Infected abdominal aortic aneurysm (IAAA) is a particularly challenging condition in the field of vascular surgery. It is resulted from the infection of the abdominal aorta directly or indirectly caused by pathogenic microorganism, characterized by rapid development, high risk of rupture, high mortality and poor prognosis. The treatment of IAAA currently is performed by means of endovascular aortic repair or surgical procedure on the basis of full course of antibiotic therapy. Here, the authors address the current experiences and advances in diagnosis and treatment of IAAA in China and abroad, so as to provide reference for optimum individualized therapy of the patients.
