3. We recommend endovascular procedures over open surgery for focal AIOD causing IC (Grade 1, Level B).
4. We recommend endovascular interventions as first-line revascularization therapy for most patients with common iliac artery or external iliac artery occlusive disease causing IC (Grade 1, Level B).
5. We recommend the selective use of BMS or covered stents for aortoiliac angioplasty for common iliac artery or external iliac artery occlusive disease, or both, due to improved technical success and patency (Grade 1, Level B).
6. We recommend the use of covered stents for treatment of AIOD in the presence of severe calcification or aneurysmal changes where the risk of rupture may be increased after unprotected dilation (Grade 1, Level C).
7. For patients with diffuse AIOD (eg, extensive aortic disease, disease involving both common and external iliac arteries) undergoing revascularization, we suggest either endovascular or surgical intervention as first-line approaches. Endovascular interventions that may impair the potential for subsequent AFB in surgical candidates should be avoided (Grade 2, Level B).
8. EVT of AIOD in the presence of aneurysmal disease should be undertaken cautiously. We recommend that the modality used should either achieve concomitant aneurysm exclusion or should not jeopardize the conduct of any future open or endovascular aneurysm repair (Grade 1, Level C).
9. In all patients undergoing revascularization for AIOD, we recommend assessing the CFA. If hemodynamically significant CFA disease is present, we recommend surgical therapy (endarterectomy) as first-line treatment (Grade 1, Level B).
10. In patients with iliac artery disease and involvement of the CFA, we recommend hybrid procedures combining femoral endarterectomy with iliac inflow correction (Grade 1, Level B).
11. We recommend direct surgical reconstruction (bypass, endarterectomy) in patients with reasonable surgical risk and diffuse AIOD not amenable to an endovascular approach, after one or more failed attempts at EVT, or in patients with combined occlusive and aneurysmal disease (Grade 1, Level B).
12. In younger patients (age <50 years) with IC, we recommend a shared decision-making approach to engage patients and inform them of the possibility of inferior outcomes with either endovascular or surgical interventions (Grade 2, Level C).
13. We recommend either axial imaging (eg, CT, MR) or catheter-based angiography for evaluation and planning of surgical revascularization for AIOD (Grade 1, Level Ungraded).
14. When performing surgical bypass for aortoiliac disease, concomitant aneurysmal disease of the aorta or iliac arteries should be treated as appropriate (exclusion) and is a contraindication to end-to-side proximal anastomoses (Grade 1, Level Ungraded).
15. For any bypass graft originating from the CFA, the donor iliac artery must be free of hemodynamically significant disease or any pre-existing disease should be corrected before performing the bypass graft (Grade 1, Level Ungraded).
