The aortoiliac occlusive disease triggers critical limb ischemia; however, the blood supply of lower extremities can be sustained through possible collateral channels. Due to the development of collateral circulation, a substantial number of patients with aortoiliac occlusion remain clinically silent and asymptomatic. Internal mammarian artery originates from the same embryogenic dorsal aorta with inferior epigastric artery and serves as a possible collateral supply in aortoiliac occlusive disease. The connection between the internal mammarian artery and the inferior epigastric artery is known as Winslow’s pathway. Harvesting of internal mammarian artery in coronary artery bypass grafting surgery can result in critical limb ischemia in aortoiliac occlusive disease with patent Winslow’s pathway.
Key Words: Aortoiliac occlusive disease, internal mammarian artery, Winslow’s pathway
