We report a case with Crawford type III thoracoabdominal aortic aneurysm associated with occlusion/stenosis of the visceral and the iliac arteries necessitating surgical repair. The patient was a 54-year-old man. His visceral arteries were obstructed except the left renal artery which was stenotic. His iliac arterial system was also completely occluded except the patent left common and internal iliac arteries. The blood flow of his visceral organs and lower extremities depended on the collateral vessels from the left internal iliac artery. We successfully performed thoracoabdominal aortic aneurysm repair concomitant with reconstruction of the visceral arteries and the femoral arteries using partial cardiopulmonary bypass between the left internal iliac artery and the left femoral vein. It is important to select appropriate adjuncts and surgical options for patients with thoracoabdominal aortic aneurysms that involve visceral/iliac arteries.
