An infected aneurysm[1] is an aneurysm arising from bacterial infection of the arterial wall. It can be a common complication of the hematogenous spread of bacterial infection.[2]
Intracranial mycotic aneurysms (ICMAs) complicate about 2% to 3% of infective endocarditis (IE) cases, although as many as 15% to 29% of patients with IE have neurologic symptoms.[3] Staphylococcus and Salmonella spp. are the most common organisms that cause mycotic aneurysms of the aorta.[4][5] Anaerobic bacteria such as Bacteroides and Clostridium spp. can also cause aortic mycotic aneurysms.[5] Aortic aneurysm is a rare complication of Mycobacterium tuberculosis infection, most commonly from direct extension of adjacent lesions, but also as a result of hematogenous dissemination.[6]
Treatment
Mycotic abdominal aorta aneurysm (MAAA) is a rare and life-threatening condition. Because of its rarity, there is a lack of adequately powered studies and consensus on its treatment and follow up. A management protocol on the management of mycotic abdominal aortic aneurysm was recently published in the Annals of Vascular Surgery by Premnath et al.[7]
