Abstract

The terminal abdominal aorta divides into the common iliac arteries at the L4 level. At the level of the sacrum, the common iliac arteries divide into the external iliac arteries and internal iliac (hypogastric) arteries. This review covers aneurysms of the iliac arteries, with discussion of the anatomy, clinical evaluation, investigative studies, management, and follow-up imaging. Figures show common presenting configurations of iliac artery aneurysms, examples of open repair techniques for common iliac artery aneurysms, example of internal iliac artery revascularization in the setting of common iliac artery aneurysm repair, examples of endovascular repair techniques for common iliac artery aneurysms, complex hybrid repair of multiple iliac aneurysms, examples of open repair techniques for internal iliac artery aneurysms, and examples of endovascular repair for internal iliac artery aneurysms. Tables list normal diameters reported by the Subcommittee on Reporting Standards for Arterial Aneurysms, rate of growth of aneurysms based on size at presentation, presenting signs and symptoms of iliac artery aneurysm, and location, rupture, and mortality reported in the literature. This review contains 7 highly rendered figures, 4 tables, and 91 references Keywords: Iliac artery aneurysms; IAA; Common iliac artery aneurysms; Internal iliac artery aneurysm; IIAA; External iliac artery aneurysm
