Abstract
A 78-year-old man presented at a clinic 2 years previously with angina. Coronary computed tomography (CT) angiography revealed a saccular aneurysm of the descending aorta. The patient was referred to our hospital where he underwent thoracic endovascular aneurysm repair. Two years later, he was admitted to a nearby hospital with a fever and a body temperature of 38°C. Tests showed elevated white blood cell count and C-reactive protein level, and the patient was administered antibiotics and referred to our hospital. CT revealed thickening of the stent-graft outer aortic wall and expansion of the contrast effect compared with that on the previous scan. Therefore, we suspected infection of the aortic wall and the patient underwent surgery to remove the stent-graft, excise the aortic wall, and replace the descending aorta to the graft. On postoperative day 11, the patient was discharged. He experienced no recurrence of infection for 6 months postoperatively. Careful postoperative follow up is necessary following placement of a stent-graft for saccular aneurysm.
