“…The findings of previous studies have suggested three potential sources of infection: (1) septic arterial emboli usually originating from bacterial endocarditis, (2) hema- togenous seeding of the arterial wall during bacteremia from a distant focus other than the heart, and (3) direct extension from an adjacent infectious process or via the lymphatics from the surrounding infectious process [1,2,6]. The hematogenous spread of infections into the vasa vasorum of the aortic wall is thought to be the most common pathogenesis of infected aneurysms, and the most common organisms causing infected aortic aneurysms are Staphylococcus aureus and Salmonella [2,3,7].…”

Infected abdominal aortic aneurysm: early CT findings

et al. 1998

View full text Add to dashboard Cite

We describe computed tomographic (CT) findings at the early stage of infected abdominal aortic aneurysm in three patients. Periaortic mass and increased fat density were the characteristic findings of early aortic infection on CT. Similar findings caused by other diseases may be difficult to differentiate by imaging alone, but these findings should be used to trigger close follow-up for patients with suspected infected abdominal aortic aneurysm.

“…[1][2][3][4][5] Most patients with mycotic aneurysms have a predisposing factor to infection such as a previous history of endocarditis, alcoholism, or miliary tuberculosis. 2 However, we recently encountered a previously healthy patient who developed a mycotic aneurysm in the infrarenal abdominal aorta, for which a successful in-situ reconstruction of the aorta with prosthetic graft was performed.…”

Infected atherosclerotic ulcer of the abdominal aorta as a cause of mycotic aneurysm treated by in-situ prosthetic graft reconstruction: Report of a case

et al. 1998

A 68-year-old man with an infrarenal mycotic aneurysm underwent successful in-situ graft reconstruction using a woven Dacron graft. A tissue culture taken from the excised aortic wall revealed Staphylococcus epidermidis, and histological study subsequently showed penetrating atherosclerotic ulcers (PAU) involving all layers of the aortic wall and marked neutrophilic infiltration with abscess formation inside the ulcer. Atherosclerotic aortic lesions such as PAU are considered susceptible to bacterial infection, which may lead to the formation of an aneurysm after destruction of the vessel wall. Hence, elderly hypertensive patients, being at high risk for such aortic pathology, require careful studies performed to assess the aorta. The usefulness of computed tomographic (CT) scans to determine the presence of PAU or surrounding inflammation should be borne in mind even when a small mycotic aneurysm exists.

A 30-year retrospective review identified 13 patients treated for infected aneurysms of the abdominal aorta or iliac arteries, for an overall incidence of 0.65%. A constellation of clinical findings led to the correct preoperative diagnosis in 11 (85%) of 13 patients. Treatment methods included resection and in situ replacement grafting in seven patients, resection and extra-anatomic bypass in five patients, and resection-ligation in one patient. Four (31%) of 13 patients died within 30 days of operation, three of whom died of rupture. Overall, good results were achieved in five patients (38%), while poor results were noted in the remaining eight patients (62%). The determinants of outcome were aneurysm location or rupture, the presence of established infection, and the virulence of the infecting organism. In 10 (77%) of the 13 aneurysms, Salmonella species, Bacteroides fragilis, Staphylococcus aureus, and Pseudomonas aeruginosa accounted for all deaths, ruptures, and suprarenal aneurysm infections. These data suggest that patients with primary infections of the abdominal aorta or iliac arteries continue to present with advanced infections or aneurysm rupture that result in a high mortality.
