Isolated aneurysm of the bilateral iliac arteries is rare, and frequently follows an asymptomatic clinical course. According to the diameter, length, and anatomical relation of the aneurysm, and its compressive effects on surrounding structures, surgery or an endovascular treatment can be preferred. In a 65-year-old male patient with ischemic heart disease, who had had a previous coronary angiography in another center, bilateral iliac artery aneurysm and occlusion of the right iliac artery were incidentally diagnosed during a coronary angiography. While coronary artery disease needed a medical treatment, surgical treatment was scheduled for bilateral iliac artery aneurysm. Bilateral iliac arteries were explored through an abdominal incision. After exclusion of the aneurysm by sparing only the right internal iliac artery, bypass grafting to the right femoral and left iliac arteries was performed by using a 16/8 Dacron graft. The patient was discharged after an uneventful postoperative course. In conclusion, isolated iliac artery aneurysms may follow an asymptomatic clinical course and the symptoms can be masked by concomitant coronary artery disease. We presented a successful surgical management of a rare pathology of bilateral iliac artery aneurysm.
