Aneurysms of the external iliac artery are extremely rare. We present a case of a middle-aged male patient with calf claudication owing to peripheral arterial embolism on the basis of a thrombosed true aneurysm of the external iliac artery caused by cystic media necrosis. Vascular imaging established the diagnosis and we proceeded to removal of the aneurysm via open repair, with excellent surgical and clinical results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
