[Endovascular stent-grafting for mycotic thoracic aortic aneurysm]

We report 3 cases of endovascular stent-grafting (ESG) for mycotic thoracic aortic aneurysm. The case 1 was a rupture of pseudoaneurysm of the descending aorta caused by mediastinitis due to perforation of esophageal ulcer. The patient underwent emergent ESG for temporary control of the rupture. He underwent esophagus reconstruction 5 month after ESG. The case 2 was admitted due to inflammatory reaction. She was diagnosed with mycotic descending aortic aneurysm and underwent elective ESG because of her old age. Her postoperative course was uneventful and no infection recurred. The case 3 underwent ESG for a ruptured mycotic descending aortic aneurysm. But 113 days after ESG, he underwent ESG again for a ruptured endoleak of the stentgraft. His blood culture demonstrated methillin-resistant Staphylococcus aureus (MRSA). He died of rupture to bronchus and esophagus at 18th day after ESG. We believe that ESG is useful in high risk patients for temporary management of the rupture.
