Endovascular management of isolated iliac artery aneurysms.

Isolated iliac artery aneuryms are detected increasingly as a result of expanding use of diagnostic imaging, and screening programmes. This present review describes endovascular solutions for the management of isolated iliac artery aneurysms. This was a review of the published literature on endovascular treatment of iliac aneurysms. Most of the papers were case series, and there are no randomized studies. Aneurysms of the common iliac artery are most common, followed by internal, then external iliac aneurysms. Indications for intervention remain unclear, but are generally based on diameter. Endovascular solutions exist for at least half the aneurysms that required treatment, including as an emergency. Often a standard bifurcated solution, as for abdominal aortic aneurysm is indicated, however, there are a number of other novel solutions to deal with variable anatomy. Endovascular treatment of iliac aneurysms is less painful and reduces hospital stay. However, outcome data remain limited, and formal comparison with open surgery is awaited.
