Introduction: Infectious aneurysms are a rare disease and are characterized by infection of the involved vessel wall. The best treatment is definitely not established. Aim: To describe a case of infectious aneurysm with endovascular management. Case report: We present a 75-year-old male patient admitted to a table compatible with acute abdomen and that an infectious aneurysm of the celiac trunk is investigated in the postoperative period, treated with an endoprosthesis and antibiotic management. Discussion: The traditional management of the infectious aneurysm is open surgery that includes the removal or exclusion of the aneurysm and its infected perivascular tissue, but it leads to great morbidity and mortality. Conclusion: The infectious aneurysm can be managed minimally invasively with endovascular technique, with immediate low morbidity, but with long-term results that are still inconclusive.
