Background: AIOD (Aorto-Iliac Occlusive Disease) may affect any of the arteries from the distal aorta to the common femoral arteries. CERAB (Covered Endovascular Reconstruction of Aortic Bifurcation) is a minimally invasive method used to treat significant and/or recurring aortoiliac occlusive disease. Bare-Metal stents are both effective and safe for treating AIOD. Bare-Metal stents had a statistically substantial greater risk of primary patency in both the general cohort and more complicated TASC C/D lesions.
