Aneurisma de arteria renal: revisión de la literatura y reporte de caso

Abstract

Background: Renal artery aneurysm (RAA) is a rare vascular abnormality, the second in frequency of visceral aneurysms, it occurs in 0.09% of the general population, the age of presentation is 50 years, predominance in sex female, more frequent on the right side. The most common location is parenchymal saccular type. The annual growth rate is 0.06-0.6mm per year. Although they are asymptomatic, 70% are associated with arterial hypertension as the first manifestation. The factors that predispose to rupture are considered an absolute indication for conventional or endovascular surgical management. Endo-vascular management has shown a constant evolution, being a viable alternative with low morbidity and mortality. Embolization with liquid or metallic material or exclusion with a stent are options with proven effectiveness, however, they depend on the availability of each hospital center. Objective: We present a case of a hypertensive patient with the incidental diagnosis of an aneurysm of the right renal artery. Result: endovascular route was resolved due to rupture criteria, presents good postoperative evolution, renal ultrasound follow-up without evidence of aneurysm flow.
