Bilateral Renal Artery Aneurysms: about a Case

Abstract

A renal artery aneurysm is defined as a dilated segment of the renal artery that exceeds twice the diameter of a normal renal artery. Although rare, the diagnosis and incidence of this entity has steadily increased with the routine use of cross-sectional imaging. In some cases, renal artery aneurysms can be clinically telling and potentially lethal. However, knowledge about their occurrence, natural history and prognosis with or without treatment is still limited. The purpose of this article is to review the recent literature concerning renal artery aneurysms, with particular attention to pathophysiology, aspect of imaging, indications for treatment, different technical options, post-procedural complications and treatment outcomes.
