Symptomatic Renal Artery Aneurysm Dealt with Aneurysmectomy and Patch Closure

Abstract

Renal artery aneurysm (RAA) is a rare disease, and the precise incidence has not been very well known. It appears that with the increasing use of diagnostic ultrasound, computed tomography and arteriography, RAA are being identified more frequently than in the past. Rupture of RAA is associated with 10% mortality and the chance of nephrectomy is very high. Although, most of renal artery aneurysms are treated by endovascular technique, surgery is often necessary for aneurysms associated with bifurcation area or large braches. Here, we report a case of saccular renal artery aneurysm which was managed by open surgery.
