Renal Artery Aneurysm and Arteriovenous Fistula Associated with Fibromuscular Dysplasia: Successful Treatment with Detachable Coils

Renal artery aneurysms are more common in patients with fibromuscular dysplasia (FMD). Although these aneurysms have traditionally been managed surgically, endovascular techniques are playing a larger role. Many treatment methods involve the use of stent-grafts to exclude the aneurysm or bare stents to protect the main renal artery while coil embolization is performed through the interstices. Herein, the authors present a patient with an arteriovenous fistula secondary to FMD that was managed entirely with use of detachable coils, which allowed preservation of the uninvolved renal parenchyma.
