Primary infectious aortic aneurysm: a case series and review of the literature

Abstract

Infectious aneurysms, formerly known as mycotic aneurysms, are rare, most often involve the aorta in young patients, and have a greater tendency to rupture than aneurysms of other etiologies. The most characteristic shape is saccular and the most common etiologic agents are Staphylococcus sp. and Salmonella sp. There is scant and imprecise information in the literature about correct nomenclature, diagnosis, and treatment. The authors present three cases in which diagnostic and therapeutic procedures were documented. In addition to reporting this case series, the authors also present a review of the subject, outlining pertinent diagnostic and therapeutic strategies.

Infectious aortic aneurysms: A case report and review of cases from the Middle East and North Africa (MENA) region

“…The most common etiological microorganisms that have been identified are Staphylococcus spp. and Salmonella spp [1] . Other identified microorganisms include Treponema pallidum, Mycobacterium spp., Pseudomonas aeruginosa, Listeria, Klebsiella, E. coli, Clostridium, Campylobacter, H. influenzae, Yersinia, Acinetobacter, Brucella, and fungi [ 1 , 2 ].…”

In tuberculosis (TB), involvement of the aorta among all cardiac structures is the rarest (0.3%) [2] .…”

“…It is estimated that only 1 to 3% of all aneurysms have an infectious origin. This disease carries a high risk of rupture, and hence, mortality [1] . The most common etiological microorganisms that have been identified are Staphylococcus spp.…”
