PurposeTo identify the spectrum of clinical presentation of iliac artery fibromuscular dysplasia (FMD) and to evaluate the outcomes of endovascular management of iliac artery FMD for claudication.Materials And MethodsAll patients in a single institution with a diagnosis of FMD between January 1980 and December 2010 were identified. Iliac artery FMD was present in 14 patients. Associated risk factors included hypertension (79%), hyperlipidemia (64%), smoking history (36%), coronary artery disease (21%), diabetes (0%), and obesity (36%).ResultsIn eight (57%) patients, iliac artery FMD was incidentally found on imaging. Lifestyle-limiting claudication involving one or both extremities was present in six (43%) patients. All six patients were reported to have mild peripheral arterial disease based on ankle-brachial index measurements (0.7-0.9). These six patients underwent 10 endovascular procedures for claudication, including angioplasty (n = 8) and self-expanding stent placement (n = 2). Mean symptom-free survival was 56.3 months.ConclusionsIliac artery FMD that is amenable to endovascular treatment may be found incidentally or may manifest with disabling claudication.Copyright © 2014 SIR.
