Infected abdominal aortic aneurysms (IAAAs) or mycotic aortic aneurysms (MAAs) is considered to be one of the most rare and critical disease because of its high mortality and morbidity rate. The most typical pathogens, which cause IAAAs are Staphylococcus, Salmonella and Streptococcus species. The clinical presentation of this uncommon condition is fever with unknown cause, abdominal, chest or back pain, shock symptoms, loss of consciousness and pulsatile mass. The main diagnostic criteria are clinical manifestation, laboratory, radiological and intraoperative findings. The management of MAAs can be divided into three categories: antibiotic therapy, surgery and endovascular repair. Open surgery repair is commonly referred as the gold standard in the treatment of MAAs. Based on different literature sources surgical repair can be divided into aneurysm excision and ligation without arterial reconstruction, excision with immediate reconstruction, excision with interval reconstruction or extraanatomic bypass (EAB) and in situ graft placement.
