CLI (Rutherford class IV-VI) is a terminal stage of peripheral artery disease (PAD); it is defined by the presence of resting pain and/or tissue loss for at least two weeks that may require urgent revascularization to promote healing and prevent limb loss.For patients with infrarenal aortoiliac occlusive disease, the revascularization options are surgery like aortofemoral bypass and axillofemoral bypass or percutaneous intervention. Aortoiliac and aortofemoral bypass procedures are associated with 74% to 95% 5-year patency rates, respectively, which are comparable but not superior to percutaneous therapies.These operations may imply a significant morbidity and mortality on CLI patients who usually have multiple comorbid conditions and are considered high risk patients.
