are silent, although some may produce symptoms such as hematuria (gross or microscopic), pain, hypovolemic shock, hypertension, and rupture of the RAA in pregnancy, RAA has traditionally been treated by open surgery.
