A 50-year-old woman who had received hemodialysis for 8 years was admitted due to lumbago, fever and leukocytosis. Computed tomography and angiography revealed a supraceliac saccular aneurysm and right pleural effusion. Impending rupture of an infected supraceliac aneurysm was strongly suspected, and an emergency operation was performed. The aneurysm was almost completely resected and replaced by a 24mm Hemashield graft with reconstruction of visceral and intercostal arteries using partial bypass and deep hypothermia. Staphylococcus aureus infection was diagnosed based on the culture of the aneurysmal wall. The postoperative course was uneventful without any adverse neurological symptoms. After surgery, antibiotics were administered for 4 weeks intravenously. The patient is well 22 months after the operation.
