Renal artery aneurysm is a rare condition that has an unclear etiology. Although some patients present with symptoms of hypertension, pain, hematuria, or rupture, the majority are asymptomatic. Traditional surgical repair of renal artery aneurysms is often complex and may require ex vivo repair and reimplantation of the kidney if branch vessels are involved. Very large aneurysms made require nephrectomy. More recently, reports have described endovascular approaches to renal artery aneurysms, including coil embolization and stent graft coverage. This report describes successful endovascular treatment of a 10-cm renal artery aneurysm with preservation of renal mass.

Key Words: renal artery • aneurysm • embolization
