Isolated iliac aneurysm is rare and difficult for surgery repair because it locates in the deep pelvis. Endovascular repair is preferred currently, and internal iliac artery is generally embolized in order to avoid the endoleak. Embolization of the internal iliac artery can lead to the complications such as buttock claudication, colon ischaemia and erectile dysfunction. Therefore, the antegrade flow of internal iliac artery should be reserved. One seventy-seven-year-old male patient with isolated left common iliac aneurysm, 30 mm in diameter, was successful endovascular repaired using fenestrated covered stent. At 1-month follow up, the patient was asymptomatic. Computed tomography scan shows the iliac aneurysm was completely excluded, and the antegrade flow of the left common, internal and external iliac arteries were normal.
