Surgical Repair of Saccular Renal Artery Aneurysm

Renal artery aneurysm is a relatively uncommon condition that is usually detected incidentally after an imaging workup. A renal artery aneurysm is defined as a dilated segment of renal artery that exceeds twice the diameter of a normal renal artery. Symptomatic renal artery aneurysms can cause hypertension, pain, hematuria, and renal infarction. Asymptomatic renal artery aneurysms may seem benign, but the potential for rupture and fistulization increases with size. In this report we describe the treatment strategy of saccular renal artey aneurysm in a 47-year-old man who presented with flank pain.
