Endovascular approach is now a safe and effective technique for the elective treatment of a thoraco-abdominal aneurysm. This technique has significantly reduced the morbi-mortality for elective surgery. Moreover, it can permit to treat patients with a high surgical risk who are not eligible for open surgery. The permanent availability of endovascular material opens the door for treating a complex emergency thoraco-abdominal aneurysm. Here, we present the case of an 81-year-old man who had a rapidly evolving salmonella-infected aortic thoraco-abdominal Type IV pseudoaneurysm. Total endovascular treatment using aortic endoprosthesis, chimneys for coeliac trunk and superior mesenteric artery and periscopes for renal arteries was performed and permitted to obtain the complete exclusion of the pseudoaneurysm. The patient was event free and discharged from hospital after a few days with an antibiotic treatment adapted for salmonella. He was still event free 10 months after surgery. Endovascular technique might be a viable option even for an emergency infected complex thoraco-abdominal aortic aneurysm. Secondary open surgery should be discussed under the benefit-risk balance.
