Abstract

Renal vein aneurysms are a rare clinical entity but their association with a renal idiopathic arterio-venous fistula can be considered an exceptional event. We report the case of a 60-year-old female with an asymptomatic right renal vein aneurysm secondary to an idiopathic proximal intraparenchymal arteriovenous fistula. The patient underwent transcatheter embolization of the renal vein aneurysm with temporary distal renal vein balloon occlusion. Therapeutic options nowadays available and technical details of the procedure performed are analyzed.
